Product Description
🧠 Emerson 5X00490G23 – OCR400 Ovation Controller Module
The brain of your distributed control system. The 5X00490G23 OCR400 is Emerson's flagship controller module, executing real-time control logic, managing I/O networks, and coordinating process automation across refineries, power plants, and chemical facilities worldwide.
🚀 Processing Power Meets Industrial Resilience
Built on a ruggedized architecture, the OCR400 runs deterministic control algorithms at millisecond scan rates while simultaneously handling operator interface communications, alarm management, and historian data logging. Dual-redundant processors ensure zero process interruption during controller failover—critical for continuous manufacturing operations.
🔍 What Makes OCR400 Different?
Distributed Intelligence: Unlike legacy PLCs that centralize control logic, the OCR400 distributes processing across multiple controllers, reducing network bottlenecks and improving system responsiveness. Each module manages its own I/O rack, executing control loops locally while sharing data via high-speed Ethernet.
Scalable from Day One: Start with a single controller managing 500 I/O points, then expand to multi-controller architectures handling 50,000+ tags without re-engineering your control strategy. The OCR400's modular design grows with your facility.
Cybersecurity by Design: Integrated firewall, encrypted communications, and role-based access control meet IEC 62443 industrial cybersecurity standards—protecting critical infrastructure from evolving threats.
🏭 Real-World Deployments
Crude Oil Refining: An OCR400 cluster manages distillation column temperature cascades, furnace firing controls, and product blending—coordinating 12,000 I/O points across a 200,000 bpd refinery. Redundant controllers maintain production during planned maintenance windows.
Combined-Cycle Power Generation: Controls gas turbine sequencing, heat recovery steam generators, and emissions monitoring systems. Sub-second response times prevent turbine trips during grid frequency disturbances.
Pharmaceutical Batch Processing: Executes ISA-88 batch recipes for API synthesis, managing reactor temperatures, pH control, and material transfers with full 21 CFR Part 11 audit trails.
Pulp & Paper Mills: Coordinates digester cooking cycles, bleaching sequences, and paper machine speed control—integrating with MES systems for production scheduling and quality tracking.
