The GE IC695CRU320 is a high-reliability redundancy CPU module designed for the PACSystems RX3i automation platform, built to support hot standby (HSB) redundant control architectures.
It is specifically engineered for mission-critical industrial systems where continuous operation is required without downtime, even in the event of CPU failure. The CRU320 works as part of a dual-controller redundancy pair, ensuring seamless switchover between primary and backup CPUs.
This module is widely deployed in process industries, power generation, chemical plants, and large-scale manufacturing systems, where system interruption is not acceptable.
