Description
Product Introduction & Engineering Value
When a production line expands over time, controller performance often becomes the limiting factor rather than the I/O hardware. The GE IC695CPU315 provides a significant increase in processing capability for PACSystems RX3i applications while maintaining compatibility with many existing Series 90-30 I/O modules.
Built around a 1 GHz processor, the CPU combines high-speed logic execution, generous user memory, flexible communication options, and field-upgradable firmware. It is widely deployed in continuous-process industries where deterministic control and long-term platform support are essential.

Field Application & The “Trench” Experience
A food processing facility upgraded its packaging line to include additional vision inspection stations and PROFINET-connected equipment. The existing controller began approaching its scan-time limits during peak production.
Replacing the older processor with an IC695CPU315 reduced scan times, increased communication capacity, and allowed the engineering team to add new diagnostics without redesigning the control strategy. The migration required only minor application updates because the existing RX3i infrastructure remained in place.
Typical applications include:
- High-speed packaging and palletizing systems
- Automotive body shop conveyor coordination
- Chemical batch process automation
- Water and wastewater supervisory control
- Large material handling systems with distributed I/O

The Veteran’s Tech Trap Guide
⚠️ Check Firmware Before Swapping CPUs
Installing a newer IC695CPU315 into an older RX3i system without updating firmware or Proficy Machine Edition may result in configuration mismatches or unsupported hardware messages.
⚠️ Verify Battery Condition
The processor uses battery-backed SRAM for memory retention. A weak or expired battery may not affect normal operation immediately, but it can lead to memory loss during extended power outages.
PRO TIP:
If you’re migrating from an earlier RX3i CPU, review Ethernet modules, PROFINET devices, and communication firmware before commissioning. Many startup issues originate from version incompatibilities rather than CPU hardware.
⚠️ Confirm Backplane Compatibility
The IC695CPU315 is designed for the RX3i Universal Backplane. Although it supports many legacy Series 90-30 I/O modules, compatibility should always be verified before expanding an existing system.
Dynamic FAQ
Q1. What processor is used in the ?
The module uses a 1 GHz Intel Celeron M processor, providing substantially higher processing capability than earlier RX3i CPU generations.
Q2. How much application memory is available?
The CPU provides 20 MB of battery-backed user memory and 20 MB of Flash memory for application storage and firmware support.
Q3. Which communication interfaces are built into the CPU?
The includes one RS-232 serial port and one RS-485 serial port supporting SNP, Modbus, and Serial I/O communication. Additional Ethernet capability is available through compatible RX3i communication modules.
Q4. Is New Surplus inventory genuine?
Yes. New Surplus units are genuine unused OEM inventory that has remained in controlled warehouse storage. Each module is visually inspected and verified before shipment.
Q5. What testing is performed on refurbished CPUs?
Refurbished units undergo power-up testing, CPU diagnostics, memory verification, communication port testing, firmware inspection, and extended burn-in before release.
Q6. Can the be used with existing Series 90-30 I/O?
Yes. The CPU supports many Series 90-30 I/O modules through the RX3i Universal Backplane, making it suitable for phased modernization projects. Compatibility should always be confirmed against the current hardware configuration and firmware revision before installation.
