GE IC695RMX128 – PACSystems RX3i Redundant Memory Xchange Module

In stock

Product Introduction:

The IC695RMX128 is a high‑speed redundant memory exchange module for the Emerson PACSystems RX3i PLC platform, designed to enable real‑time data synchronization between redundant RX3i CPUs in hot‑standby configurations. It acts as a dedicated fiber‑optic link, mirroring 128MB of shared memory between the primary and standby CPUs at ultra‑high speeds, ensuring seamless failover (≤5ms) with zero data loss. Engineered for high‑availability industrial control systems, it eliminates the need for slow Ethernet‑based synchronization, delivering deterministic, lossless data replication for critical applications requiring uninterrupted operation.
