This is a versatile micro-controller based PID Controller with a very high performance. This instrument is made in 96x96x200 mm size with standard cut out of 92x92 mm.Front is sealed membrane type to with stand dusty environment. On back plate, PCB soldered 35 deg. Angled terminals of very good quality are used.

Ø 4 digit 0.56” Red LEDs for process variable.
Ø 4 digit 0.39” Red LEDs for set point.
Ø 20 segment bargraph for control output / valve position indication. Individual discrete Red LEDs to indicate relay status, auto/manual mode, Local /Remote set point, Transmit/Receive status in case of serial communication.
Ø Thermocouple types B, E, J, K, R,S, & T (ANSI standard)
Ø RTD-Pt100 (DIN 43760) 3 - wire
Ø 4-20 mA or 1-5 V DC linear
Ø 4-20 mA or 0-5 V DC linear
Ø Other types on request

request.
2
Auxiliary Relays
: Front panel configurable as absolute / Deviation / Band for
Control / Alarm action,
relay on above / On below set point.
Acknowledge facility
for alarm.
Power
Supply
:
24 V / 30 mA Transmitter Power Supply
Calibration
:
Zero
and span of process variable, remote set point and valve position are
adjusted by digital calibration
through front panel keys.
No trim pot.
Control
:
Set, Digit shift, Increase, Decrease and Enter keys for configuration, operation, programming and
calibration. With the Digit shift key individual digit can be changed directly, so data can be changed
fast instead of normal increment /decrement keys. Data access level programmable for operator
level / supervisor level by DIP switch at back.
Data lock provision by DIP at back to avoid unauthorized data changes.
General :
Ambient : 0 to 55 deg. C
Humidity : upto 95% RH (Non – condensing)
Bezel Size : 96 x 96 mm
Depth behind panel : 220 mm maximum including terminals.
Options : RS 232 C / RS 422 / RS 485 Serial Communication Interface.
