OEM Modbus RTU Converter

The perfect connection to digital building management systems

Möhlenhoff’s RTU Modbus converter is a digitalisation solution for building management systems. It can also connect analogue thermal and/or motoric valve actuators to a digital RS485 system. Because compact valve actuators can be used, the Modbus converter is ideal in confined spaces.
