Description
GE Emerson IC695RMX128‑BE PACSystems RX3i Redundancy Memory Xchange Module
Product Details
The IC695RMX128‑BE is a redundancy memory xchange module for PACSystems RX3i platform, manufactured by Emerson (Former GE Fanuc Intelligent Platforms). It is equipped with 128 MB shared SDRAM, adopting LC‑type single‑mode fiber‑optic interface with 2.12 Gbaud transmission speed for deterministic reflective‑memory data synchronization. This module serves as dedicated high‑speed link between primary and standby CPUs in hot‑standby redundancy system, and also works as network node for reflective‑memory network with maximum 256 supported nodes per loop. It occupies one single slot on RX3i universal backplane, supports hot‑swap operation. Multiple front‑panel LED indicators display local/remote status, link health and fault information. It undertakes real‑time mirroring of CPU memory data, realizes bumpless switch‑over during main CPU failure, widely used as original spare‑part for high‑availability industrial control racks.
Applications
‑ Oil & gas critical process control with hot‑standby PLC redundancy ‑ Petrochemical DCS & safety‑related control systems ‑ Power plant and auxiliary equipment high‑reliability automation ‑ Water‑wastewater treatment large‑scale distributed control ‑ Manufacturing production line non‑stop mission‑critical control ‑ Reflective‑memory multi‑node distributed data sharing network ‑ Retrofit and spare‑part replacement for PACSystems RX3i redundant racks
