Product Title

GE IC695RMX128 – RX3i Redundancy Memory Xchange Module

Product Overview

The GE IC695RMX128 is a high-performance redundancy memory exchange module designed for the PACSystems RX3i platform. It enables high-speed, deterministic data sharing between redundant CPUs or across a reflective memory network, ensuring continuous system operation in mission-critical applications.

By utilizing reflective memory technology, the IC695RMX128 automatically synchronizes data across multiple nodes in real time. This makes it an essential component in high-availability control systems where zero data loss and seamless failover are required. The module is commonly deployed in hot standby CPU configurations, ensuring that backup controllers maintain identical memory states for immediate takeover in case of primary system failure.
