Digital Temperature Controller

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' Manufacturers Of Digital  Temperature Controller (Model DC-42A) 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.

Digital Temperature Controller Features :-
