CJ1W-PD022 CJ Series DC Power Supply Unit 19.6W 24V DC | Omron

The Original New Omron CJ1W-PD022 is a 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 19.6 W (5 V DC at 2.0 A, 24 V DC at 0.4 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 21.6–26.4 V DC input range, it delivers stable, maintenance-free operation for machine automation, material handling, and general factory control systems.
