MBRS

MBRS-250 is a microprocessor two-way full-duplex M-bus to RS-232С converter, with ability to supply maximum of 250 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. Mounting of the unit is done on a standard М36 DIN-rail.
