Industrial M-Bus to Modbus Converters

In this section of our shop, you will find a wide range of M-Bus to Modbus converters that allow seamless integration of M-Bus meters with Modbus-based control systems. These devices support both Modbus TCP (Ethernet) and Modbus RTU (RS-485/RS-232), enabling flexible communication with PLCs, building automation systems (BMS), HVAC controllers, SCADA systems, and energy management platforms. Whether you are integrating gas, water, electricity, or thermal energy meters — our converters offer stable, scalable and easy-to-deploy solutions for industrial environments.

What Makes Our M-Bus to Modbus Converters Stand Out?

Each converter in our lineup is designed for use in demanding industrial applications. Devices are mounted on standard DIN rails, built with EMC-resistant enclosures, and capable of operating in extreme temperatures ranging from -40°C to +85°C. Most models are housed in compact metal enclosures, making them ideal for installation in electrical cabinets, junction boxes, or remote field enclosures.

Our converters support communication with all M-Bus-compliant meters, including popular manufacturers such as Kamstrup, BMeters, Apator, Schrack, Astat and many others. They act as Modbus slaves, making the meter data directly accessible from any SCADA or controller using Modbus read commands.

Flexible Connectivity Options

The converters are equipped with the following communication ports:

• M-Bus (master) – screw terminals for direct connection of up to 250 M-Bus meters
• RS-485 / RS-232 – for Modbus RTU communication with serial devices
• Ethernet (RJ45) – for Modbus TCP communication and web-based configuration

Depending on the model, the converters support 20, 40, 80, 160, or 250 M-Bus devices. The number of supported meters determines the power requirements of the device, with typical consumption ranging from 4W to 30W. All devices comply with M-Bus transmission standards, including max bus length of 350 meters (JYStY N*2*0.8mm cable), baud rates between 300 and 9600 bps, and bus voltage levels.

Reliable and Configurable M-Bus Integration

Each M-Bus to Modbus converter comes bundled with free configuration software. The included Scan & Decode tool allows you to scan the entire M-Bus network, automatically detect connected meters, and map meter variables to Modbus registers. It also supports mathematical transformations (e.g., multiplying/dividing values for scaling) and manual register mapping for custom integration.

For applications that require extending the length of the M-Bus or isolating separate meter groups, we also offer a full line of M-Bus repeaters and isolators. These devices ensure reliable operation even in large or complex meter networks.
