Description

The GE ACC-5595-208 (also referenced as 350-805595-208) is a high-performance Redundant CPU Controller Module for GE’s RX3i PACSystems, engineered for mission-critical applications demanding zero-downtime operation. As a fault-tolerant pair, these modules operate in synchronized lockstep, executing identical control logic simultaneously while continuously cross-monitoring for discrepancies. Should the primary CPU (ACC-5595-208) detect a fault, control seamlessly transfers to the secondary module within milliseconds – ensuring uninterrupted process integrity in power generation, oil & gas safety systems, and continuous manufacturing. Built on Intel multi-core architecture, the ACC-5595-208 delivers robust processing power for complex ladder logic, motion control, and data logging while supporting high-speed deterministic I/O scanning. Its integration with Proficy™ Machine Edition software streamlines programming and diagnostics. The GE ACC-5595-208 is more than a controller; it’s a resilience backbone that eliminates single points of failure, maximizes plant availability, and safeguards high-value industrial processes against catastrophic disruptions.

Technical Specifications

Main Features and Advantages

Deterministic Fault Tolerance: The GE ACC-5595-208 sets the benchmark for high-availability control. Its hardware-synchronized redundancy architecture uses a dedicated fiber-optic link to maintain<1ms>

High-Performance Processing: Leveraging an Intel quad-core processor, the module handles complex control strategies – including PID loops, data analytics, and motion coordination – while maintaining deterministic sub-millisecond scan times. The integrated 1GB DDR3 RAM supports extensive data logging and buffering for OEE tracking or audit trails.

Seamless Integration & Diagnostics: The ACC-5595-208 integrates natively with GE’s Proficy Machine Edition software, providing intuitive tools for configuration, online monitoring, and diagnostics. Engineers can force I/O, trace logic execution in real-time, or analyze fault logs without halting operations. The module’s front-panel LEDs provide immediate visual status (RUN, OK, FAULT, SYNCH) for rapid health assessment.

Future-Proof Design: Backward compatibility with legacy RX3i I/O modules (IC695* series) protects existing investments. Support for embedded Ethernet/IP enables direct connectivity to HMIs, SCADA, and MES layers, while optional PROFINET modules future-proof communications with modern field devices.

Application Field

The GE ACC-5595-208 excels in industries where unplanned downtime equates to significant revenue loss or safety risks. In power generation, it governs turbine control systems (TMR configurations), boiler protection logic, and grid synchronization – where milliseconds matter. Oil & gas facilities deploy it for critical Safety Instrumented Systems (SIS), managing emergency shutdown (ESD) valves, fire & gas detection, and compressor station control, leveraging its SIL 3 capability when properly configured.

Continuous process industries like chemical manufacturing rely on the ACC-5595-208 for reactor batch sequencing, distillation column control, and hazardous material handling, where its redundancy prevents runaway reactions. Water/wastewater treatment plants use it for pump station control and floodgate management in geographically dispersed SCADA networks. In automotive manufacturing, it synchronizes high-speed robotic assembly lines and paint shop environmental controls, ensuring production continuity despite component failures. Essentially, any application requiring “five-nines” (99.999%) availability or compliance with functional safety standards benefits from the GE ACC-5595-208‘s engineered resilience.
