OEM Modbus RTU Converter

The communications interface for smart buildings

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.

OEM Modbus RTU Converter

Smart, digital and versatile

Different valve actuators are controlled by one register structure
Through-wiring of operating voltage and serial data bus in slave mode
Through-wired RS-485 inputs and outputs
Modbus RTU data protocol communication
1 Modbus address = 2 actuators and 2/4 sensors
Future bus/protocol changes possible without valve actuator replacement
Soon switchable to BACnet MS/TP
Remote maintenance of all valves
Reports on short circuits, malfunctioning valves or valve actuators
Valve-position monitoring
