Omron C120-IM213 Input Module is a digital input expansion module for Omron C120 PLC systems (also cataloged as 3G2A6-IM213). It provides dedicated input points to read signals from external devices such as sensors, pushbuttons, and limit switches, translating physical on/off states into the controller for logic and sequencing. Used to extend a C120 system’s I/O in automation projects, it supports common applications like machine control, process monitoring, and line automation by letting the controller respond to real-time input conditions.
