Omron C200H-CPU02 Programmable Controller CPU Module is the central processing unit for Omron C200H PLC systems, executing control logic in industrial automation environments. This PLC CPU module provides approximately 8K steps of program capacity (model dependent) with built-in data memory and uses cyclic scan execution to manage machine control, sequencing, and process automation tasks, operating from 0°C to +55°C. It mounts in a PLC rack and is powered through a separate power supply module, with a peripheral port for interface-unit communication and LED indicators (RUN, ERR/ALM) to show status. Compatible with C200H series I/O and special modules, it is commonly used in control panels, manufacturing lines, and legacy automation setups requiring reliable PLC operation, with common replacements including the C200H-CPU01, C200H-CPU03, and CJ1M-CPU11.
