Metz Connect BMT-SI4
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.
Protocols: BACnet MSTP
Product Description
The inputs can be scanned by means of standard objects via a BACnet client. The BMT-SI4 IO module is addressed and the baud rate is set by means of two address switches on the front. Suitable for decentralised mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
