General Electric IC695CRU320 CPU Processor Module

The GE IC695CRU320 is a high-performance central processing unit built for the PACSystems RX3i architecture. It specifically enables high-availability configurations through integrated redundancy logic. This module allows two independent controller racks to function as a synchronized pair. Consequently, the secondary unit takes over control instantly if the primary hardware encounters a fault. This “hot standby” capability makes it essential for mission-critical infrastructure and continuous manufacturing lines.

Superior Processing and Synchronization

An Intel Celeron M 1 GHz processor drives the computational core of this module. This high-speed clock rate facilitates the rapid execution of dense logic programs. To maintain system alignment, the CPU supports a high-bandwidth synchronization link. This link transfers up to 2 MB of state data during every scan cycle. Because of this efficiency, the backup processor always holds an identical copy of the process image.

Ultra-Fast Fault Recovery

The IC695CRU320 delivers industry-leading failover speeds to prevent process interruptions. Switchover typically occurs within a single logic scan. Under optimal conditions, the transition completes in just 3.133 milliseconds. This performance level ensures that field actuators and valves do not drop out during a CPU transfer. Furthermore, the unit supports Ladder Diagram (LD), Function Block Diagram (FBD), and C programming.

System Integration and Migration

The module occupies a single slot on the RX3i Universal Backplane. It communicates over the high-speed PCI bus to minimize I/O latency. Additionally, the RX3i platform allows users to incorporate legacy Series 90-30 I/O modules. This feature provides a cost-effective path for upgrading older control systems. The CPU also includes a hardware port for easy connection to HMI panels or programming terminals.

Durable Design and Application

This redundancy processor excels in environments requiring maximum fault tolerance. It operates reliably in power plants, water treatment facilities, and oil refineries. The 64 MB of non-volatile memory protects critical user data during power loss. Meanwhile, the compact 0.36 kg housing fits easily into standard industrial control cabinets. This robust build quality ensures long-term operational stability in high-heat and high-vibration areas.
