GE IC695RMX128 Redundancy Module: Key Specs & Review
The GE IC695RMX128 redundancy memory exchange module plays a vital role in PACSystems RX3i redundant CPU systems. Emerson Automation manufactures this module, formerly GE Intelligent Platforms. It provides 128 MB SDRAM user memory and supports high-speed 2.12 Gbaud fiber-optic networking. This review highlights the technical specifications, features, and applications strictly from the product data.
Core Technical Specifications
The IC695RMX128 functions as a dedicated link between redundant RX3i CPUs or as a node in a reflective memory network. It occupies a single slot in the RX3i rack and supports hot insertion and removal. The module draws 580 mA at 3.3 VDC and 220 mA at 5 VDC. Engineers connect it via single-mode fiber-optic LC type connectors. The network transmits data at 2.12 Gbaud and supports up to 256 nodes. Network error detection ensures reliable operation.
Memory and Configuration Details
The module includes 128 MB SDRAM for reflective memory operations. Configuration relies entirely on programming software, so technicians avoid cumbersome jumper or DIP switch settings. This software-based approach simplifies modifications and reduces hardware interruptions. The IC695RMX128 works specifically with the RMC128/RMX228 module and supports redundancy applications only. It does not serve general-purpose memory Xchange. A complete communication path requires two RMX units – primary and secondary – linked by two fiber-optic cables forming a 2-node ring.
Network Performance and Connectivity
The reflective memory network updates all nodes instantly when any node changes. Data transmission follows a daisy-chain loop from node to node until the final receiver obtains the data. The fiber-optic connector uses a zirconium ceramic ferrule with a maximum insertion loss of 0.35 dB. With up to 256 nodes per network, the IC695RMX128 provides excellent scalability for large redundancy architectures.
Practical Applications
Engineers apply the IC695RMX128 primarily in hot standby CPU redundancy systems. A backup CPU maintains constant data synchronization with the main CPU, ensuring seamless failover if the primary fails. This module suits process control, manufacturing, and critical infrastructure where uptime is essential. System integrators benefit from the easy software configuration and hot-swap capability.
Conclusion
The GE IC695RMX128 offers reliable, high-speed memory exchange for PACSystems RX3i redundant CPU systems. Its 128 MB memory, 2.12 Gbaud fiber-optic network, and support for up to 256 nodes meet demanding industrial requirements.
