The N321R is a temperature controller dedicated to applications in refrigeration. The defrost cycle is accomplished by turning off the compressor at time intervals chosen by the user. Pt100, Pt1000 and thermistor sensors inputs are available. Adjust for ON and OFF durations. Auto defrost at programmable intervals. Manual Defrost key in the front panel. These temperature controllers are used to measure, indicator and control temperature in a wide range of applications! The front is IP65 and the output is a relay, SPDT.
Our Novus N321 temperature controllers are available in four different sensor inputs; Pt100, Pt1000, thermocouple J or thermister.
