Modbus Room Temperature Sensors | TEHR-MB TEHR-MB Modbus Room Sensor and AO

TEHR-MB room transmitters measure temperature in wide range of applications ann can be used as Zone Output device. The TEHR-MB transmitters come with integrated Modbus RTU RS-485 communication interface allowing savings in the BMS system IO-requirements and providing accurate measurements.

The TEHR-MB transmitters have 2 x 0..10Vdc outputs; one for the local 0..10Vdc temperature signal and one for 0..10Vdc zone control. The zone control output level can be set over Modbus or the TEHR-MB built-in controller logic can modulate the output based on setpoints and room temperature.

The transmitters are available with (-N models) or without display.

Required Tools

HDH-C configuration tool is required to alter the default Modbus address and baud rate.
