2 Introduction to explosion protection through intrinsic safetyWhen introducing electrical equipment in a hazardous area, extensive regulations must be observed that are subdivided into European (EU) and national requirements. The European standards define the general specifications and the detailed guidelines for methods of protection against explosion. The national requirements primarily contain the installation criteria. Electrical instruments for explosion groups I and II, as well as the T1 ... T6 temperature classifications, are grouped in DIN EN 50014 (see "Division of Hazards, Ignition Hazards due to Sparks and Hot Surfaces" in the following table). DIN EN 50020 presents categories, design and test specifications and type identification of intrinsically safe apparatus. Approvals for electrical instruments that are used in explosive environments are regulated by EG-Ex-Framework Guidelines 76/117/EWG and Guideline 94/9/EG.The intrinsic safety method of explosion protection always relates to intrinsically safe circuitry that comprises an intrinsically safe apparatus, an appropriate electrical power source and the connecting cables. In intrinsically safe circuits, an explosive environment cannot be ignited by sparking or a thermal effect when operating normally under prescribed fault conditions. In an intrinsically safe circuit for categroy ia, 2 calculable faults (see definition EN 50020) must not cause an ignition and in category ib only 1 such fault is permissible. Limiting the power supply, total inductance and total capacitance within the intrinsically safe circuitry is the basic principle of the intrinsically safe explosion protection method.The project manager or user has to compare the permissibleinternal limit values for intrinsically safe electrical apparatuswith the permissible connection values of the associatedelectrical apparatus, in accordance with the following table:

These limit values are obtained from the prototype test certificate. The comparison of the limit values satisfies the requirement of DIN EN 60079-14 with regard to the demonstration of intrinsic safety. When installing complex intrinsically safe circuitry with more than one item of associated electrical apparatus, a calculated demonstration of intrinsic safety has to be carried out and this must then be referenced back to the explosion limit curves for DIN EN 50020 or to the tables that these curves represent.In this case all the active associated electrical apparatus are combined in one complex associated electrical apparatus.

"Active" refers to any apparatus that can provide power to the intrinsically safe circuit under normal or malfunctioning operating conditions.For the intrinsically safe connection terminals of this complex apparatus, the effective values for the maximum output voltage U0,

the maximum output current I0,

the maximum output power P0,are calculated as follows, depending on the combined circuitry of the individual associated apparatus:For parallel circuits: I0 from the sum of the individual currents,

U0 from the maximum value of the individual voltages.

For series connection: I0 from the maximum value of the individual currents,

U0 from the sum of the individual voltages.

The individual values are taken from the certificates of conformity.The maximum output power is calculated from the following formula for assigned apparatus with linear current-voltage output characteristics:

P0 = 1/4 x U0 x I0Based on the calculated maximum value, the intrinsic safety has to be checked using the ignition limit curves. DIN EN 60079-14 references limitations (PTB report ThEx-10 is to be used for associated apparatus with non-linear current-voltage characteristics) and safety factors.In addition to this demonstration of intrinsic safety, the integrity of the intrinsically safe circuitry must also be assured against the ingress of energy from other electrical power sources. If both requirements are fulfilled, a safe power limit within the circuitry will not be exceeded, even if there is an interruption, a short-circuit or grounding of the circuitry (EN 60079-14). A detailed description of "Explosion protection through intrinsic safety" can be found in the manual of the same name.The previously valid national specifications will be replaced in the future by the following European standards:

3 Introduction

3.1 A brief overview of the intrinsically safe IS-RPI Remote Process Interface

In many production installations, e. g. the chemical and petrochemical industries, onshore and offshore installations, pipelines, etc., there are areas with potentially explosive atmospheres. In order to provide protection, safety and proper functioning, the signal circuits for measurement, control, regulation and monitoring must be implemented with the ignition protection class: intrinsic safety. In addition to the actual input and output components of the programmable logic controller (PLC) or the process control system, interface components are needed to ensure that the signal circuits are protected against explosion in case of failure.Pepperl+Fuchs has been the leading supplier of such interface components for many years. These components are available on Eurocard or as modular housings (K-systems). The intrinsically safe Remote Process Interface (IS-RPI) will

eliminate the need for previously required intrinsically safe barriers/isolators and the physical separation of control and process, since the entire IS-RPI system will be approved in the intrinsically safe ignition protection method. This allows the interface to be installed directly nearby the controlled equipment in the hazardous area. The IS-RPI system is designed for use in Zone 1 of the hazardous area, i. e. it can be used directly in the potentially explosive atmosphere. This distinguishes the IS-RPI completely from conventional interface components which must be installed in safe areas.

The primary goals in developing the IS-RPI are a high level of technical performance, avoiding additional, costly installations and making the system attractive to wide range of users. To this end, the system is also developed for operation at ambient temperatures up to 70 °C.

Essential system features:• instrumentation directly in the field• intrinsically safe modules• open system by gateway• power Supply in EEx de• Tu: -20 °C ... +70 °C

3.2 Range of application

In many production industries, there are plants having areas with potentially explosive atmospheres:

• chemical and petrochemical industry• pharmaceutical and cosmetics industries• paint plants• food industry• sewage treatment Explosion protection for electrical measurement, control and feedback of processes is frequently listed in the "Intrinsic safety" protection class. An intrinsically safe circuit, when operated in accordance to regulations and under certain fault conditions, can cause neither a spark nor a thermal effect which could cause the ignition of an explosive atmosphere. The basic principle of the "Intrinsic safety" ignition protection class is limiting the output, voltage and current in the intrinsically safe circuit.

In order to also ensure protection against explosion in case of failure with intrinsically safe circuits, special interface components are now used which separate the intrinsically safe circuit from both the non-intrinsically safe circuit and circuits installed in the non-Ex areas, e. g. K-system devices and the Remote Process Interface from Pepperl+Fuchs.

Cabling costs are an important factor with installations that are spread out over a wide area since the intrinsically safe field circuit wiring must be run out of the Ex area to the interface components. From there, the I/O signals must then be run in the non-Ex area to the control system. The Remote Process Interface from Pepperl+Fuchs drastically reduces the required wiring since the I/O signals are transmitted in the non-Ex area to the control system using a field bus system.

EEx i interface solution from Pepperl+Fuchs

The intrinsically safe remote process interface IS-RPI from Pepperl+Fuchs, which can be installed directly in the hazardous area, and which transfers I/O signals via an intrinsically safe fieldbus into the safe area is very well suited

for measuring, control, feedback and monitoring in this area.Only a simple field bus barrier (segment coupler) with galvanic separation must be used to isolate the Ex and the non-Ex areas.

3.3 System layout and principle of operation

The system fullfills requirements in accordance with EEx ib IIC T4, I/O signals of the modules are designed according to EEx ia IIC, while the modules themselves are mounted in the hazardous area.

The signals are digitised via the modules and transmitted via a serial data bus to the gateway. This gateway, at the same time, establishes the interface to a standard bus. One gateway can address a maximum of 8 modules with up to 16 channels per unit.

The intrinsically safe fieldbus going out from the gateway is first directed in the safe area (non-Ex) to a segment coupler for safe signal separation. From there, the bus is connected directly to the PLC or to the distributed control system (DCS).

In this manner, there is no need for any wiring on the non-Ex side apart from the bus line as it is known from conventional systems. A further potential for savings is that the I/O interfaces of the PLC or DCS are eliminated.

3.4 Operating principle

Intrinsically safe signal circuits are connected on the module carrier of the interface module using self-opening screw terminals or spring-loaded terminals with a maximum conductor cross section of 2.5 mm². This type of connection allows a simplified cabinet design and, should service become necessary, permits the unit to be replaced under power.

Binary input signal processing is carried out in 16 channel isolated switch amplifiers. Binary output signals are transmitted

by 4-channel solenoid valve driver modules. 8-channel current repeaters, analogue driver/repeaters and universal RTDs are available for processing analogue measurement value signals.

The intrinsically safe signal circuits are galvanically isolated from the power supply and the backplane bus. The backplane bus is a manufacturer-specific system and guarantees time equidistant signal transmission. The update time is dependent on the type and number of bus elements.

Cycle timeExample: A system with 8 analogue input modules (i. e. 64 channels) has a cycle time of approximately 1.6 ms. The gateway serves as an interface to the primary bus system. It is also possible to connect to different bus systems, for example PROFIBUS, MODBUS etc.

A system malfunction is identified and reported to the host system. If a unit fails, an identical, new unit is connected in place of the defective unit. The gateway automatically assigns the parameter set block of the original unit to the replacement unit.

3.6 Structure of the IS-RPI HART system

System descriptionIn process-related systems, there are many field devices distributed over a large area. Key rating data of these field devices must be monitored or logged in the context of ISO 9000, for example or must be adjusted if process variables are changed.

The IS-RPI HART system of Pepperl+Fuchs allows for online communication between a PC and "smart" field devices that support the HART protocol.

SMART field devices (transmitters, intelligent actuator controllers and similar devices) make it possible to store information such as the measurement range, tag number, ID number, manufacturer, etc. in the field device itself. Access to these data is usually obtained using a handheld terminal. This means that when changes to information are required, connection to the field device must be carried out manually.

If specific data must be logged as part of a quality assurance program based on ISO 9000, this means increased overhead for the process control system or for the PLC. Thus, the corresponding data must be queried cyclically and stored in a database by the system, for example.

The IS-RPI HART system of Pepperl+Fuchs creates a link between the PC and intelligent "HART-capable" field devices. All access to the field device takes place in parallel to the transfer on the bus and the 4 mA ... 20 mA measurement signal, and therefore has no effect on the processing of measurement values by the process control system.The system thus provides a subordinate service interface. It is also possible to record measurement values with the IS-RPI HART system. Up to 8 HART field devices can be connected to each IS-RPI HART I/O module. 8 of these IS-RPI HART I/O modules together with a gateway form a rack with a complete structure. Up to 100 gateways can form a complete system for bus systems used by IS-RPI. In this manner, up to 6400 field devices can be addressed and data exchanged with one PC (8 x 8 x 100). It is also possible to continue working with a handheld terminal, since the HART protocol accepts two masters, for example a PC and a handheld terminal, in one system. To do this, however, "Secondary Master Enable" must be set in the configuration. This setting is turned off in the configuration in its basic factory setting.

Integration into user software (Asset Management Systems)The IS-RPI HART system exhibits its full functionality through integration into modern HART maintenance systems such as PACTware™.The user control tools integrate the functions of the device in the form of menu commands into a uniform user interface and

convenient control environment. The presentation and description of the functions in the individual operating tools can be very different, however. Thus no generally applicable presentation is possible here.

You will find notes on configuring and operating as well as parameters and diagnostic options for it in the documentation on operating tools.

This power supply is galvanically isolated andlimits the amount of available energy from the user-provided, non-Ex power supply to the field side of the I/O modules.Each power supply has 4 galvanically isolated channels for the supply of IS-RPI I/O modules. The power supply is contained inan encapsulated, explosion protected and flameproof housing.All transmitters, actuators, sensors, etc. are supplied with power via the I/O modules.The total number of required Ex power supplies depends on the installed components and the total system configuration.

Planning of the intrinsically safe power supplyOnce the type and number of needed IS-RPI modules and, if necessary, their distribution over several IS-RPI systems have beendetermined, you can move on to the type and number of intrinsically safe power supplies which will be needed.Pepperl+Fuchs offers several types of power supplies which are specially designed for the IS-RPI, they are:

Power packs of types RS**-PSD*-Ex4.34, installation in potentially explosive environments• 4 intrinsically safe outputs 8.5 W each• Permissible ambient temperature -20 °C ... +70 °C• Installation in the hazardous area• 2 input voltage variants:

RSD2-PSD2-Ex4.34) 18 V V DC ... 31.2 V DCRSA6-PSD-Ex4.34) 85 V AC ... 264 V AC

First select the type of power pack To determine the number of intrinsically safe power packs required, you must calculate the output requirement of all IS-RPIdevices (gateways, I/O modules, copper/light wave guide adapters, etc.) in the hazardous area.The following diagram illustrates how many IS-RPI devices can be supplied from an 8.5 W power pack channel and how high thepower consumption of the devices is.

Number of devices supplied with a power pack channel

Now calculate the required number of power supply channels and determine which devices and modules should be supplied fromwhich power pack channel.

Example:

A system consisting of 3 IS-RPI branches and the following components shall be supplied with intrinsically safe power:• 3 PROFIBUS gateways• 4 modules RSD-BO-Ex4 with 4 binary outputs each• 9 modules RSD-BI-Ex16 with 16 binary inputs each• 7 modules RSD-TI-Ex8 with 8 temperature/mV inputs each

4-channel power packs of type RSD2-PSD2-Ex4.34 should be used.

In determining the number of power packs required, it is essential to consider the maximum permissible lead lengths for intrinsically safe output channels.

Make certain to provide power supplies for any fieldbus components that may be present such as copper/light wave guide adapters.

Example of calculating the number of power pack channels required

Each gateway and each binary output module requires its own power pack channel:3 x 8.5 W (GW) + 4 x 8.5 W (BO) = 7 x 8.5 W, thus 7 power pack channels

Each binary input module requires 2.8 W, i.e. one power pack channel can provide power to 3 modules:9 x 2.8 W (BI) = 3 x 8.4 W, thus 3 power pack channels

Each temperature/mV input module requires 1.5 W, i.e. one power pack channel can supply power to 5 modules:7 x 1.5 W (TI) = 10.5 W, thus 2 power pack channels

A total of 12 power pack channels, thus 3 power packs of type RSD2-PSD2-Ex4.34 are required.

4.4 Switch cabinet layout

For installing the IS-RPI system, Pepperl+Fuchs offers complete solutions for the switch cabinet. The most suitable solution for your system depends strongly on the size of the installation (number of IS-RPI modules and systems) and the number of power supplies.

Heat in the switch cabinet continues to play an important role.|Contact your local Pepperl+Fuchs sales office for information concerning the optimal cabinet solution for you. Pre-mounted cabinet solutions, which save on planning work, are also available on request.

Planning the mechanical layoutSelection of the switch cabinet

Because of considerations arising from "power supply concepts", the extent and physical arrangement of an IS-RPI system cannot be changed. You can now start with a selection of suitable switch cabinets.

The following questions must be answered in order to select the proper cabinet:

• How many IS-RPI systems will be installed in one cabinet?• Will the power supplies also be installed in the cabinet?• Will all the devices be installed in one large cabinet or in

several smaller cabinets?• How much heating is there in the cabinet?• Will an inside temperature (= max. operating temperature of

the IS-RPI) of 70 °C be exceeded?

4.5 System arrangement in the switch cabinet

The arrangement of the IS-RPI components and power supplies in a cabinet saves space compared to conventional systems.

Both horizontal and vertical layouts are possible in the cabinet.

The following two diagrams illustrate possible arrangements within the cabinet.

To save space, two IS-RPI systems can be kept in the switch cabinet

Since the ambient temperature has a direct effect on the service life of modules, we recommend mounting power packs outside the switch cabinet. This will keep internal heat to as low a level as possible.

Space-saving layout of three IS-RPI systems in a cabinet

Please note for the planning and installation of an IS-RPI system that the gateway must always be positioned to the left of the modules.

Separate labelling strips or similar items are not required for labelling the field circuits and measurement points. The IS-RPI I/O modules have removable description labels under the front cover that allow each I/O channel to be labelled.

Non-central arrangement of IS-RPIIS-RPI allows an arbitrary mix of I/O modules. Thus IS-RPI can be used as an intelligent terminal box. With this arrangement the mix of I/O modules can be tailor made for the application.

An optimum ratio of I/O signals and required space shows the following example:

IS-RPI as an intelligent terminal boxDepending on the module types, you should be able to wire up to 300 I/O signals per m² of base surface in the example above.

4.6 Structure and arrangement of the system components

Housing typesEach IS-RPI segment includes a gateway and up to 8 I/O modules with a module carrier. The gateway and module carrier are mounted on 35 mm DIN rails (DIN EN 50022) and connected with each other through the backplane bus plug connectors that are integrated into the housing.

The I/O modules can simply be plugged into the module carriers. A mechanical coding switch makes it impossible to plug in the wrong module.

4.7 Mounting IS-RPI gateways and modules

First, all gateways and the module carriers are mounted. The module carriers are used to support and hold the I/O modules.

First snap the gateway onto the mounting rail. Then, starting at the gateway, mount one terminal base after the other. Mounting of the terminal bases is shown in the following figures.

Mounting the terminal bases

Be sure that the sliding connector used to make the backplane bus connection is retracted and locked into place.

Sliding connector for making the backplane bus connection

Once the terminal base is mounted, push the sliding bus connector into the neighbouring terminal base to the left in order to establish the backplane bus connection. Install all remaining terminal bases using this procedure.

Panel mounting

It is also possible to mount the terminal bases directly to a panel. The following figure shows the positions of the two mounting holes.

Mechanical coding of the modules

As the next step, for all terminal bases which are to be plugged into I/O modules, you must turn the rotating coding key into the corresponding position for the particular module type. The coding key prevents the wrong type of module to be plugged into an existing, pre-wired terminal base. Each I/O module type has its own, unalterable coding (position 1 to 7) which is given on the front of the device.

Position of the coding key shown on the front of the device

Position of the coding key for I/O modules

Do not mount the module carriers with the I/O modules plugged in. Doing so may damage the module carriers!

Note

Note the special grounding information if you are not fastening the module carrier on a grounded metal top hat section rail.
