Easy, Direct Connection of Energy and Consumption Meters – With the M-Bus Master

Reduce costs, simplify installation, and save space: The new 753-649 M-Bus Master Module directly connects up to 40 M-Bus devices to the I/O system to capture consumption data – without external gateways and level inverters.

Intelligent energy management begins with separate collection of heat, water, electricity and gas consumption. Therefore, it is the focus of private and commercial users to measure energy consumption – first and foremost in the area of building automation.

The I/O system with an M-Bus Master module (Meter-Bus) is the right solution to handle energy and consumption data: Depending on the WAGO controller, consumption data can be transmitted flexibly on the control system's existing fieldbus protocol. By doing so, you avoid additional cabling for the building information. Software can be used to easily ready the data via the ETHERNET interface.

The M-Bus is inherently a cost-effective fieldbus for transmitting energy consumption data in accordance with EN 13757. Reduce additional costs with WAGO's M-Bus Master Module: The module is very space-saving compared to comparable solutions, thus reducing wiring overhead.

The M-Bus is used to read energy consumption data from power meters, heat meters, gas meters, water meters and various sensors and actuators from different manufacturers. As an efficient system for measuring consumption data, the M-Bus is often used in the area of building control systems.

The M-Bus system, based on a master/slave communication model, can be operated as a line, star or tree topology. The master powers the serial bus and processes the data of the M-Bus slaves (measurement devices). A WAGO Controller with the M-Bus, which communicates with bus components via a 2-wire bus, can assume the role of the master. Up to 40 slaves can be connected per module. The M-Bus transmits data at speeds of 300 to 9600 bps. Regular type J-Y(St)Y N x 2 x 0.8 mm telephone cable, for example, can be used as the M-Bus cabling.
