Omron CJ1H-CPU67H SYSMAC CJ1 Series CPU Unit

Description

Designed for high-speed, large-scale industrial automation architectures, the Omron CJ1H-CPU67H functions as a high-performance central processing unit within the SYSMAC CJ1 series PLC platform. This CPU unit provides expansive program capacity and memory structures to manage complex control algorithms and high-density I/O configurations without compromising processing cycle times. It facilitates rapid execution speeds and accommodates up to 40 mountable units across a maximum of 3 expansion racks, making it ideal for high-throughput machinery and distributed control layouts.

The unit features a slotless, compact form factor that optimizes DIN-rail space. Equipped with a dedicated peripheral port and a standard RS-232C serial interface, it allows for direct connection to HMIs, programming devices, and serial networking nodes. It supports dynamic memory allocation to store extensive recipe, logging, and operational variables required for complex production processes.

Features

• High-speed instruction execution processing basic instructions (LD) in 0.02 microseconds.
• Expansive memory allocation to handle extensive programming requirements.
• System expandability with support for up to 40 local and expansion I/O modules.
• Built-in RS-232C and peripheral communication ports for simple system integration.
• Slotless configuration allowing direct connection to neighboring power and I/O modules.

Applications

• Automated packaging and material handling systems
• Multi-axis synchronized motion and positioning systems
• Automated assembly lines and high-speed sorting systems
• Industrial manufacturing machinery requiring large data memory arrays

Installation Guidelines

• Mount the CPU unit directly to the left-most slot of the CJ-series backplane, adjacent to the power supply module.
• Ensure that the cumulative current consumption of the CPU and all mounted modules does not exceed the power supply module's rated output capacity.
• Maintain clear ventilation spacing above and below the rack as specified in the SYSMAC user manual.
• Use shielded, high-quality RS-232C cabling to mitigate potential electromagnetic interference (EMI) in electrically noisy environments.

Compliance and Certifications
