The Omron C200H-IA121 is an 8-point input module for Omron's C200H PLC system, providing eight digital input channels rated for 100–120 VAC. Each channel accepts a 100–120 VAC signal from field devices such as sensors or switches and conveys the respective on/off status to the PLC for real-time logic and control. The part number identifies the eight-point input module, intended to be used with the C200H family on the controller’s I/O backplane. Key specifications include eight input points and a 100–120 VAC input range; this module expands digital input capacity for industrial automation projects using the Omron C200H.
