The OMRON C200H-PS211 is a dedicated power supply unit designed for the C200H series programmable logic controller (PLC) expansion racks. This module provides regulated 24 VDC power to I/O modules mounted on backplanes, ensuring stable and reliable operation of connected field devices and control components. The C200H-PS211 is specifically intended for use in expansion I/O racks and mounts in the rightmost slot of the rack, delivering power to all modules installed on that backplane.
The C200H series supports a flexible system configuration where one CPU rack can be expanded with up to two expansion I/O racks. Additionally, multiple slave racks can be connected via optical or wired cable to a Remote I/O Master Module mounted on either the CPU rack or an expansion I/O rack, with up to five slave racks per CPU rack. The C200H-PS211 plays a critical role in these distributed configurations by providing local power to each expansion or slave rack.

The OMRON C200H-PS211 power supply unit is deployed in C200H-based PLC systems requiring I/O expansion beyond the capacity of a single rack. In large-scale manufacturing lines, multiple expansion racks are distributed throughout the production floor, each with its own C200H-PS211 providing local power to I/O modules near field devices.
The module is also used in systems with remote I/O configurations where slave racks are located up to significant distances from the main CPU rack, communicating via optical or wired cable. Typical applications include automotive assembly plants, material handling systems, packaging machinery lines, and process automation facilities where distributed control architectures reduce wiring costs and improve system organization.
