The GE IC695CMU310 is a high-performance CPU redundancy module specifically designed for GE’s PACSystems RX3i platform. It provides hot-standby redundancy, meaning that if the primary CPU fails, the backup CPU automatically and seamlessly takes over control with no loss in system operation. This module plays a critical role in mission-critical automation systems where system downtime is unacceptable.

The IC695CMU310 ensures high availability in industrial automation environments by supporting full redundancy, real-time synchronization between CPUs, and deterministic control. Built with robust and industrial-grade components, this CPU module is an ideal choice for users who require uninterrupted processing capabilities in sectors like power generation, oil & gas, water treatment, transport, and manufacturing automation.

With a modular design, the IC695CMU310 integrates easily with the RX3i system and supports scalable configurations for both small and large applications. It delivers exceptional speed, memory, and communication capabilities in a compact footprint.
