Binary Input 23BE40
Application
The binary input board 23BE40 is used for the iso-lated input of up to 16 binary process signals. Scan-ning and processing of the inputs are executed with the high time resolution of 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 allocation of an input signal to the processing functions can be done according to the rules of con-figuration. The 23BE40 can process the following types of signals:
∙ 16 single indications with time stamp ∙ 8 double indications with time stamp
∙ 2 step position information each with 8 bit ∙ 8/16 bit digital measured value(s) ∙ 8/16 bit String Information
∙
16 pulse counters (max. 25Hz)
Power supply 560PSU40/ 41 is needed to feed this modules.
Characteristics
All inputs are potentially isolated by means of opto-couplers. If a common return is necessary, it can be realized by the external short circuit connectors in-cluded in the delivery.
The inputs 1 ... 8 feature current sources for oxide film breaking. These current sources are active for 10 ms after applying an input signal. If the input signals change more often than every 30 seconds, then the on-time of the current sources will be re-duced.
The input current of type 1.5 mA is chopped for the
reduction of the power dissipation. Thus, the average input current is reduced to 0.4 mA. The average input current and the oxide film breaking current are kept constant over the input voltage range.
The board has 16 light emitting diodes to indicate the signal-state. The LED’s are organized in two co l-umns. The LED’s follows directly the input.

The binary input board 23BE40 can execute the following processing functions for the different types of signals:
∙ Digital filtering to suppress contact bounce ∙ Suppression of technologically caused chat-tering signals
∙ Intermediate position suppression and mon-itoring for double indications
∙
Consistency check for all binary input chan-nels allocated to digital measured values
The 23BE40 has a buffer which allows the temporary storage of 50 time-stamped event messages in chronological order designated for transmission to the communication unit.
The board’s micro-controller processes all time-critical tasks of the parameterized processing func-tions. Moreover, it carries out the interactive commu-nication with the RTU560 system bus. All configura-tion 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 carries out a number of tests. If a fault occurs, it is reported to the communication unit. All fault conditions impair-ing the function of the board are displayed as com-mon fault signal with a light emitting diode (ST). A failure of the board is detected by the communication unit.
