GE Fanuc, now part of Emerson Automation, built a reputation over decades for rugged, dependable PLC hardware that keeps critical processes running without interruption. Their PACSystems RX3i line in particular became a standard choice for facilities that needed high availability control, especially in industries where an unplanned shutdown carries a real cost.
One part that regularly comes up in high availability control system maintenance is the GE Fanuc IC695CMU310, a Max-ON hot standby redundancy CPU from the RX3i family. For facilities across the UAE, Saudi Arabia, and Pakistan running redundant control architectures, sourcing a genuine, tested replacement quickly matters, since these modules are typically protecting processes that cannot afford downtime. ILM Surplus Fze supplies both new and surplus GE Fanuc components to keep these systems running.
Why GE Fanuc Stands Out in Automation
GE Fanuc built the RX3i platform to handle demanding, continuous duty control applications, and the Max-ON CPU line takes that a step further by adding hot standby redundancy directly into the processor itself. Instead of relying on external failover hardware, the IC695CMU310 switches from master to backup in three scans or less, with no loss of I/O state, which is a meaningful advantage for processes where even a brief interruption is unacceptable.
GE Fanuc products are widely used in:
Power generation for turbine and boiler control systems. Oil and gas facilities for high availability process control. Water and wastewater treatment for continuous pump and valve automation. Manufacturing plants requiring redundant control architecture for critical lines.
Their product portfolio spans several key areas.
CPU Modules. Standard and redundant processors like the IC695CMU310 for the RX3i platform. I/O Modules. Discrete and analog input and output modules for RX3i and Series 90-30 backplanes. Communication Modules. Ethernet, serial, and fieldbus interfaces for integrating RX3i systems into larger networks. HMI and Software. Programming and visualization tools built around the PACSystems ecosystem.

Popular GE Fanuc Automation Parts and Models
Here is a list of high demand GE Fanuc part numbers commonly sourced for RX3i system maintenance across the region.
IC695CMU310. RX3i Max-ON hot standby redundancy CPU, 300 MHz, 10 MB memory, dual Ethernet. IC695CPU310. Standard RX3i CPU, 300 MHz, 10 MB RAM, two serial ports. IC695CPE305. RX3i CPU module for standard, non redundant control applications. IC693CPU374. Series 90-30 CPU module, still widely used in legacy installations. IC695CHS016. RX3i 16 slot universal backplane.

These parts are in steady demand for both new redundant control installations and emergency CPU replacements in Dubai, Saudi Arabia, and Pakistan.
Applications of GE Fanuc IC695CMU310 RX3i Max-ON CPU Module Products
1. Power Generation
The IC695CMU310’s Max-ON redundancy keeps turbine, boiler, and standby power control systems running through a CPU failure, since the backup module takes over within three scans without dropping I/O state.
2. Oil and Gas Processing
High availability control is critical in remote and hazardous processing environments, where redundant CPUs like the IC695CMU310 reduce the risk of costly unplanned shutdowns.
3. Water and Wastewater Treatment
Continuous pump and valve automation depends on control systems that can tolerate a hardware failure without interrupting the process, which is exactly the role Max-ON redundancy plays.
4. Manufacturing Lines
High value or continuous manufacturing processes use redundant RX3i architecture to protect against downtime on lines where a stoppage is expensive to recover from.
5. Legacy System Support
Many facilities still run Series 90-30 and early RX3i hardware alongside newer modules, and GE Fanuc’s universal backplane support makes mixed generation systems easier to maintain.

Advantages of Choosing Genuine or Properly Tested GE Fanuc Parts
Long Term Reliability. Built to handle continuous operation in critical control environments. Hot Standby Redundancy. Max-ON CPUs like the IC695CMU310 minimize downtime risk with fast, seamless failover. Backward Compatibility. Universal backplane support allows RX3i and Series 90-30 hardware to coexist. Expanded Memory. 10 MB of battery backed RAM and 10 MB of flash memory support large, complex programs. Reduced Downtime. Durable construction and proven failover performance support long, stable service life.
