Product Information
Full details
This Omron Power Supply Unit (CJ1W-PA205R) is designed for industrial automation applications, specifically for powering CJ series PLC systems and their expansion modules. It provides a stable 5 VDC output from a wide 100-240 VAC input range, ideal for robust control environments. A key benefit is its dedicated RUN output signal for monitoring operational status. However, its compatibility is limited to CJ series PLCs, requiring careful system integration.

FAQs
What is the input voltage range for this power supply?
The Omron CJ1W-PA205R accepts a wide input voltage range of 100-240 VAC.
What is the output voltage and current capacity?
It provides a stable 5 VDC output with a maximum capacity of 5 Amperes (5A).
What does the RUN output signal indicate?
The RUN output signal indicates the operational status of the power supply. It confirms that the power supply is functioning correctly and providing stable output power.
Is this power supply compatible with other PLC series besides CJ?
This specific model, CJ1W-PA205R, is designed for Omron CJ series PLC systems, including the CJ1M series. Compatibility with other PLC series is not guaranteed.
What is the maximum operating temperature?
The unit can operate reliably in ambient temperatures up to +55°C.
What are the physical dimensions of the unit?
The dimensions are 81.6 mm (width) x 90 mm (height) x 80 mm (depth).
How should I clean the unit?
Ensure the unit is powered off. Use a soft, dry cloth or compressed air to remove dust from ventilation slots and the casing. Avoid using liquids or solvents.
Troubleshooting
Power supply unit does not power on
Verify input voltage (100-240 VAC) is correctly connected to the power terminals. Check main circuit breaker and ensure local power is active. Confirm wiring integrity.
PLC system is not receiving 5VDC output
Check the 5 VDC output connections to the PLC backplane. Measure the output voltage directly at the unit's terminals using a multimeter. Ensure the total load does not exceed the 5A capacity.
RUN output signal is off or erratic
Confirm the RUN output terminal is correctly wired to the monitoring circuit. Check if the input voltage is within the acceptable range (100-240 VAC). If the unit is operating normally and the RUN signal is still off, the unit may require service.
Overheating or shutdown
Ensure ventilation slots are clear of obstructions. Verify ambient operating temperature is within the specified limits (up to +55°C). Reduce the load if it is consistently near the 5A maximum.
Pros and Cons
Pros
- Wide input voltage range (100-240 VAC) for global compatibility.
- Provides a stable 5 VDC output sufficient for most CJ series PLC configurations.
- Includes a RUN output signal for crucial operational status monitoring.
- Compact dimensions for space-constrained control cabinets.
- Designed for robust industrial environments with a high operating temperature limit.
Cons
- Limited compatibility, primarily for Omron CJ series PLCs.
- Output current of 5A may be insufficient for extremely large or power-hungry expansion module configurations.
- Requires specific knowledge of Omron PLC system architecture for integration.
- No integrated battery backup or UPS functionality.
Setup, Compatibility & Care
Setup:
- Ensure the main power disconnect is OFF before installation.
- Mount the unit securely within the control panel, adhering to ventilation guidelines.
- Connect the 100-240 VAC input power to the designated terminals.
- Connect the 5 VDC output terminals to the CJ series PLC backplane or expansion modules.
- Wire the dedicated RUN output signal to an appropriate monitoring circuit or indicator.
- Verify all connections before restoring main power.
Compatibility:
- Primarily designed for Omron CJ series PLC systems, including the CJ1M series.
- Verify the total power consumption of your CPU and expansion modules does not exceed the 5A output capacity.
Care:
- Keep ventilation slots clear of dust and debris. Use compressed air for cleaning.
- Periodically check wiring for signs of wear or loose connections.
- Avoid exposing the unit to excessive moisture or corrosive environments.
