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 www.cniacs.com 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.
