1. Description
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 baud rate is set by means of two address switches
on the front.
Suitable for decentralized mounting in serial sub-distributor.
