Key Features

1. Multi-Signal Processing: Handles a wide range of analog signals including temperature (thermocouple), pressure (4–20 mA), vibration, and position (LVDT) for comprehensive turbine monitoring.
2. High Precision: Integrates high-resolution analog-to-digital (ADC) and digital-to-analog (DAC) converters for accurate signal conversion and control output.
3. Configurable PROM Modules: Equipped with removable PROM modules for easy firmware updates and configuration customization without replacing the entire board.
4. Robust Industrial Design: Conformal coating for protection against dust, moisture, and corrosion; designed to withstand EMI, thermal cycling, and vibration in harsh industrial environments.
5. Seamless System Integration: Connects to the Mark V system via backplane and IONET, supporting redundant communication for enhanced system reliability.

Application Scenarios

• Power Generation: Gas/steam/hydro turbine control systems for monitoring temperature, pressure, vibration, and position parameters; supporting startup, load regulation, and overspeed protection.
• Oil & Gas: Turbine-driven compressor and pump control in refineries, pipelines, and LNG facilities.
• Process Industries: Chemical, petrochemical, and pharmaceutical plants requiring precise analog signal monitoring and control.
