BMT-SI4 BACNET MS/TP - BACnet MS/TP module with 4 S0 inputs

The BACnet MS/TP module with 4 S0 inputs according to DIN EN 62053-31 class A has been developed for decentralized switching tasks. 
It is suitable for counting S0 meter pulses. This allows optimal integration of the module into an energy management system. 
In case of power failure, the last meter readings are saved. 
The inputs can be scanned via standard objects by a BACnet client. 
The module is addressed and the baud rate is set using two address switches on the front. 
Suitable for decentralized mounting on DIN rail TH35 according to IEC 60715 in electrical distribution panels.
