ABB 23BA20 GSNE000700R5312 Binary Output Board

Binary output functions: The 23BA20 board provides digital output signals for controlling external devices that operate in binary states, such as relays or solenoids.

Outputs: The 23BA20 board typically provides multiple output channels (e.g. 8 or 16 channels), depending on the configuration, to control various devices in an automation system.

Activation: The I/O microcontroller (EAP Input Output Processor) activates any output forced by the VAP of the CMU (CMU = Communication Unit) by issuing an output request. The EAP controls the duration of the pulse output by means of a loaded pulse length time value.

Output monitoring and supervision: The EAP checks and monitors any output by means of different test and supervision functions: x Reading back the output mode before activating the output x Monitoring of the 24 V DC from the backplane bus to the switching output relays during active output x Pulse duration is controlled by the EAP x Any detected error is indicated by an LED.
