ABB Binary Input Board 23BE50 for isolated input of 64 groups of 4 process signals
APPLICATIONS
The Binary Input Board 23BE50 is used for the isolated input of 64 process signals divided into 4 groups of up to 16 binary signals each.
The input signals are scanned and processed with a time resolution of up to 1 ms.
The input signals can be assigned to processing functions according to configurable rules. The board 23BE50 can process the following types of signals:
64 time-stamped single indications
32 time-stamped dual indications
8-step position information www.cniacs.com with 8 bits per step
8/16-bit digital measurements
8/16-bit string information
64 pulse counters (max. 120 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 external shorting connectors, which are included in the delivery.
Typical input current on the inputs is 1.5 mA.
There are 64 LEDs on the board to indicate the signal status. The LEDs are divided into two columns and follow the inputs directly.
The binary input board 23BE50 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
