Omron CJ1H-CPU65H CJ1 Series PLC CPU Unit

Description

Designed for high-speed, large-scale industrial automation applications, the Omron CJ1H-CPU65H serves as a high-performance central processing unit within the highly modular CJ1 PLC series. This CPU module is optimized for complex processing tasks that demand rapid execution times, extensive memory allocation, and seamless synchronization across multiple system components. By providing substantial program capacity and expansive I/O handling, it functions as the core controller in demanding system architectures without requiring a traditional backplane, saving critical control cabinet space.

The CJ1H-CPU65H programmable controller supports advanced instruction execution speeds, ensuring minimal cycle times for precision positioning and sequence control. With its high-capacity memory banks and flexible rack expansion options, industrial operators can scale their automation architecture to manage hundreds of field devices and extensive data logging tasks.

Technical Specifications

Connections and Interfaces

Installation Guidelines

• Ensure the system power supply is completely disconnected before mounting or removing the CPU unit.
• Mount the CPU unit securely onto a standard 35mm DIN rail, ensuring the yellow DIN rail mounting hooks are fully locked into place.
• Provide a minimum clearance of 20mm above and below the unit to allow natural convective airflow and prevent heat buildup.
• Ground the PLC system using a dedicated ground wire of 2 square millimeters or thicker, maintaining a ground resistance of less than 100 ohms.
• Verify that the total current consumption of all connected modules does not exceed the maximum output capacity of the system power supply module.

Compliance and Certifications

• CE Directive Compliance
• UL Listed (cULus Industrial Control Equipment)
• NK / Lloyd's Register marine standards (where applicable)
