Applications

The binary input board 23BE40 performs the following processing functions for different types of signals:

 Digital filtering to suppress contact jumping

 Suppression of technically induced chattering signals

 Intermediate position suppression and double indication monitoring

 Consistency check of all binary input channels assigned to digital measurement values

The 23BE40 has a buffer for temporarily storing 50 time-stamped event messages in chronological order,

designated for transmission to the communication unit.

The board’s microcontroller handles all time-critical tasks for the parameterized processing functions. In

addition, it communicates interactively with the RTU560 system bus.

All configuration data and processing parameters are transmitted via the RTU560 system bus.

All configuration data and processing parameters are loaded from the communication unit via the

RTU560 bus.

The board is equipped with a serial interface to the RTU560 system bus.

During initialization and operation, the board performs a series of tests. If a fault occurs, it is reported to

the communication unit.

All fault conditions affecting the board’s functionality are indicated as general fault signals by means of

light emitting diodes (ST). Faults in the board are detected by the communication unit.
