The N32xRHT is a family of relative humidity and temperature electronic controllers. The N322RHT has two relay outputs and the N323RHT has three relay outputs.  The outputs may be independently configured for either on/off control or as an alarm output. The control outputs can operate with either reverse control action (heating or humidification) or direct control action (cooling or dehumidification). The alarm outputs may be either high alarm, low alarm or set to trigger inside or outside a temperature range.  The third output of the NR323RHT may  be set as an independent timer.

The N32xRHT works with an external humidity/temperature probe. The sensor of the probe is protected by a polyamide capsule and is available with either a three or six meter PVC insulated cable.

The  N32xRH display alternately shows the temperature and humidity. Time between those indications is configurable by the user.

Depending on the model selected, the  controller may be powered by either 100 to 240 Vac or 12 to 24 Vac/dc.  It is also available with optional RS485 communications with Modbus protocol.
