MBus to RS485 converters to read M-Bus meters through RS485

Industrial MBus to RS485 Converters

MBus to RS485 converters are reliable and efficient devices designed to integrate utility meters with RS-485-based automation systems. These converters serve as bridges between M-Bus (Meter-Bus) slave devices and supervisory equipment using the RS-485 serial interface. They are ideal for remote meter reading, industrial automation, and smart building infrastructure, providing a cost-effective way to collect and transmit consumption data from distributed metering points.

The M-Bus protocol is widely used for communication with heat meters, water meters, electricity meters, and gas meters. A MBus RS485 converter enables integration of these devices into centralized control systems that rely on RS-485 communication, allowing efficient data aggregation and monitoring. With just a single RS-485 port, users can connect an entire M-Bus network and access real-time consumption information via SCADA, BMS, or industrial PLC systems.

Reliable MBus RS485 Solutions for Industrial Applications

Our MBus to RS485 converters are designed for demanding applications where data integrity and signal reliability are critical. RS-485 is a differential communication standard that supports long-distance transmission — up to 1200 meters — and multiple device connections on a single bus. This makes it an excellent choice for distributed metering systems in energy, water, or heating networks. Depending on the model, each converter can support from 20 up to 250 M-Bus slave devices, allowing scalable deployment and flexible system expansion.

All converters in our range are housed in compact, DIN rail mountable enclosures designed for use in industrial panels, cabinets, and field installations. With a wide operating temperature range from -40°C to +85°C, these devices are suitable for both indoor and outdoor use. They feature M-Bus master interfaces and RS-485 communication terminals, and many models offer configurable transmission settings such as baud rate, line termination, and master/slave mode selection.

Seamless Integration with SCADA, BMS, and Monitoring Platforms

MBus RS485 gateways are fully compatible with popular industrial protocols and software used in supervisory control (SCADA), building management systems (BMS), and PLC-based automation. These converters allow utilities and facility managers to integrate metering data directly into their control platforms, enabling real-time analysis, reporting, and alarms. The RS-485 interface ensures compatibility with most industrial devices, including data loggers, controllers, and remote monitoring equipment.

Installation is straightforward. Each device includes free configuration software that allows users to set communication parameters, address ranges, bus behavior, and diagnostic settings. Some models also include an Ethernet port for easy local configuration via a web interface. Diagnostic LEDs help visualize the status of power, M-Bus load, and RS-485 communication, making it easier to identify any issues during commissioning and operation.

By choosing a MBus to RS485 converter from our selection, you gain access to a proven technology for meter data communication in industrial, commercial, and utility environments. Our converters are used across sectors such as district heating, electrical distribution, smart water systems, and energy monitoring. They are also widely implemented in public buildings, factories, and logistics centers as part of broader automation frameworks.
