ABB 23BE23 Datasheet Binary Inputs 16-Channel LEDs

Applications

The binary input module 23BE23 provides 16 current-isolated

inputs for up to 16 binary process signals. Scanning and pro

stopping of the inputs is performed with a high time resolution of

of 1 millisecond. The assignment of input signals to process functions

can be adjusted according to the configuration rules.

Module 23BE23 is capable of processing the following types of

signals or combinations of them.

- 16 single point messages with time stamp (SPI)

8 double-point messages with time stamp (DPI)

- 2 digital measurements of 8 bits each (DMI8)

One 16-bit digital measurement (DM16)

- 16 integrated totals (max. 120 Hz) (ITI)

- 2 step position information, 8 bits each (STI)

2 bit string inputs, 8 bits each (BSI8)

One 16-bit bit string input (BSI16)

One or a combination of these signal types

The module allows process voltages from 24 to 60 VDC. Light Emitting Diode

Signals are provided for all inputs. The module has a common return of every 8 inputs.

Characteristics

Binary Inputs

The inputs are electrically isolated by means of optocouplers.

The 8 inputs are constructed as a group with a common return. Inputs

The circuitry is designed to keep the input current constant with a current regulator 1 = pole.

The module has 16 LEDs ,which are used to indicate the signal status of the inputs.

The LEDs directly follow the input signal.

The maximum permissible frequency of the inverse pulse is 120 Hz.

Power supply input

The required power supply for the module is supplied to the baseboard via the RTL J560.

I/O Controller (I0C)

The microcontroller on the module handles all time-critical

tasks of the parameterized processing functions. Furthermore, it

communicates interactively with the RTU/O bus.

All configuration data and processing parameters are handled by the

communication unit via the RTU V0 bus.

The module is equipped with a bus connected to the RTU560 V0 backplane.

0 backplane.

The binary input unit can perform the following processing

functions for different types of signals.

-digital filtering to suppress contact bounce

-Suppression of oscillating signals caused by this process

-Validity check and suppression of intermediate input states

For dual indications

-Consistency check for all channels assigned to digital measurement

sured value or step position information.

-Incremental pulse phase addition formation

31-bit resolution register

-Copying of the integral total value into the freeze register

Data Saving

The module provides a data buffer for temporary storage of up to 50 event messages, including timestamps.

up to 50 event messages, including timestamps. These events are

stored in chronological order and are designated for transmission to the

Communication Unit (CMU).

During initialization and operation, the module performs a -test of BER.

test BER, and if a failure occurs, it is reported to the communications

unit. All fault conditions affecting the function of the module are

signaled as common faults by red LEDs. Failure of the module is detected by the communication unit.
