Product Description

Description

Engineered for medium-to-large scale industrial automation, the CJ1G-CPU44H functions as a high-performance central processing unit within the Sysmac CJ1G product family. This module features a backplane-free structural design that optimizes control panel space while providing high-speed instruction execution. It is designed to handle complex data management tasks, coordinate digital and analog I/O points, and execute high-density ladder logic configurations with minimal cycle times.

The unit supports direct connection of expansion racks and specialized communication modules, allowing seamless integration across distributed industrial networks. Utilizing internal flash memory and support for memory cards, the processor ensures reliable retention of application software and operational logs during power disruptions. Its architecture is suited for manufacturing systems requiring fast cycle times and flexible network configuration options.

Features

  • High-speed logic processing with an execution time of 0.04 microseconds for basic instructions.
  • Bus-less connection system allowing direct side-by-side module expansion without a traditional backplane.
  • Built-in peripheral and RS-232C serial communication ports for programming and HMI connectivity.
  • Support for optional memory cards to facilitate data logging and program transfer.
  • Comprehensive diagnostic utilities monitor CPU health, battery status, and memory integrity.

Applications

  • Material handling and conveyor routing systems.
  • Multi-axis packaging and assembly machines.
  • Water and wastewater municipal treatment stations.
  • Environmental chamber control and HVAC integration.
