M-Bus Temperature and Humidity Sensor

Datasheet (895kB)

RHR-MBUS M-Bus Humidity sensors are designed to detect relative humidity and temperature in the room spaces and have built-in M-Bus (Meter Bus) EN1434-3 communication interface. The M-Bus humidity sensor uses 2% accurate sensing element. The sensors have programmable linear 0..10V signals outputs. The RHR-MBUS M-Bus humidity sensors have also a built-in digital and a resistive input (e.g. for external temperature measurement), and two additional digital outputs as standard, so the modules can be also used as intelligent I/Os.

The RHR-MBUS M-Bus humidity sensors can be installed on wall surface or on a wall mounting box in dry indoor environment. The RHR M-Bus humidity sensors come with a number of additional options such as display, active setpoint using two push buttons, push buttons for extensions and additional digital and resistive inputs.

The RHR -MBUS M-Bus humidity sensors can also operate as temperature or humidity controllers modulating analogue outputs, or switching the digital output on based on the setpoints making them ideal for advanced control applications. With push button option the users can override the control output fully open e.g. in demand based applications.
