The GE IC697CGR935 is a high-performance single-slot CPU module designed for Hot Standby redundancy systems in GE Fanuc Series 90-70 PLC architectures. It is engineered for applications that require continuous operation, zero-downtime switching, and deterministic control performance.
Unlike standard CPU modules, the CGR935 is specifically built for redundant dual-CPU configurations, enabling automatic synchronization between primary and backup controllers. This makes it a trusted solution in critical industries such as power generation, oil & gas, and large-scale process automation.
