The Novus N322 Thermostat is a budget priced On-Off temperature controller with industrial level reliability. This model includes an NTC thermistor, has an RS-485 Modbus communication interface and is powered from 230 VAC. Other models don't have RS-485, are 12 to 24 V AC/DC powered or take PT100 input or J, K and T type thermocouple input.

The NTC thermistor models are provided with a waterproof stainless steel NTC Thermistor probe and 2 metre long cable to get you up and running immediately. This cable can be extended to 50 metres.

The N322 thermostats have two relay outputs which can be configured for heating or cooling or a number of different alarm modes and are easily configured by the front panel buttons and display.

The temperature and status of relays are shown on the LED Display. Great for aquariums, home brewing, ovens, fridges, greenhouses and many other applications.

RS-485 Modbus communications allows the temperature, output status and all configuration variables to be accessed from a PLC, computer or building management system.
