The binary input board 23BE40 is used for the isolated input of up to 16 binary process signals. The input signals are scanned and processed with a time resolution of up to 1 ms.
The board is available in two versions (rubrics):
23BE40 R0011 for 110.... .125 V DC
23BE40 R0012 for 220.... .250 V DC
The input signals can be assigned to processing functions according to configuration rules.
The 23BE40 can process the following types of signals:
16 time-stamped single indications
8 time-stamped dual indications
2-step position information with 8 bits per step
8/16-bit digital measurement values
8/16 bit string information
16 pulse counters (max. 25 Hz)
These modules require the 560PSU40/41 power supply.
Features
All inputs are potentially isolated via optocouplers. If a common loop is required, this can be realized with the external short-circuit connector supplied.
Inputs 1 ... 8 have current sources for oxide film disconnection. These current sources are active within 10 ms of the input signal.
If the input signal changes more frequently than every 30 seconds, the on-time of the current sources is reduced.
Input currents of the 1.5 mA type are chopped to minimize power dissipation. As a result, the average input current is reduced to 0.4 mA.
The average input current and the oxide disconnect current remain constant over the input voltage range. The light emitting diodes are divided into two columns. the LEDs follow the input directly.
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.
