M-bus supply converter MBRS-32

Main m-bus convertor MBRS-32

MBRS-32 is a microprocessor two-way full-duplex M-bus to RS-232С converter, with ability to supply maximum of 32 M-bus slave devices. 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 for short circuit in the output. In 2012 we have changed the enclosure, on the picture you can see old enclosure. Mounting of the unit is done on a standard М36 DIN-rail.
