CJ1W-PD025 CJ Series DC Power Supply Unit 25W 24V DC | Omron

The Original New Omron CJ1W-PD025 is a 25 W DC power supply unit for the SYSMAC CJ series programmable logic controller (PLC) platform, converting 24 V DC input into stable 5 V DC and 24 V DC outputs for the CPU rack and connected I/O modules. With a total output capacity of 25 W (5 V DC at 5.0 A, 24 V DC at 0.8 A), this unit provides reliable power for CJ-series CPU units, I/O modules, and Special I/O Units in DC-powered control cabinets. The unit mounts to the left of the CPU in CJ-series racks and supports DIN rail or panel mounting. Designed with overcurrent protection and a wide 19.2–28.8 V DC input range (±20%), it delivers stable, maintenance-free operation for machine automation, material handling, and general factory control systems. This unit cannot be used with the Machine Automation Controller NJ-series.
