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.

Features
* True Proportional control, using linear time
   proportioning circuit.
* No calibration or set point droop.
* Easy access front panel adjustment for
   ON/OFF hysteresis or 'manual reset' in user
   specified instruments.
* <0.3⁰C indication drift.
* Built-in automatic cold junction compensation
   circuitry.
* Standard open sensor display and up scale
   break protection.
* Dimensions: 96H x 96W x 110D mm
                      74H x 74W x 110D mm
