Specification

The Omron CJ-series output units, specifically the CJ1W-OD231, CJ1W-OD233, and CJ1W-OD234, are engineered to deliver precise and reliable digital output control in demanding industrial environments. These modules are part of the CJ1 family, offering high-density NPN open-collector outputs with fast switching capabilities, making them ideal for driving actuators, solenoids, and indicator arrays. The CJ1W-OD231 and CJ1W-OD233 provide 32 output points, while the CJ1W-OD234 expands to 64 points, each with individual photocoupler isolation for enhanced noise immunity. With a rated output voltage of 24 VDC and a maximum load current of 0.3 A per point, these units ensure robust performance in assembly lines, packaging machinery, and process control systems. Their compact design and compatibility with Omron’s CX-Programmer software simplify configuration and maintenance, reducing downtime in critical operations.

Output Configuration: Each point provides NPN sinking output with a maximum of 0.3 A at 24 VDC, suitable for direct drive of low-power loads like relays and LEDs.
High-Speed Switching: Supports up to 10 kHz switching frequency for precise control in high-speed applications such as sorting and indexing.
Isolation and Protection: Photocoupler isolation per output ensures electrical separation between the PLC and field devices, with built-in overcurrent and surge protection for enhanced durability.
Diagnostic Capabilities: Green LED indicators on each channel allow immediate visual verification of output status, simplifying system debugging and maintenance.
Power and Connectivity: Operates on 5 VDC internal bus power with low current draw (0.1–0.15 A), and uses a 40-pin removable terminal block for secure wiring in control panels.
Environmental Resilience: Rated for 0°C to 55°C operating temperature and 10% to 90% non-condensing humidity, ensuring reliable performance in typical industrial settings.
