The Viltrus MB Series M-Bus to Modbus converters provide a practical interface between wired M-Bus meters and Modbus RTU monitoring and building-management systems. Available in MB-10, MB-50, MB-80, MB-100 and MB-250 versions, the range supports networks of up to 250 M-Bus devices, with RS485 or RS232 communication options.
Reliable integration of M-Bus heat, water and energy meters with Modbus-based control and monitoring systems.
The Viltrus MB converter range is designed to collect information from wired M-Bus metering networks and make it available to equipment communicating via Modbus RTU. This provides an integration route for compatible meters in commercial buildings, plant rooms, communal heating installations and other multi-meter applications.
Five models are available to suit different network sizes. Each model can be specified with an RS485 or RS232 interface, allowing the converter to be matched to the receiving system. The devices feature DIN-rail mounting, galvanic isolation and protection against M-Bus line short circuits.
Select a converter according to the number of M-Bus devices on the network and the serial interface required by the receiving Modbus equipment.
| Model | Maximum M-Bus devices | Interface options |
|---|---|---|
| MB-10 | 10 | RS485 / RS232 |
| MB-50 | 50 | RS485 / RS232 |
| MB-80 | 80 | RS485 / RS232 |
| MB-100 | 100 | RS485 / RS232 |
| MB-250 | 250 | RS485 / RS232 |
The model number indicates the maximum supported M-Bus device count. Check the total M-Bus load and compatibility of the connected meters before specifying the converter.
M-Bus is widely used for reading heat, water and other utility meters, whereas Modbus RTU is commonly used by controllers and building-management equipment. The Viltrus MB series provides an interface between these systems, reducing the need for separate manual meter-reading arrangements.
The MB range is intended for serial Modbus RTU communication. Do not confuse RS485/RS232 versions with a native Modbus TCP/Ethernet converter. Confirm the required meter data points, register mapping and commissioning settings for your application.
Note: The manufacturer's overview also mentions baud rates up to 38,400 bit/s, while its technical specification table states 300–9,600 baud for data transfer. Confirm the required serial settings against the specific model datasheet before ordering.
Contact Stockshed Metering with the number and type of M-Bus meters, the required RS485 or RS232 connection and details of the Modbus RTU monitoring system. We can help identify a suitable MB converter for your installation.
