The BACnet MS/TP module with 4 S0 inputs to DIN EN 62053-31 class A was developed for decentralized 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.

The inputs can be scanned by means of standard objects via a BACnet client. The module is addressed and the bitrate is set by means of two address switches on the front.

Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
