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.
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
