Original GE Fanuc IC697CHS790 PLC Mainframe Chassis

Product Overview

The GE Fanuc IC697CHS790 functions as the structural and electronic backbone for the Series 90-70 PLC system. This 100% Brand New original 9-slot baseplate provides the physical housing and high-speed VME-based backplane required for complex industrial automation. It accommodates one power supply, one CPU, and up to seven specialized I/O or communication modules. By providing a ruggedized interconnect for data and power distribution, the IC697CHS790 enables high-performance processing in large-scale control applications.

Technical Specifications

Engineering Advantages

• High-Speed VME Backplane: The IC697CHS790 utilizes a VME-based backplane architecture. This allows for massive data throughput between the CPU and high-density I/O modules, ensuring the controller handles complex algorithms and high-speed motion tasks without communication bottlenecks.

• Rugged Mechanical Alignment: Precision-engineered card guides ensure perfect alignment between module connectors and the backplane pins. This design prevents pin damage during installation and maintains a vibration-resistant connection in high-impact industrial environments.

• Unified Power Distribution: The integrated backplane traces distribute regulated power from the power supply module to all nine slots. This centralized distribution eliminates point-to-point internal wiring, reducing potential failure points and simplifying cabinet thermal management.

• Scalable Control Architecture: With seven dedicated I/O slots, this chassis supports a diverse mix of digital, analog, and specialized coprocessors. It provides sufficient headroom for system expansion as plant requirements grow, avoiding the need for immediate rack upgrades.

• Superior Grounding and Shielding: The heavy-gauge metal chassis provides a common ground reference for all installed modules. This construction effectively drains EMI/RFI noise to the panel ground, protecting sensitive CPU logic from the electrical interference found in heavy industrial settings.

FAQs

• Does the IC697CHS790 include the power supply module?

  No. The IC697CHS790 is the empty baseplate/chassis. You must purchase the Series 90-70 power supply (such as the IC697PWR series) and CPU separately based on your specific application requirements.

• Can I use Series 90-30 modules in this 9-slot rack?

  No. The IC697CHS790 is designed exclusively for the Series 90-70 form factor and backplane. Series 90-30 modules utilize a different physical size and bus protocol and are not compatible with this chassis.

• What mounting precautions should I take for this chassis?

  Install the chassis vertically on a flat, grounded metal surface within an enclosure. Ensure at least 2 inches of clearance above and below the rack to allow for natural convection cooling of the high-power Series 90-70 modules.
