Pulse counter with m-bus MBSS-2/4/6/8

Pulse counter with m-bus MBSS-x

MBSS-2/4/6/8 are microcontroller pulse counters with m-bus interface. Their purpose is to connect in m-bus network devices, which do not have m-bus (usually water- and heat- meters with pulse output). MBSS-2/4/6/8 have embedded real time clock and backup battery, but no display and keyboard are provided. Mounted on a standard М36 DIN-rail.

General information

МBSS-2/4/6/8 are n-input pulse counters, intended to connect in m-bus network tax instruments or other devices, which do not have m-bus interface, but pulse outputs. One MBSS-2/4/6/8 can connect maximum of 2/4/6/8 devices with pulse output to m-bus network. They are double powered - normally power supply is from the network, but if network failed for some reason, they switch to internal battery powered supply. This backup battery assures minimum 96h work time w/o external power supply. We also offer as an option additional battery, which will give minimum 90 days work time for the device. When network voltage is up again, the battery is recharged. to full capacity. When a data readout occurred, MBSS also sends battery status, so the additional batteries can be changed before they die.
