The N322 temperature controller is used for heating and cooling with 2 independent setpoints. The second setpoint can be relative to the first, with a delay between stage activations. It has one 10 A relay and one 3 A relay, and an input for Pt1000, NTC thermistor, PTC or type J (FeCo) thermocouples with sensor offset adjustment.
– Sensors: Pt100 (-50 to 300 °C), Pt1000 (-200 to 530 °C), J thermocouple (0 to 600 °C) or thermistor (-30 to +105 °C)
– Front protection: IP65
– Output: 1 control relay (SPDT: 1 HP 250 Vac / 1/3 HP 125 Vac (16 A resistive)) and 1 alarm relay (SPST-NO: 3 A / 250 Vac)
– Resolution: 0.1 °C between -19.9 and 199.9 °C
– Accuracy: ± 0.5 °C / °F ±1 digit (Pt100 / Pt1000 / thermistor) and ±2 °C for thermocouple
– Adjustable hysteresis
– Adjustable offset
– Sampling: 1.5 times per second
– Operating temperature: 0 to 50 °C
– Power supply: 100-240 Vac/dc (internal) or 12-30 Vdc/ac
– RS485 communication with Modbus RTU protocol (optional)
– Dimensions: 75 x 33 x 75 mm
