Digital Temperature Controller

Series 40 Digital 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-42A,
digital indicating temperature controller is designed for maximum versatility at an economical price. These instruments have standard features including a 5Amp SPDT relay with control output as time proportioning or ON/OFF control, an easy-to-read LED display and an LED indication for output status.
 
In these models, easy access front panel adjustment is available for ON/OFF hysteresis variation for ON / OFF control mode and 'manual reset' for time proportioning control, to stabilize process temperature at the set point.
 
These instruments are calibrated for either one of Tyep J/K Thermocouple or RTD. Other calibrations are available.
 
On specification, output to drive solid-state relay is available.
