UDC1000 & UDC 1500MICRO-PRO SERIES

UNIVERSAL DIGITAL CONTROLLERSEN0I-6041 11/98 PRODUCT SPECIFICATION SHEET

OVERVIEWThe UDC1000 & UDC 1500 aremicroprocessor-based 1/16 DIN and1/8 DIN controllers which combine ahigh degree of functionality andreliability at low cost.They are fully dedicated to monitor andcontrol temperatures, pressures andlevels in a wide range of applicationssuch as the plastics and foodindustries, furnaces, packaging andenvironmental chambers. The largeand easy-to-read dual 4-digit displayand tactile keypad make the UDC1000 and UDC 1500 easy to configureand use. Their outstanding flexibilityenables you to configure any unit forany application and change it ifrequired.

FEATURESDual DisplayTwo 4-digit displays with 7 LEDsegments, each configurable for :� PV & SP (non adjutable)� PV & SP (adjutable)� PV & Ramping SP� PV only

Easy to configureTwo different configuration levels(configuration mode and set-up mode)provide easy access to parameters. A4-digit security code preventsunauthorized changes.

Moisture resistant front-faceMeets NEMA 3 / IP65 front-faceprotection against dust and water.

Universal inputAccepts seven different types ofthermocouples, RTD’s, current andvolt linear inputs. All inputs areconfigurable as standard.

Universal power supplyThe UDC 1000 & UDC 1500 canoperate on any line voltage from 90Vac to 264 Vac at 50/60 Hzcontinuously. A 24/48 Vac/dc model isavailable as an option.

Easy output selection andupgradeWith only two basic modules (currentand relay output) and plug-in options,you can configure the controller as youwant for a wide range of applications.

Up to three outputsThe UDC 1000 & UDC 1500 provideup to three outputs for time and currentproportioning, duplex mode(heat/cool), PV or SP retransmission,and alarms.

Alarm strategyTwo soft alarms on PV, deviationhigh/low/absolute. A special loop alarmis also provided to detect faults in thecontrol loop by continuously analyzingthe PV response to the control output.Alarm inhibit is available on power upand setpoint switching.

Manual/Automatic modeManual control (via bumpless transfer)is enabled by simply pressing thefront-face AUTO/MAN key. The “SET”LED flashes and the output power isdisplayed on the lower display. Outputcan be adjusted with the upper andlower keys.

Pre-tuning and self-tuningstrategyPre-tuning is used to set up the PIDparamaters close to the optimumvalues which might be used by theself-tuning algorithm to subsequentlyoptimize the tuning parameters.

Limit ControllerPackaged in 1/16DIN, the UDC 1000limit controller is designed to provide asafety cut-out and optional alarms foruse in a wide variety of applications.

EN0I-6041 11/982

Setpoint rampAccording to a defined ramp rate, theSP ramps the current setpoint to thenew targeted setpoint.

Dual SetpointDual setpoint option is available on theUDC 1000 & UDC 1500. The currentsetpoint is selected by a digital input.This option is exclusive with UDC 1000limit model remote alarm reset.

CommunicationAn optional RS485 communicationsinterface is available on the UDC 1000& UDC 1500. It provides a link betweenup to 32 units and a host computerthrough ASCII or Modbus RTU protocolat up to 9600 baud.

Highly secureA non-volatile memory based onEEPROM technology ensures dataintegrity during loss of power supply,with retention of more than 100 years.The design is centered around a batteryconcept. A 4-digit security codeprevents unauthorized or accidentalchange.

PHYSICAL DESCRIPTIONThe UDC 1000 controller is housed in a110 mm (4.33 inches) deep case withthe standard UDC grey bezel. It can bemounted in a 1/16 DIN panel cutout.The UDC 1500 controller is housed in a100 mm (3.94 inches) deep case andcan be mounted in a 1/8 DIN panelcutout.By using the pre-assembledmounting fixture delivered with the unit,you can easily and securely install thecontroller into the panel cutout. Modularplug-in construction allows rapid accessand saves time. All inputs and outputsare connected on the rear terminalblock by screws.

OPERATOR INTERFACEFour display combinations are offeredto the operator. The upper 4-digit 7-segment display is always dedicated tomonitor the PV. The lower display canshow :� SETPOINT (read only)� SETPOINT (adjustable)� RAMPING setpoint (ramp mode)� BLANK

UNIVERSAL INPUTSAll input types are available on anyunit. By positioning a jumper on theCPU board, the thermocouples, RTD’sor linear input families can be fieldselected. Selection among the varioustypes of inputs is made by promptconfiguration. As soon as the ProcessVariables reaches a value of the inputrange limits, the controller displays amessage. A sensor break indication isalso provided. A configurable digitalfilter is available from 0.5 sec. to 100.0sec.

OUTPUTSThree types of outputs (RELAY, SSRdriver or DC linear) are selectable forthree outputs, through the modelselection guide or by adding a plug-inmodule for outputs 2 and 3.

OUTPUTS ALGORITHMSThe UDC 1000 & UDC 1500 areavailable with the following outputalgorithms :� Time proportional :

ON/OFF or time proportional withelectromechanical relay SPDT 2Aor SSR driver (open collector).

� Current proportional :Supply directly proportionalcurrent or volt signal to the finalcontrol elements which require 0-20 mA, 4-20 mA, 0-10 V or 0-5 V.

� Time proportional duplex :Three duplex modes can beselected, either ON/OFF duplex ortime proportional duplex(heat/coolwith two proportional bands, twocycle times and deadband) orTPSC.

� Current proportional duplex :In addition to the first current/voltoutput, provides a second similaroutput with its own proportionalband.

� Current/Time or Time/Currentduplex :Provides a variation of traditionaltime or current duplex mode bymixing current and timeproportioning together.

CONTROL ALGORITHMSFour control algorithms can be set upthrough the configuration menu :� On/Off � PID� PD + MR � TPSCThe TPSC (Three Position StepControl) control algorithm isdedicated to control valve positioningwithout slidewire feedback from themotor shaft.

CONFIGURATIONThere are two levels of configuration.The SET-UP mode allows modificationof current parameters such as tuningparameters, alarm values, setpointlimit, ramp enable, auto-manual modeenable; auto-pretune enable.The CONFIGURATION mode is moreoriented to unit personality : inputselection, output 2 & 3 usage, alarmtype, communication address, lockoutcode, hardware definition coding.

CONTROL MODEManual or automatic mode withbumpless transfer is standard feature.In manual mode, the operator candirectly control the output through thetwo front face keys (raise and lowerkeys). The output value is monitoredon the lower display.

ALARMSOutputs 2 and 3 can be used asalarms. Two electromechanical singlepole double throw relays can activateexternal equipment when alarmsetpoints are reached. An LED is alsoactivated on the front-face. A direct orreverse acting alarm output can beconfigured. A logical combination ofthe two alarms : OR, AND orhysteresis (active when both alarmsare active, becomes inactive whenboth alarms are inactive) can be setwhich associates the two alarms statusbefore energizing the relay. In order todetect a defective control loop, thecontroller can supply a special loopalarm control by continually monitoringthe PV response to output demand. Atimer is automatically set up when anyoutput is on saturation mode. Whenthe timer reaches twice the reset timewith no PV response, then the loopalarm is activated. With this soft alarm,there is no need for a heater breaker,saving wiring time and costs.

DISPLAYDual, four digit LED display withdecimal point location configurable upto three places for linear ranges only.

LIMIT CONTROLLERThe UDC 1000 1/16 DIN limitcontroller provides a latched relayoutput which is activated whenprocess parameters either exceed orfall bellow the desired value, providinga fail safe cut-off which has to bemanually re-set before the process cancontinue.

The UDC 1000 limit controller can beconfigured to be either a “high limit”unit where the delay will de-energizewhen the PV is above the limitsetpoint, or a “low limit” where therelay will drop out when the PV fallsbelow the setpoint.

LED indication shows when limits havebeen exceeded, and when the relay islatched out.
