M-bus repeater MBRP-250

M-bus repeater MBRP-250

MBRP-250 is a microprocessor two-way full-duplex M-bus to M-bus converter, with ability to expand existing network with up to 250 additional slave devices. It is intended to expand and segment given network up to 500 m-bus devices. It is protected for short circuit in the output. Mounting of the unit is done on a standard М36 DIN-rail.
