Description
Description
The IC697CHS790 is a high-performance 10-slot backplane module developed by GE Fanuc (now part of Emerson’s industrial automation portfolio) for the RX3i Programmable Logic Controller (PLC) system. As the central “nerve center” of the RX3i rack, it provides the physical and electrical connection between the CPU, I/O modules, and communication modules, enabling high-speed data transfer and reliable operation in demanding industrial environments. Its rugged design, high-density slot configuration, and advanced backplane technology make it an essential component for building scalable, high-performance automation systems.
Application Scenarios
A large automotive parts manufacturer in Ohio faced a significant challenge when expanding its production line: the existing control system was spread across multiple small cabinets with limited I/O capacity, resulting in complex wiring, increased maintenance costs, and slower system response times. By implementing the IC697CHS790 as the central backplane in a new RX3i system, the manufacturer was able to consolidate its control architecture into a single, high-density rack. This reduced wiring complexity by 60%, improved system response time by 40%, and simplified maintenance procedures. The IC697CHS790’s robust design also proved reliable in the plant’s harsh environment, operating continuously without failure for over two years.
