Omron Corporation C200H-ID212 Digital Input Module

The Omron C200H-ID212 Digital Input Module is a 16‑channel, 24 VDC input interface for Omron’s C200H series that captures field signals from sensors and switches and feeds them to the PLC backplane. It mounts in a C200H rack, is powered from the PLC backplane, and provides optical isolation between inputs and the backplane to improve noise immunity in harsh industrial environments. Each input draws about 7 mA and can be configured as sink or source depending on wiring, with a typical response time of 10 ms and LED indicators per point to show status. The operating temperature range is 0°C to 55°C, making it suitable for factory floors, and it supports reliable digital signal monitoring in applications such as manufacturing lines, conveyors, packaging machines, and other automated equipment, where precise, stable input detection is essential for machine control, assembly lines, material handling, and process automation. Common replacements include Omron C200H-ID211, CJ1W-ID211, and Siemens 6ES7321-1BL00-0AA0.
