IC695RMX128-AB - 128MB Redundancy Memory Xchange Module for GE Fanuc PACSystems RX3i

The IC695RMX128-AB is a GE Fanuc PACSystems RX3i Redundancy Memory Xchange module designed for high-speed reflective memory communication and RX3i Hot Standby redundancy applications. This module provides 128 MB of reflective memory and is used to exchange data between compatible RX3i controllers or reflective memory network nodes over a high-speed fiber-optic communication path.

This module is commonly installed in RX3i redundancy systems where a dedicated RMX communication link is required between the primary and secondary controller racks. It may also be used in supported reflective memory network applications when configured for general-purpose memory exchange operation.

Revision / Suffix Notice

This listing is specifically for revision IC695RMX128-AB.

Other IC695RMX128 revision suffixes 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.

If your application requires IC695RMX128-AB specifically, please verify the revision suffix before ordering.

⚙️ Fit Notes

• This listing is for IC695RMX128-AB only.
• Match the revision suffix before ordering if your system requires an exact replacement.
• Do not substitute IC695RMX128-AB 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.
• RMX redundancy links are typically installed as a two-node fiber ring between the primary and secondary RX3i controller racks.
• 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.
