Product Overview

The IC695RMX128-AC is a high-speed Redundancy Memory Xchange (RMX) module for GE Fanuc RX3i PACSystems, designed to support high-availability and fault-tolerant automation architectures. It provides ultra-fast synchronization between primary and secondary CPUs using a dedicated fiber-optic reflective memory link. This ensures both controllers remain continuously synchronized in a hot-standby configuration, enabling seamless takeover in the event of a failure. Supplied as 100% Brand New original equipment, it is intended for mission-critical industrial systems requiring zero-downtime operation.

Technical Specifications

Engineering Advantages

Deterministic Data Synchronization
Reflective memory architecture mirrors data between redundant CPUs in real time, independent of CPU scan cycles, ensuring zero-latency state synchronization.

Complete Electrical Isolation
Fiber-optic communication eliminates ground loops and protects the system from electromagnetic interference in high-noise industrial environments.

Extended Communication Distance
Supports fiber links up to 300 meters using multi-mode fiber, allowing redundant racks to be placed in separate control rooms or isolated safety zones.

Bumpless Transfer Capability
Enables near-instant failover between primary and secondary CPUs within one scan cycle, maintaining continuous process control without interruption.

FAQs

Does this module require a specific CPU?
Yes. It is only compatible with RX3i redundancy-capable CPUs such as IC695CRE311 and IC695CRE315.

What type of fiber cable is required?
Multi-mode fiber optic cables with LC connectors are standard. Single-mode solutions may be used for extended distances beyond 300 meters with appropriate configuration.

How many modules are required for redundancy?
A full redundant system requires two IC695RMX128-AC modules—one in each chassis—connected via fiber optic links.

Is this a brand new product?
Yes. The IC695RMX128-AC is supplied as 100% Brand New original equipment in factory-sealed packaging.
