The Metz Connect BMT-SI4 BACnet MS/TP IO module with 4 S0 inputs to DIN EN 62053-31 class A was developed for decentralised switching tasks.
It is suitable for counting S0 counter pulses. This allows very good integration of the module into an energy controlling system. In case of a power failure, the last counter readings are saved.
