Product Description The Woodward 5466-316 is a high-density “Combo” module designed for use in MicroNet and NetCon 5000 turbine control systems. It is a versatile I/O solution that integrates speed sensing, analog measurement, and actuator driving into a single card slot. This module is specifically engineered for high-speed turbine applications, featuring dual-core processing for real-time control and built-in filtering for speed signals. It utilizes a Field Terminal Assembly (FTM) for simplified wiring and is “calibration-free,” meaning modules can be swapped in the field without requiring manual potentiometer adjustments.
Application Areas This module is primarily found in Steam Turbine and Gas Turbine control systems. It excels in:
- Speed Monitoring: Precise measurement of turbine shaft speed for overspeed protection.
- Actuator Control: Driving proportional fuel valves or steam valves via high-current actuator outputs.
- Process Feedback: Monitoring temperature, pressure, and flow via 4-20 mA analog loops.
- Surge Prevention: Managing high-speed compressor control in industrial plants.
Product Specifications

- Dimensions: 25.0 cm x 24.5 cm x 2.5 cm
- Country of Origin: USA
- Update Time: Software selectable filter time constants (8 ms or 16 ms)
Operational Precautions
- Input Configuration: There are two distinct hardware versions of the 5466-316; one is fixed for 4-20 mA and the other for 0-5 V analog inputs. Verify your specific hardware revision before connecting field sensors to avoid signal errors.
- Static Discharge: This module contains sensitive CMOS components. Always use an ESD wrist strap and discharge static electricity from your body before handling the board.
- Speed Range Calibration: The maximum speed detected is software-dependent. Ensure the speed range in the application software is correctly scaled to your turbine’s operational limits to avoid false “loss of speed” trips.
- Cabling: Use shielded twisted-pair cables for all speed and analog signals. Keep these low-voltage signal lines separated from high-voltage power cables to minimize electromagnetic interference (EMI).
