Description

Designed for mid-to-high range industrial automation tasks requiring efficient data processing and compact form factors, the CJ1G-CPU43H serves as a high-performance central processing unit within the Omron SYSMAC CJ1 platform. This processor architecture eliminates the need for a traditional physical backplane, utilizing a modular, block-style connecting system that saves critical control cabinet space.

The CJ1G-CPU43H is engineered to manage up to 960 local digital and analog I/O points, making it highly suitable for manufacturing, assembly, and packaging systems. Its memory layout provides a dedicated program capacity of 20 Ksteps alongside a comprehensive data memory capacity of 64 Kwords. Dual integrated communication ports facilitate direct engineering access and peer-to-peer data transfers, ensuring seamless integration with human-machine interfaces (HMIs) and supervisory control networks.

Features

  • Backplane-free configuration allowing direct DIN-rail modular expansion.
  • High-speed logic instruction execution optimized for complex sequencing.
  • Built-in peripheral port and RS-232C interface for configuration, monitoring, and serial communication.
  • Support for CJ-series high-speed Special I/O and CPU Bus Units.
  • Flash memory backup for user programs and parameter data without battery reliance.

Applications

  • Automated packaging and cartoning machinery.
  • Multi-axis material handling and conveyor systems.
  • Water and wastewater municipal treatment stations.
  • HVAC and building environmental control networks.

Installation Guidelines

  • Ensure all power to the system rack is disconnected before attaching or removing the CPU module.
  • Mount the module securely onto a standard 35mm DIN rail, locking the yellow slider indicators on adjacent units to guarantee solid bus connectivity.
  • Maintain a minimum of 20mm clearance above and below the unit to ensure adequate ventilation and prevent overheating.
  • Keep communication and high-voltage signal cables in separate conduits to minimize electromagnetic interference (EMI).

Compliance and Certifications

  • CE Directive Compliance
  • UL and cUL Listed
