Key Features

1. Precision Servo Valve Control: Delivers high-resolution analog outputs to regulate electro-hydraulic servo valves, ensuring accurate control of fuel flow, steam valves, and turbine speed.
2. TMR & Simplex Compatibility: Supports both single-channel simplex and triple-modular redundant (TMR) system configurations, providing fault tolerance and zero downtime during component failures.
3. High-Speed Real-Time Processing: Equipped with a 667 MHz PowerPC processor and QNX OS, enabling fast closed-loop control and deterministic response to dynamic turbine load changes.
4. Redundant & Wide-Range Power: Accepts 18–36 V DC redundant power inputs, ensuring stable operation even with voltage fluctuations or single power supply failures.
5. Comprehensive I/O Interface: Includes 2–3 servo outputs, 2 pulse rate inputs (for speed/position sensors), and digital communication ports for seamless integration with Mark VI/VIe I/O packs and HMI systems.
6. Harsh Environment Durability: Features conformal coating, industrial-grade components, and robust VME connectors to withstand extreme temperatures, vibration, and electrical transients.
7. Integrated Diagnostics & Status Monitoring: Three front-panel LEDs (Run, Fail, Status) provide real-time operational visibility, while onboard diagnostics detect and report faults to the control system for proactive maintenance.

Application Scenarios

• Power Generation Plants: Deployed in gas turbine, steam turbine, and combined-cycle power plants for critical control of fuel valves, steam inlet valves, and turbine governor speed; ensures stable, efficient power generation under varying grid loads.
