Omron ANALOG INPUT MODULE C200H-AD002

The Omron C200H-AD002 is a high-performance 8-point analog input module designed for the SYSMAC C200H and C200HS PLC series. It remains a staple in legacy industrial systems due to its reliability and built-in signal processing functions.

Summery:

For current inputs (4–20mA), you must bridge the voltage input terminal and the current input terminal for that specific point. All inputs are non-isolated from each other but are isolated from the PLC internal circuitry. Omron recommends the CS1 series (using the CS1W-AD081-V1 module) or the modern NX/NJ series for EtherCAT-based architectures.
