14/5/2019 Do you plan to include M-Bus meters into your project and you search for a way to connect them to UniPi controllers? Our brand-new RS485/M-Bus converter is the solution! 

The M-Bus (Meter-Bus) industrial communication protocol was created as a method of reliable data collection from various quantity meters such as energy meters, gas meters, water flow meters, calorimeters etc. Among its most distinctive features is its high resilience towards interference and length of the bus that can reach up to several hundred meters.

As UniPi programmable logic controllers do not feature the direct M-Bus communication yet, we introduced a compact RS485/M-Bus converter to enable communication between UniPi controllers and M-Bus modules.  

The converter can communicate with up to four M-Bus slave devices. The converted data are then sent via RS485 interface into RS485-compatible device connected to the converter, such as UniPi controller; this will allow you to use the data for other purposes such as HVAC control, data upload into a database or data visualisation using SCADA interface. The converter itself features a DIN-rail mount and LED for operation and error indication. 

RS485toMBus-4M converter

- up to 4 M-Bus slave devices
- galvanically isolated M-Bus interface
- 300 - 9600 bps transmission speed
- IP20 protection
- DIN rail mount (35 mm)
- LED indication of operation and error state
