IC695RMX128-EG - 128MB Multi Mode Fiber Redundancy Memory Xchange Module for GE Fanuc PACSystems RX3i

The IC695RMX128-EG is a GE Fanuc / Emerson PACSystems RX3i Redundancy Memory Xchange module designed for high-speed reflective memory communication and RX3i Hot Standby CPU redundancy applications. This module provides 128 MB of reflective memory and uses multi mode fiber connectivity for fast data transfer between compatible RX3i controllers or reflective memory network nodes.

This module is commonly used in RX3i redundant control systems where a dedicated fiber-optic communication link is required between the primary and secondary controller systems. It may also be used as a reflective memory node in supported high-speed memory exchange network applications when properly configured.

Revision / Suffix Notice

This listing is specifically for revision IC695RMX128-EG.

Other revision suffixes such as IC695RMX128-AA, IC695RMX128-AB, IC695RMX128-AC, IC695RMX128-AD, IC695RMX128-AE, IC695RMX128-BE, and other later revisions may exist, but they are not listed here as automatic substitutes.

Revision suffixes may reflect hardware revision, firmware revision, manufacturing changes, agency certification labeling, branding updates, or customer-specific validation requirements. In industrial automation and redundancy systems, the exact revision may be important.

⚙️ Fit Notes

• This listing is for IC695RMX128-EG only.
• Match the revision suffix before ordering if your system requires an exact replacement.
• Do not substitute IC695RMX128-EG for another suffix unless the customer or site engineer approves the revision change.
• Confirm your system requires the multi mode fiber version. IC695RMX228 is the single-mode fiber version and is not the same module.
• This module requires a compatible RX3i Universal Backplane / PCI backplane environment.
• For Hot Standby redundancy systems, matching RMX modules may be required on both the primary and secondary controller sides.
• When used as a redundancy communication link, the RMX module should not also be used as a general-purpose Memory Xchange network node.
• Verify CPU compatibility, firmware requirements, fiber cable type, node configuration, and Proficy Machine Edition project settings before installation.
• Industrial control systems may require exact revision matching due to plant standards, validated configurations, safety documentation, or maintenance procedures.
