MBU-250 is a full-duplex M-bus converter with several interfaces. It can supply up to 250 m-bus slave devices and has RS-232, RS-485 and USB interfaces.
It also has M-Bus slave input and can be used as an M-Bus repeater in larger networks. It is intended for use in housing constructions and industrial buildings, mainly for distance reading of tax instruments or different types of sensors. It is protected from short circuits in the output. Mounting of the unit is done on a standard М36 DIN rail.
