CJ1W-PA205R Power Supply Unit 25W 100-240VAC with RUN Output | Omron

The Original New Omron CJ1W-PA205R is a 25W AC power supply unit for the SYSMAC CJ series programmable logic controller (PLC) platform. It converts 100-240 VAC input to 5 VDC and 24 VDC outputs, providing reliable power to the CPU rack and connected I/O modules. Equipped with a SPST-NO relay RUN output that closes when the CPU is in RUN or MONITOR mode, this power supply enables external monitoring of PLC operation status for safety interlock and emergency stop circuits. The unit mounts to the left of the CPU in CJ-series racks and supports DIN rail or panel mounting. Designed with overcurrent and overvoltage protection, it delivers stable, maintenance-free operation for machine automation, material handling, and general factory control systems.
