1. Model Breakdown

GE: Brand (Former GE Fanuc Automation, currently part of Emerson)
IC695: Unified prefix for modules of PACSystems RX3i platform
CRU: Redundancy Central Unit, redundant central processing unit
320: Base model designation, equipped with 1GHz Celeron M processor
NE: Hardware revision/suffix variant; identical core hardware functions to standard IC695CRU320
RX3i: Name of PACSystems RX3i large-scale PAC automation control platform
Redundancy CPU: Redundant Central Processing Unit

IC695CRU320 is the base part number. IC695CRU320-NE is a revised variant with identical functionality.

High-performance Hot Standby redundant CPU designed for GE RX3i platform, supporting primary/standby dual-CPU redundant architecture.
Equipped with a 1GHz Celeron M processor, 64MB battery-backed user memory and 64MB non-volatile flash memory to execute automation control logic.
Works with IC695RMX128 / IC695RMX228 synchronization modules to realize high-speed data mirroring between primary and standby CPUs.
In case of primary CPU failure or power loss, the standby CPU performs bumpless automatic switchover with minimum switchover time of 3.133 ms to maintain uninterrupted operation. Manual switchover is also supported.
Communicates with local I/O modules via backplane bus. Integrated RS232/RS485 serial ports support Modbus RTU, SNP and other protocols for connection with HMIs and supervisory computers.
Supports multiple programming languages: Ladder Diagram, Structured Text, Function Block Diagram and C language.
Provides built-in hardware self-diagnosis, fault alarming, program upload/download and real-time clock management.
Can operate as a single standalone CPU, or deployed in pairs to build high-availability redundant control systems.

Serves GE PACSystems RX3i automation control systems, targeting mission-critical processes where downtime is unacceptable.
Widely deployed in thermal power, hydropower, oil & gas, chemical plants, water treatment, metallurgy and key production lines of heavy manufacturing.
Acts as the core controller of redundant systems to execute continuous process interlock logic, sequence control and data acquisition.
Commonly adopted in DCS subsystems, auxiliary unit control systems, pump station control and compressor control systems.
Eliminates single-point failure risks caused by CPU faults, improving stability and safety level of factory automation systems.
