Product Overview

The GE IC695CRU320 is a high-performance, redundancy-enabled central processing unit designed specifically for the PACSystems RX3i platform. This module is the core component for industrial operations requiring zero-downtime tolerance, functioning as a "Hot Standby" controller. In a redundant configuration, two IC695CRU320 units work in a synchronized primary/secondary pair. If the active processor encounters a fault, the backup unit assumes control seamlessly, ensuring that critical processes continue without interruption.

Equipped with a 1GHz Celeron M processor and a robust PCI-based backplane interface, the IC695CRU320 delivers high-speed logic execution and significant data throughput. It is engineered to manage complex automation architectures, supporting expansive I/O counts and sophisticated control algorithms required in power generation, oil and gas, and large-scale water treatment facilities.

Advanced Fail-Safe Operation

The IC695CRU320 stands out in the PACSystems lineup for its deterministic performance and fault-tolerant design. By utilizing the high-speed PCI bus on the RX3i Universal Backplane, the module achieves significantly faster data exchange rates compared to traditional serial-bus controllers. This architecture allows the system to synchronize massive amounts of process data between the primary and secondary racks in real-time.

From a maintenance perspective, the module supports "Hot Swapping," allowing hardware replacements without powering down the entire system—a vital feature for mission-critical Distributed Control Systems (DCS). With the ability to store up to 512 program blocks, the IC695CRU320 provides the scalability needed for future plant expansions while maintaining the rigorous safety and availability standards required by modern industrial infrastructure.
