The Woodward 9907-14 is a digital I/O expansion module designed for 505/505XT speed control systems, providing enhanced interface capabilities for industrial turbines and engines.
Key Features & Parameters (Typical Specifications):
Function: Overspeed detection and shutdown protection for turbines, engines, or rotating machinery.
Input Signal: Typically receives speed input from a magnetic pickup (MPU) or proximity sensor.
Speed Setting Range: Adjustable, often in RPM (e.g., 500–20,000 RPM, depending on configuration).
Output: Relay contacts for alarm or shutdown signals (usually SPDT or DPDT).
Power Supply: Commonly 24V DC or other industrial voltage levels.
Accuracy: High precision, often ±1 RPM or better.
Response Time: Fast reaction to speed deviations (milliseconds range).
Environment: Designed for harsh industrial conditions (temperature, vibration, EMI resistance).
Typical Applications:
Gas turbines
Steam turbines
Diesel engines
Compressors & pumps
Power generation systems
