Dual Set Point Temperature Controller

DC-80, Dual Set Point Temperature Controller


Options:-

* 0.10C resolution for RTD input
* Optically isolated output to drive solid-state
   relay.
* 1 inch high 7-segement LED display

SHIVA Controls & Systems' Model DC-80, temperature controller is designed to perform consistently under servere and harsh industrial environments at an economical price. These instruments have standard features including two independent 5Amp SPDT mechanical relays for two outputs with either time proportioning or ON/OFF control, easy-to-read LED display and two LED's for output status.

Two independent, precision 10-turn potentiometers enable accurate setpoint setting. Both the setpoints are independent of each other and can be set within the full span of the instrument. The standard output on second setpoints is ON/OFF only.

These instruments are calibrated for either one
of Type J/K Thermocouple or RTD. Other calibrations are available.
