Product Overview
The Omron CJ1W-CPU22 (commonly listed by its CPU module code, CJ1M-CPU22) is a CJ-series CPU unit with ten built-in DC inputs and six built-in transistor outputs on the CPU slice itself. It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
Programmed with CX-Programmer on USB or RS-232C 0.1 microsecond LD execution, 32K-word data memory CJ-series built-in I/O CPU, 10K-step program capacity 0.1 microsecond LD execution, 32K-word data memory
CJ-series built-in I/O CPU, 10K-step program capacity 0.1 microsecond LD execution, 32K-word data memory
If the application needs remote I/O over EtherNet/IP, pick a CJ2M-CPU33 or higher instead.
Key Features
- CJ-series built-in I/O CPU, 10K-step program capacity
- 0.1 microsecond LD execution, 32K-word data memory
- Compatible with CJ1W-PA202 / CJ1W-PD025 power supply
- Programmed with CX-Programmer on USB or RS-232C
- SKU: CJ1W-CPU22
- Series: CJ-series built-in I/O CPU
- I/O: 320 points
Best-Fit Applications
- Index tables that need ten inputs for home and limit sensors on the CPU
- Material-handling conveyors with sensors and motor starters on the same PLC
- Filling and capping lines where the CPU also drives solenoid valves directly
Buying Checklist
- Choose CJ2M-CPU33 when the application needs EtherNet/IP and 20K steps.
- Choose CJ1M-CPU11 for the same 5K-step base CPU without built-in I/O.
- Choose CJ1W-PA202 for 100-240 VAC supply or CJ1W-PD025 for 24 VDC supply.

FAQ for CJ1W-CPU22
What is the difference between CJ1W-CPU22 and CJ1M-CPU22?
The two names refer to the same CPU module. CJ1W is the rack-mount prefix used in some catalogue listings; the official Omron SKU is CJ1M-CPU22. Either way, the module drops onto any CJ-series rack and provides 10 built-in inputs, 6 built-in outputs, 10K-step program, and 32K data words.
Can the CJ1W-CPU22 sit on an expansion rack?
No. The CJ1M-CPU22 supports a single CPU rack with up to ten CJ1W I/O modules. For machines that need remote racks, move up to a CJ1M-CPU13 / CPU23 (with expansion) or a CJ2-series CPU. Up to three expansion racks are allowed on those higher CJ1M and CJ2 CPUs.
Which power supply pairs with the CJ1W-CPU22?
Either CJ1W-PA202 (14 W, 100-240 VAC) or CJ1W-PD025 (DC supply for 24 VDC cabinets) is the standard choice. The PA202 / PD025 sits to the left of the CPU and powers the whole rack. For larger racks that need 25 W, choose the CJ1W-PA205R with the RUN output contact.
