Novus N322 J/K/T is a digital temperature controller for heating or cooling purposes with 2 independent setpoints. Operating range -50 to +1000 degrees Celsius with a K Type thermocouple, see below specification for J and T ranges. The output control can be refined with adjustable hysteresis and on/off time delays. With thermostatic control a gentle response can be achieved.
The N322 is a trusted product which will replace or upgrade the majority of manual or programmable thermostats used in industry.
With the RS485 version it is possible to integrate the device into a serial network. Using the Register Table below parameters such as setpoint (SV) and process value (PV) can be read from the devices.
MPN 8032204322
SIZE: 75 x 33 x 75 mm
PANEL CUTOUT: 70 x 29 mm (+0.5 -0.0 mm)
SUPPLY: 100~240 Vac (± 10 %)
INPUT: Thermocouple J/K/T
OUTPUTS:
OUT1: Relay SPDT; 1 HP 250 Vac / 1/3 HP 125 Vac (16 A Resistive)
OUT2: Relay: 3 A / 250 Vac, SPST
INPUT SENSOR: The sensor is chosen by the user at the time of purchase and is presented on the upper side of the equipment box.
The options are:
• Thermistor NTC, 10 kΩ @ 25 °C; Range: -50 to 120 °C (-58 to 248 °F); Accuracy:
0.6 °C (1.1 °F);
Maximum error in the interchangeability of original NTC sensors: 0.75 °C (1.35 °F).
This error can be eliminated through the offset parameter of the equipment.
Note: For the NTC thermistor option, the sensor comes with the equipment. Its
operating range is limited to -30 to +105 °C (-222 to +221 °F). It has cable of 3 meters
in length, 2 x 0.5 mm², and can be extended up to 200 meters.
• Pt100; Range: -50 to 300 °C (-58 to 572 °F); α= 0,00385; 3 wires; Accuracy: 0.7 °C (1.3°F); according to IEC-751 standards;
• Thermocouple type J; Range: 0 to 600 °C (32 to 1112 °F); Accuracy: 3 °C (5.4 °F);
• Thermocouple type K; Range -50 to 1000°C (-58 to 1832 °F); Accuracy: 3 °C (5.4 °F);
• Thermocouple type T; Range: -50 to 400 °C (-58 to 752 °F); Accuracy: 3 °C (5.4 °F);
