The Omron C200HW-PA209R PLC Power Supply Unit converts a 100 to 240 VAC input into 5 VDC at 9 A for powering compatible modules within C200H-series Programmable Logic Controller systems. Its higher output capacity supports rack-based control architectures where multiple PLC modules require a common regulated DC power source. The unit provides the power layer needed for stable operation of connected controller components in industrial machine and factory automation systems. Its configuration supports larger automation installations with greater rack power requirements. The C200HW-PA209R supports the C200HW control architecture and forms part of the high-capacity PLC power supply range associated with Omron industrial control systems.
