The Omron C200HW-PA204C PLC Power Supply Unit converts a 100 to 240 VAC input into 5 VDC at 4 A for powering compatible modules within C200H-series Programmable Logic Controller systems. It includes a battery connector that supports the backup architecture associated with the controller system. The regulated 5 VDC output provides operating power for compatible rack modules and other control components installed within the PLC architecture. This allows the power supply to serve as the electrical foundation for rack-based machine and process-control configurations. The C200HW-PA204C supports the C200HW control architecture and belongs to the PLC power supply range associated with Omron machine automation.
