TC 303 : TEMPERATURE CONTROLLER

Temperature controller

    FEATURES

 - Based on state of art latest microcontroller technology with Watchdog
   feature for fail safe operation.
 - Inputs RTD(PT100), J, K, R, S, T, E, B, N Thermocouples 4-20mA, 0-10VDC
   factory settable.
 - Automatic cold junction compensation for thermocouples.
 - Automatic wirelength compensation for long wire RTD inputs.
 - Very high accuracy 0.25%, with software linearization.
 - Easy on-line field calibration to user by front keys.
 - Reading offset facility to compensate the field error.
 - Two independents set point with individual relay output with hysterisis settable
 - Programmable latch OR non-latch facility for relay output.
 - Isolated RS485 communication with MODBUS RTU Protocol
 - Isolated retransmission output for process value with programmable range
   can be set by user.
 - Flameproof version is available on request.
