Product: ABB 23BE21 1KGT004900R5012 Binary Input Board

Description

The binary input module 23BE21 provides 16 galvanic isolated inputs for up to 16 binary process signals. Scanning and processing of the inputs are executed with the high time resolution of 1 ms.

The allocation of an input signal to the processing functions can be done according to the rules of configuration.

The module allows process voltages from 24 to 60 V DC. LED signaling is available for all inputs. The module has a common return per 8 inputs.

The module 23BE23 is able to process the following types of signals or a combination of them:

– 16 single point information with time stamp (SPI)

– 8 double point information with time stamp (DPI)
– 2 digital measured values each with 8 bit (DMI8)
– 1 digital measured value with 16 bit (DMI16)
– 16 integrated totals (max. 120 Hz) (ITI)
– 2 step position information each with 8 bit (STI)
– 2 bitstring input each with 8 bit (BSI8)
– 1 bitstring input with 16 bit (BSI16)
– or combinations of this signal types

The micro-controller on the module processes all time critical tasks of the parameterized processing functions. Moreover it carries out the interactive communication with the RTU I/O bus.

All configuration data and processing parameters are loaded by the communication unit via the RTU I/O bus.
