Description

The GE Fanuc IC697CHS790 is a specialized 9-slot chassis designed for the Series 90-70 PLC platform. This rear-mounted rack provides the essential physical and electrical infrastructure for IC697 automation modules. It facilitates high-speed communication across the backplane while distributing stable power to all installed components. Now supported by Emerson Automation, this chassis remains a foundational element for large-scale industrial control systems. It provides a robust environment for CPUs, I/O modules, and specialized communication adapters.

Design and Configuration

This 19-inch wide rack allows for efficient organization within standard industrial control cabinets. The backplane utilizes four jumpers to define unique rack identification and addressing. Consequently, the CPU can accurately locate and manage modules across expanded system architectures. The mechanical design also features interlocking tabs to ensure secure module seating. Furthermore, integrated grounding and shielding protect sensitive electronics from electromagnetic interference. This construction ensures long-term stability in electrically noisy plant environments.

Expansion and Thermal Management

Users can link two IC697CHS790 racks to share a single power supply unit. This configuration requires the IC697CBL700 extension cable kit for proper voltage distribution. For high-heat applications, the chassis supports optional fan assemblies to maintain safe operating temperatures. Specifically, it accommodates the IC697ACC721 (120VAC) or IC697ACC724 (240VAC) cooling units. These additions prevent thermal throttling and extend the lifespan of the internal PLC components.

Installation and Reliability

The chassis fits easily into shallow enclosures requiring only 10 inches of depth clearance. Its VME compliance ensures high-speed data throughput for complex automation logic. Technicians can quickly swap modules while the interlocking mechanism maintains alignment. Additionally, the rugged steel frame resists vibration and physical stress in heavy industrial sectors. This chassis represents a dependable solution for power generation, water treatment, and manufacturing facilities.
