Product Overview

The GE Fanuc IC697CGR935 is a high-performance, single-slot CPU designed specifically for the Series 90-70 PLC platform. This module is engineered to support Hot-Standby redundancy, making it a critical component for industrial processes that require 24/7 availability and zero-fail safety. When deployed in a redundant pair, the IC697CGR935 synchronizes data across a dedicated high-speed link, allowing a secondary processor to assume control of all I/O and logic execution instantly if the primary unit encounters a fault. This seamless bumpless transfer ensures that large-scale industrial operations continue without interruption or loss of process state.
