Omron Corporation C200H-AD003 Analog Input Module

The Omron C200H-AD003 Analog Input Module is an 8-channel A/D conversion module designed for Omron C200H PLC systems, installed in control racks to convert analog sensor signals into digital data for PLC processing. It supports both current and voltage inputs, including 4–20 mA and 1–5 V, 0–10 V, and -10 to 10 V, with an approximate conversion time of 1 ms per channel. Max input limits are ±15 V and ±30 mA, and the unit provides photocoupler isolation between inputs and the PLC to help protect the control system. Power consumption is around 100 mA at 5 V or 26 V DC, and it uses a 28-point terminal block with M3 screws for wiring. Compatibility spans C200H, C200HS, C200HX, C200HG, and C200HE PLCs, making it suitable for process control, temperature monitoring, pressure systems, and manufacturing-line signal acquisition where stable, configurable analog input is required. The module is discontinued, with replacements routed through the CS/CJ series, and common substitutes include CS1W-AD081-V1, CJ1W-AD081-V1, and C200H-AD002.
