Description

For high-performance machine automation, the CJ2H-CPU66 provides advanced processing power and expanded memory capacity within the Omron CJ2 Series PLC platform. Designed to handle complex motion control and high-speed data processing, this central processing unit (CPU) features 150K steps of program memory and supports up to 2560 local I/O bits. System designers benefit from fast execution times, minimizing cycle overhead and maximizing throughput in demanding industrial automation applications.

This CPU module integrates versatile program allocation options, extensive function block capabilities, and onboard serial communication. The unit is optimized for mounting inside a control panel, maintaining low current consumption from the backplane and utilizing standard grounding protocols to ensure robust noise immunity.

Features

  • Fast instruction execution with basic instructions processed at 0.016 us minimum and special instructions at 0.048 us minimum.
  • Generous user program memory capacity of 150K steps to handle complex control logic.
  • Supports up to 2560 direct-addressable I/O bits.
  • Function block support for up to 2048 definitions and 2048 instances to enable modular, reusable programming.
  • Integrated memory card slot compatible with 128 MB, 256 MB, and 512 MB compact flash media.
  • Built-in serial port supporting half-duplex start-stop synchronization with baud rates up to 115.2 kbps.

Applications

  • High-speed packaging and sorting machinery
  • Automated assembly systems and material handling
  • Semiconductor fabrication equipment
  • Water and wastewater municipal treatment stations
  • Multi-axis motion synchronization systems
