GE CPU310 RX3i CPU Module

The GE CPU310 RX3i (part number IC695CPU310) is the central processing unit for the PACSystems RX3i industrial PAC platform, built for real-time sequence and process control. This GE CPU310 RX3i executes control logic, manages backplane I/O scanning and network data exchange for the RX3i rack system. The GE CPU310 RX3i is widely stocked as an original spare for maintenance and retrofit of legacy GE PACSystems control cabinets.

The GE CPU310 RX3i comes with 10 MB user memory plus non-volatile flash storage, supporting battery-backed memory retention. It works with PAC Machine Edition engineering software for program download, online editing and fault diagnostics. It supports multiple programming languages including ladder diagram, structured text, function block diagram and C language. The GE CPU310 RX3i features dual backplane architecture: high-speed PCI bus for newer RX3i I/O and serial bus for migration of older Series 90-30 I/O modules. Status indicators on the GE CPU310 RX3i show run, fault and communication states for quick on-site troubleshooting.

This GE CPU310 RX3i installs into the RX3i universal rack and works with the full range of RX3i I/O, communication cards and power supplies. It has serial ports for SNP slave communication with HMI and programming devices, and Ethernet networking can be expanded by adding separate Ethernet modules. The GE CPU310 RX3i supports firmware upgrade in the field, and it meets industrial EMC standards to withstand vibration and electrical noise in factory control rooms. Its control firmware and backplane protocol follow GE original specifications, so existing application logic can remain unchanged after replacement.

The GE CPU310 RX3i is commonly deployed in water treatment, power auxiliary control, material handling and general process production lines based on PACSystems RX3i. Replacing a failed controller with the GE CPU310 RX3i restores the whole PAC control system rapidly. As a classic RX3i CPU, the GE CPU310 RX3i provides stable real-time control for sites maintaining legacy GE automation infrastructure. ESD protection must be observed while handling the GE CPU310 RX3i to protect onboard chips and memory components.
