Product Overview

The Omron CJ1W-PA202 is a compact AC power supply module designed for CJ1 series programmable logic controller systems, providing reliable power for CPU units and I/O modules mounted on the CJ1 backplane. This power supply accepts 100-240V AC input voltage, supporting both 100V and 200V class power systems commonly found in industrial facilities worldwide. The CJ1W-PA202 delivers 50W output capacity, providing stable 5VDC power for the CJ1 backplane and all mounted modules. This capacity is suitable for typical CJ1 configurations with 8 to 16 modules, depending on the current consumption of each module. The module features a compact design that mounts directly to the CJ1 backplane, simplifying system installation and reducing panel space requirements. Built-in status LED indicators provide at-a-glance monitoring of power supply status, helping quickly identify power-related issues. The CJ1W-PA202 includes comprehensive protection features including overcurrent protection, overvoltage protection, and thermal shutdown, safeguarding both the power supply and connected modules from damage due to abnormal conditions. The module is designed for DIN rail mounting in control panels, with reliable screw terminal connections for input power wiring. Applications include powering CJ1 PLC configurations in machine control, process automation, material handling systems, and building automation installations.

FAQ for CJ1W-PA202

How many I/O units can this power supply support?
Depends on unit consumption. Typical CJ1W unit: 100-200mA at 5VDC. PA202 (5A) can power approximately 20-30 I/O units. Calculate total consumption before sizing.
Do I need external 24VDC for inputs/outputs?
Yes, PA202 provides 5VDC for backplane only. External 24VDC supply required for sensor power and output loads. Use separate 24VDC power supply.
What happens during power failure?
Hold-up time: 10ms minimum. PLC may continue running briefly. For critical applications, add UPS or use battery backup unit to maintain operation during brief outages.
Can I use DC input instead of AC?
No, PA202 is AC input only. For DC input, use CJ1W-PD022/PD025 DC power supply units (24VDC input).
