Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable
14 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable
14 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
About the Power SuppliesCompact IOtrade power supplies provide 120240V AC and 24V DC power to modules which you can place to the left or the right side of the 1769 power supply As many as eight IO modules can be placed on each side of the power supply
Before You BeginThere are some points about power distribution that you must know
bull The master control relay must be able to inhibit all machine motion by removing power to the machine IO devices when the relay is de-energized We recommend that the controller remains powered even when the master control relay is de-energized
bull If you are using a DC power supply interrupt the load side rather than the AC line power This operation avoids the additional delay of power supply turn-off The DC power supply must be powered directly from the fused secondary of the transformer Power to the DC input and output circuits must be connected through a set of master control relay contacts
Perform Periodic Tests of Master Control Relay CircuitAny part can fail including the switches in a master control relay circuit The failure of one of these switches would most likely cause an open circuit which would be a safe power-off failure However if one of these switches shorts out it no longer provides any safety protection These switches must be tested periodically to make sure they stop machine motion when needed
ATTENTION This equipment is not resistant to sunlight or other sources of UV radiation

(1) Pollution Degree 2 is an environment where normally only non-conductive pollution occurs except that occasionally a temporary conductivity that is caused by condensation can be expected
(2) Over Voltage Category II is the load level section of the electrical distribution system At this level transient voltages are controlled and do not exceed the impulse voltage capability of the insulation of the product
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations
Compact IO Expansion Power Supplies
Assemble the System1769 Compact IO power supplies distribute power from either side of the power supply
The maximum amount of current the system supports in both directions is
bull 1769-PA2 1769-PB2 2 amps at 5V DC 1 amp at 24V DCbull 1769-PA4 1769-PB4 4 amps at 5V DC 2 amps at 24V DC
The power supply can be attached to an adjacent IO module before or after mounting
EXAMPLE A 2 amp at 5V DC power supply (1769-PA2 1769-PB2) can provide 1 amp to the right side of the power supply and 1 amp to the left A 4 amp at 5V DC power supply (1769-PA4 and 1769-PB4) can provide 2 amps to the right side of the power supply and 2 amps to the left
IMPORTANT The maximum amount of current that can be distributed from either side of any 1769 power supply is 2 amps at 5V DC and 1 amp at 24V DC
This condition is a limit of the 1769 Compact IO Bus

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

(1) Pollution Degree 2 is an environment where normally only non-conductive pollution occurs except that occasionally a temporary conductivity that is caused by condensation can be expected
(2) Over Voltage Category II is the load level section of the electrical distribution system At this level transient voltages are controlled and do not exceed the impulse voltage capability of the insulation of the product
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations
Compact IO Expansion Power Supplies
Assemble the System1769 Compact IO power supplies distribute power from either side of the power supply
The maximum amount of current the system supports in both directions is
bull 1769-PA2 1769-PB2 2 amps at 5V DC 1 amp at 24V DCbull 1769-PA4 1769-PB4 4 amps at 5V DC 2 amps at 24V DC
The power supply can be attached to an adjacent IO module before or after mounting
EXAMPLE A 2 amp at 5V DC power supply (1769-PA2 1769-PB2) can provide 1 amp to the right side of the power supply and 1 amp to the left A 4 amp at 5V DC power supply (1769-PA4 and 1769-PB4) can provide 2 amps to the right side of the power supply and 2 amps to the left
IMPORTANT The maximum amount of current that can be distributed from either side of any 1769 power supply is 2 amps at 5V DC and 1 amp at 24V DC
This condition is a limit of the 1769 Compact IO Bus

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable

See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations
Compact IO Expansion Power Supplies
Assemble the System1769 Compact IO power supplies distribute power from either side of the power supply
The maximum amount of current the system supports in both directions is
bull 1769-PA2 1769-PB2 2 amps at 5V DC 1 amp at 24V DCbull 1769-PA4 1769-PB4 4 amps at 5V DC 2 amps at 24V DC
The power supply can be attached to an adjacent IO module before or after mounting
EXAMPLE A 2 amp at 5V DC power supply (1769-PA2 1769-PB2) can provide 1 amp to the right side of the power supply and 1 amp to the left A 4 amp at 5V DC power supply (1769-PA4 and 1769-PB4) can provide 2 amps to the right side of the power supply and 2 amps to the left
IMPORTANT The maximum amount of current that can be distributed from either side of any 1769 power supply is 2 amps at 5V DC and 1 amp at 24V DC
This condition is a limit of the 1769 Compact IO Bus

Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
Assemble the System1769 Compact IO power supplies distribute power from either side of the power supply
The maximum amount of current the system supports in both directions is
bull 1769-PA2 1769-PB2 2 amps at 5V DC 1 amp at 24V DCbull 1769-PA4 1769-PB4 4 amps at 5V DC 2 amps at 24V DC
The power supply can be attached to an adjacent IO module before or after mounting
EXAMPLE A 2 amp at 5V DC power supply (1769-PA2 1769-PB2) can provide 1 amp to the right side of the power supply and 1 amp to the left A 4 amp at 5V DC power supply (1769-PA4 and 1769-PB4) can provide 2 amps to the right side of the power supply and 2 amps to the left
IMPORTANT The maximum amount of current that can be distributed from either side of any 1769 power supply is 2 amps at 5V DC and 1 amp at 24V DC
This condition is a limit of the 1769 Compact IO Bus

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable
14 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
Follow these steps to assemble the Compact IO system
1 Disconnect your line power
The power supply does not support removal or insertion of modules under power
2 Check that the bus lever of the power supply to be installed is in the unlocked (fully right) position
3 Use the upper and lower tongue-and-groove slots to secure the power supply to an IO module
4 Move the power supply back along the tongue-and-groove slots until the bus connectors align with each other
5 Push the bus lever back slightly to clear the positioning tab
Use your fingers or a small screwdriver
6 To allow communication between the controller and the IO move the bus lever of the power supply and its adjacent IO modules fully to the left until it clicks
Make sure it is locked firmly in place
7 Attach an end cap terminator to the last IO module in the system by using the tongue-and-groove slots as before
8 Lock the end cap bus terminator
WARNING If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
ATTENTION When attaching expansion IO power supplies it is very important that the bus connectors are securely locked together to ensure proper electrical connection
IMPORTANT A 1769-ECR or 1769-ECL right or left end cap (respectively) must be used to terminate the end of the serial communication bus

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller

3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
Mount an IO Expansion Power Supply
Minimum SpacingMaintain spacing from enclosure walls wireways adjacent equipment and so forth Allow 50 mm (2 in) of space on all sides for adequate ventilation
Prevent Excessive HeatFor most applications normal convective cooling keeps the system within the specified operating range Verify that the specified temperature range is maintained Proper spacing of components within an enclosure is sufficient for heat dissipation
In some applications other equipment inside or outside the enclosure can produce a substantial amount of heat In this case place blower fans inside the enclosure to help with air circulation and to reduce hot spots near the system
Additional cooling provisions can be necessary when high ambient temperatures are encountered
ATTENTION During panel or DIN rail mounting of all devices be sure that all debris (for example metal chips wire strands) is kept from falling into the module Debris that falls into the module could cause damage on power up

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable

See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

1 Before mounting a power supply or module on a DIN rail close the DIN rail latches
Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable
14 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
2 Press the DIN rail mounting area of the module against the DIN rail
The latches momentarily open and lock into place The following illustration shows a power supply being attached to the IO modules in a DIN rail mounted Compact IO system
Verify Your System PowerYour system power budget is a consideration when using 1769 power supplies This budget determines the power that is being provided to the IO modules See Power Supply Distance Ratings in the CompactLogixtrade System Selection Guide publication 1769-SG001 for the power requirements
1 After you have reviewed the amount of current consumed by your system verify that your power supply has adequate capacity for its bank of IO modules
TIP The total number of IO modules cannot exceed 16 on one bank with a maximum of 8 IO modules on either side of the power supply
You system can be used in a maximum of two banks of IO modules This condition occurs when you configure your system with a MicroLogixtrade 1500 controller one expansion cable one expansion power supply and a total of eight IO modules The expansion power supply cannot be directly connected to the MicroLogix 1500 controller
1769 Cable
14 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
See Temperature Derating on page 25 for graphs
2 To do so compare the current graphs to your totals for the followingbull Total 5V DCbull Total 24V DC
Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Compact IO Expansion Power Supplies
bull Total 24V DC sensor power (1769-PA2 only)
3 If your power supply load is at or above the limits of the allowable ranges that are shown in the graphs you must add an additional IO bank
See Connect the Power Supplies on page 19 for additional information
Power ConsiderationsThe following sections explain power considerations for the Compact IO system
Disconnect the Main Power
Install the main power disconnect switch where operators and maintenance personnel have quick and easy access to it Besides disconnecting electrical power de-energize all other sources of power (pneumatic and hydraulic) before you begin working on a machine or process that is controlled by a controller
Isolation Transformer UsageYou can use an isolation transformer in the AC line This type of transformer provides isolation from your power distribution system to reduce electrical noise and is often used as a step down transformer to reduce line voltage Any transformer that is used with the Compact IO system must have a sufficient power rating for its load The power rating is expressed in volt-amperes (VA) See Schematic (Using IEC Symbols) on page 18 for an example of circuits using isolation transformers
IMPORTANT An additional IO bank must include its own power supply
An end capterminator (1769-ECR or 1769-ECL) must also be used if the IO bank is the last in the system
WARNING EXPLOSION HAZARD
Do not replace components or disconnect equipment unless power has been switched off
If you connect or disconnect wiring while the field-side power is on an electrical arc can occur This could cause an explosion in hazardous location installations Be sure that power is removed or the area is nonhazardous before proceeding
Rockwell Automation Publication 1769-IN028C-EN-P - August 2016 15
Power Supply InrushDuring powerup the power supply allows a brief inrush current to charge internal capacitors Many power lines and control transformers can supply inrush current for a brief time If the power source cannot supply this inrush current the source voltage can sag momentarily
Compact IO Expansion Power Supplies
The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown
16 Rockwell Automation Publication 1769-IN028C-EN-P - August 2016
ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

The only effect of limited inrush current and voltage sag on the system is that the power supply capacitors charge more slowly However the effect of a voltage sag on other equipment must be considered For example a deep voltage sag can reset a computer that is connected to the same power source The following considerations determine whether the power source must be required to supply high inrush current
bull Power-up sequence of devices in a systembull Amount of the power source voltage sag if the inrush current cannot be suppliedbull Effect of voltage sag on other equipment in the system
If the entire system is powered up simultaneously a brief sag in the power source voltage typically does not affect any equipment
Loss of Power SourceThe power supply is designed to withstand brief power losses without affecting the operation of the system The time the system is operational during power loss is called ldquoprogram scan hold-up time after loss of powerrdquo The duration of the power supply hold-up time depends on the type and state of the IO but is typically between 5 millisecondshellip10 seconds When the duration of power loss reaches this limit the power supply signals the processor that it can no longer provide adequate DC power to the system This condition is referred to as a power supply shutdown The processor then performs an orderly shutdown of the controller
Input States on Power DownThe power supply hold-up time is longer than the turn-on and turn-off times of the inputs Because of this the processor can record the input state change from lsquoOnrsquo to lsquoOff rsquo that occurs when power is removed before the power supply shuts down the system Comprehension of this concept is important Write the program to compensate for this effect
Other Types of Line ConditionsOccasionally the power source to the system can be temporarily interrupted It is also possible that the voltage level can drop substantially below the normal line voltage range for a time Both of these conditions are considered to be a loss of power for the system
User Power Overcurrent ConditionThe power supply shuts down if there is an overcurrent condition All outputs latch off and remain off until you remove the overcurrent and cycle power Reload the user program following a power supply shutdown

ATTENTION To avoid unexpected operation due to 24V DC user power shutdown (1769-PA2 only) monitor the 24V DC user output with a 24V DC input channel
Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Compact IO Expansion Power Supplies
Use a Master Control RelayA hard-wired master control relay (MCR) provides a reliable means for emergency machine shutdown Since the master control relay allows the placement of several emergency stop switches in different locations its installation is important from a safety standpoint Overtravel limit switches or mushroom-head push buttons are wired in series so that when any of them opens the master control relay is de-energized This configuration removes power to input and output device circuits
Place the main power disconnect switch where operators and maintenance personnel have quick and easy access to it If you mount a disconnect switch inside the enclosure place the switch operating handle on the outside of the enclosure so that you can disconnect power without opening the enclosure
Whenever any of the emergency stop switches are opened remove power to input and output devices
When you use the master control relay to remove power from the external IO circuits power continues to be provided to the power supply of the system This condition is so that you can still observe the diagnostic indicators on the processor
The master control relay is not a substitute for a disconnect to the system It is intended for any situation where the operator must quickly de-energize only IO devices When you inspect or install terminal connections replacing output fuses or working on equipment within the enclosure use the disconnect to shut off power to the rest of the system
ATTENTION Never alter these circuits to defeat their function since serious injury andor machine damage could result
TIP If you are using an external DC power supply interrupt the DC output side rather than the AC line side of the supply This process avoids the additional delay of power supply turn off
Fuse the AC line of the DC output power supply
Connect a set of master control relays in series with the DC power supplying the input and output circuits
TIP Do not control the master control relay with the Compact IO system Provide the operator with the safety of a direct connection between an emergency stop switch and the master control relay

Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Compact IO Expansion Power Supplies
Wire the Fingersafe Terminal BlockWhen wiring the terminal block keep the fingersafe cover in place
1 Loosen the terminal screws to be wired
2 Route the wire under the terminal pressure plate
You can use the bare wire or a spade lug The terminals accept a 635 mm (025 in) spade lug
3 Tighten the terminal screw making sure that the pressure plate secures the wire
Recommended torque when you tighetn terminal screws is 127 Nbullm (1124 lbbullin)
Wire Size and Terminal Screw TorqueEach terminal accepts as many as two wires with the following restrictions
TIP The terminal screws are non-captive Therefore it is possible to use a ring lug [maximum 14-inch od with a 0139-inch minimum id (M35)] with the module
TIP If you must remove the fingersafe cover insert a screwdriver into one of the square wiring holes and gently pry the cover off If you wire the terminal block with the fingersafe cover removed you cannot put it back on the terminal block because the wires are in the way

Replace the Fuse
Follow these steps to replace a blown fuse
1 Remove Compact IO system power to correct conditions that are causing the short circuit
2 To remove the fuse housing cover place a slotted screwdriver under the tab
3 Use a fuse puller or similar device to remove the fuse
Use care so that the printed circuit board and surrounding electronics are not damaged
4 Replace the front access fuse by centering the replacement fuse over the fuse clip and pressing down
See Specifications on page 31 for information on the front access fuse
If you use a tool to press the fuse in place apply pressure to only the metal end caps not to the center of the fuse
5 Replace the fuse housing cover
