Modbus Temperature and Humidity Sensors | RHR-MOD Modbus Room Humidity Sensor with Temperature

Modbus Room Humidity Sensor with Temperature

Datasheet (871kB)

RHR-MOD Modbus humidity sensors are designed to detect relative humidity and temperature in the room spaces. The Modbus humidity sensors have linear 0..10V signals outputs relating to humidity and temperature, and for optional light level. The units also have a digital input, a resistive input and two digital outputs. The RHR-MOD Modbus humidity sensors have built-in RS485 Modbus communication.

RHR-MOD Modbus humidity sensors can be installed on wall surface or on a wall mounting box in dry indoor environment. The RHR-MOD Modbus humidity sensors come with a number of options such as display, active setpoint, occupancy detection, lux level measurement, push button and additional digital/resistive input.

The RHR-MOD Modbus humidity sensors can also operate as humidity, temperature or light level controllers modulating analogue outputs of the sensor.
