The Omron C200H-IA122 is a standard AC digital input module belonging to the legacy SYSMAC C200H series of programmable logic controllers (PLCs). It is primarily designed to interface external high-voltage AC sensors, switches, or push-buttons with the PLC processor unit. While it is a legacy component that has been officially discontinued by the manufacturer, it remains widely used for maintaining existing industrial machinery and boasts backward compatibility with newer platforms like the Omron CS1 series.
