- ABB Advant OCS Advant AC500 PLC platform family
The core function of this module is to provide up to 24 freely definable digital input channels (C0 to C23). Users can program each channel as an input (DI) or output (DO) according to field requirements.
The module supports 24V DC input signals and 0.5A transistor output capability, making it widely applicable to medium to large-scale industrial automation scenarios. It can be used to accurately acquire input signals from buttons, proximity switches, etc., or directly drive actuators such as solenoid valves, contactors, and indicator lights.
The DC523 1SAP240500R0001 ABB Digital input/output module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Based on bidirectional level conversion, optical isolation, and intelligent channel monitoring technology, when the software configures the channel as an input (DI), the externally input 24V signal is converted to an internal logic level via an internal optocoupler. An adjustable digital filter (0.1ms to 32ms) eliminates contact bounce, and the final signal is sent to the main CPU image area via the I/O bus. When the channel is configured as an output (DO), the main CPU's control commands are sent via the bus to the driver chip inside the module, controlling the high-performance field-effect transistors (MOSFETs) to turn on or off at high speed, thereby precisely controlling the output of the 24V external process power supply (UP).
Flexible I/O Node Aggregation: Dynamically balances fluctuating input/output volumes on automated production lines, enabling a single module to handle any custom combination of sensors and actuators.
Pneumatic and Hydraulic Valve Control: Manages process valve assemblies by tracking limit switch status feedback while driving 24V DC directional control solenoid valves.
High-Speed Material Sorting: Captures rapid pulses from proximity tracking sensors using a dedicated internal high-speed counter and coordinates with fast-start pneumatic sorting doors.
Compact User Interface Integration: Connects directly to a local control panel to monitor manual inputs (buttons and selector switches) while powering local indicator lights or panel buzzers.
