Description

The M-Bus level converter BIALON MPW-120/IP lets you connect up to 120 M-Bus endpoints with a standard load of 1.5 mA each to an M-Bus Master via an Ethernet connection.
The M-Bus Master can be, e.g., a PC or an embedded controller. The level converter translates the signals from the M-Bus Master on the Ethernet interface to M-Bus signals.
Up to 250 MPW-60/IP can be connected to a PC-based M-Bus Master. The IP addresses on the level converter are assigned to virtual COM ports on the master. If needed, they can be grouped on the M-Bus Master via an additional program to use a single COM port. This means that an M-Bus Master program that only works with one COM port can communicate simultaneously with all M-Bus endpoints connected via the individual level converters.
The level converter has overload protection and is thus short-circuit protected. The trip threshold is 200 mA. Additionally, the M-Bus interface has overvoltage protection on the bus side.
The LEDs indicate the major operational and malfunction states, such as power supply, send or receive data, and bus overload.
The M-Bus BIALON MPW-120/IP level converter is available in two variants either with a 230 V AC or 24 V AC/DC power supply.
