N323-PT100-485 Thermostat Controller with PT100 Sensor input and RS-485, 24 VAC

The Novus N323 Thermostat is a budget priced On-Off temperature controller with industrial level reliability. This model accepts a PT100 RTD sensor and has an RS-485 Modbus communication interface and is powered from 24 VAC or 24VDC.

The N323 thermostats have three 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.

Features:

  • PT100 sensor input
  • IP65 when mounted in panel
  • Fully configurable
  • Heating or cooling actions
  • Configurable hysteresis
  • Configurable start-up delay to reduce inrush current when using multiple controllers
  • Configurable minimum on and off times to extend compressor or heater life
  • Over /under temperature and in-bound / out-of-band alarms
  • Optional multi-level password protection
