Configuration : ( (1AI + 2AO + 4DO + 1SO)

Size (mm) : 96 x 96 x 120

Technical Specification

ItemMicrocontroller based 5 digit PID Temperature / Process controller
Input -U (Universal)Single Analog Input - RTD(Pt-100)/ 2 or 3 wire and Thermocouple (type J,K,R,S,B,T), 0-10V and 4-20 mA
(i.e. Maximum 8 user selectable inputs using keyboard and DIP switch on the back panel)
RangeFull +ve range of the selected input
(please refer to the input and range selection table)
Decimal PointProgrammable for voltage and current inputs.(1.0 0.1,0.01)
Resolution1 °C /0.1 °C for thermocouples and 0.1oC for Pt-100.
For V and mA inputs the display resolution is subject to the required range.
For V and mA input the position of the decimal point can be selected.
Sampling rate / Display rateThe input is read @40mS / the display is updated @1 second. The control loop is also executed @ 40 mS.
Indicating Accuracy+/- 1 °C or +/-0.1 °C for Thermocouple throughout the range and
+/- 0.1 °C for Pt-100
for (4-20)mA or (0-10)V - absolute to the linear input signal
Burn Out DetectionIn the event of Input being open or short -
the analog output can be programmed to go up scale or down scale and
Digital Output like relay can be programmed to remain ON or OFF.
One Ramp / SoakTo Gradually increase the process value -
Ramp rate : rAmp = 0.0 to 100.0 °C/min or 0 to 100 °C/min
To Hold the controlled process value for required time,
Soak time: St = 0 to 999 minutes.
Display5 digit 0.5" Red 7-segment display for process variable.
5 digit 0.5" Green 7-segment display for set value and PID parameters
Output IndicationsFront Panel LED indications for Control Output, Alarms, Control and A/M status and serial interface etc.
Control AlgorithmPID or ON/OFF selectable (when specified for switching output).
Direct action (cool) or Reverse action (heat) - User programmable.
Reverse Action is considered as Heat output -
where control output decreases as the error (SV-PV) is less positive and vice versa.
Direct Action is considered as Cool output -
where control output increases as the error (PV-SV) is more positive and vice versa.
TuningAuto/Manual tuning of PID values.
PID ValuesProportional Band (P) = 0.0 to 100.0% of Span,
Integral (I)= 0.00 to 5.00 resets/minute,
Derivative (D) = 0.00 to 5.00miutes,
Hysterisis = 0 to 50 counts, Cycle Time = 2 to 100 seconds.
SettingsUsing front panel feather touch (metal dome) key board to set various parameters.
Memory BackupRetention of PID and Set values in the built in non-volatile memory -
in case of power failure and automatic re-execution of control on power resumption.
Control Outputs (Switching)Switching Outputs - DC pulse (0 to 10VDC@25mA) for external SSRs and
Relay or Triac (AC SSR) (rated for 5A @230VAC) for external contactor.
(PID or ON/OFF action - user selectable) or
Control Outputs (Analog)Analog Outputs (4-20)mA (RL max = 300 Ohms) or
0-5VDC (RL min = 10KOhms)
Alarm Outputs2 to 4 extra Relay Outputs with programmable hysteresis for High or Low Alarms.
(relay contacts rated for 5A @230VAC) -
Configurable for High, Low, Deviation and OFF state or as per desired event.
(C and NO contacts are available to the user for each relay)
Serial CommunicationOptically isolated 2 wire RS485 on Modbus RTU protocol.
(in Slave mode with programmable modbus address).
Supply230VAC +/- 20%, 50/60 Hz.
Size96 x 96 x 120 mm.
Panel Cutout92 x 92 mm +/- 0.5 mm.
EnclosureABS plastic with polycarbonate front graphic.
