GE IC697CHS791RR 9-Slot Redundant PLC Rack
Engineered for High-Availability Industrial Control Systems
Engineered for High-Availability Industrial Control Systems
Product Overview
The GE IC697CHS791RR is a 9-slot front-mount PLC rack designed for mission-critical industrial automation systems requiring continuous operation. As part of GE Fanuc’s Series 90-70 platform, this rack integrates dual redundant power supply slots and advanced backplane architecture to eliminate single points of failure. It supports seamless integration with GE’s modular I/O modules, CPUs, and communication processors, making it ideal for applications where downtime is costly, such as power generation, oil refining, and pharmaceutical manufacturing.
Featuring a 19-inch standard rack-mount form factor (483 mm width), the IC697CHS791RR ensures compatibility with industry-standard enclosures. Its front-mount design simplifies module installation and maintenance, while mechanical keying prevents incorrect module insertion. The rack’s dual backplane buses (VMEbus C.1 compliant) enable simultaneous data transfer at speeds exceeding 40 MB/s, ensuring real-time synchronization between redundant components. This architecture supports hot-swappable operation, allowing online replacement of modules without system disruption.
With a wide operating temperature range (-20°C to +60°C) and resistance to EMI/RFI interference, the IC697CHS791RR excels in harsh industrial environments. Its redundant power supply capability (24 VDC ±10%) ensures uninterrupted operation even during power fluctuations, while built-in diagnostic LEDs provide real-time status monitoring.

Key Features and Advantages
Dual Redundant Power Supply Slots: The IC697CHS791RR supports two independent 24 VDC power supplies (e.g., GE IC697PWR721), ensuring continuous operation during power failures. Automatic failover between supplies minimizes downtime.
Dual Backplane Buses: The redundant VMEbus C.1 backplanes provide parallel data paths, enhancing system resilience and enabling fault-tolerant configurations. This design is critical for applications requiring high-speed data synchronization, such as hot standby CPU systems (e.g., GE IC697CGR935).
Hot-Swap Capability: Field-replaceable modules allow online maintenance, reducing mean time to repair (MTTR) by up to 50%. LED indicators on each slot provide instant status feedback for troubleshooting.
Rugged Construction: Built with heavy-gauge steel and IP20-rated enclosure, the rack withstands shock (15 g, 11 ms) and vibration common in industrial settings. Its wide temperature range ensures reliability in extreme environments.
Scalable Configuration: Users can configure the rack with up to 9 modules, including redundant CPUs, I/O cards, and communication modules. This flexibility supports phased system expansions while maintaining compatibility with legacy GE Fanuc systems.
Application Areas
The GE IC697CHS791RR is widely adopted in industries demanding high availability and fault tolerance:
- Power Generation: Supporting redundant CPUs (e.g., GE IC697CPU780) for turbine control and grid synchronization, ensuring stable energy output.
- Oil & Gas: Managing critical processes in offshore platforms, such as wellhead monitoring and emergency shutdown systems, where downtime risks environmental hazards.
- Pharmaceuticals: Maintaining sterile manufacturing environments by controlling HVAC systems and cleanroom conditions with redundant I/O modules (e.g., GE IC697MDL750).
- Water Treatment: Ensuring continuous operation of wastewater treatment plants through redundant communication modules (e.g., GE IC697CMM711) for SCADA integration.
Its compatibility with GE’s Genius I/O and GMR (Genius Modular Redundancy) systems makes the IC697CHS791RR ideal for retrofitting aging automation infrastructure without replacing existing software or field devices.
