- Flexible Control: Supports single or split-range actuators for steam turbine inlet valves, adapting to diverse system requirements.
- Critical Speed Avoidance: Automatically bypasses unsafe speed ranges to prevent mechanical damage.
- Real-Time Monitoring: Tracks parameters like speed, temperature, and pressure with 1 ms resolution.
- Modular Design: Expandable via additional I/O modules for complex control scenarios.
- Fault Tolerance: Built-in diagnostics and first-out shutdown indicators reduce downtime.
- Power Generation: Optimizes steam turbine performance in thermal power plants.
- Oil & Gas: Controls turboexpanders in gas processing facilities.
- Manufacturing: Manages rotating machinery in industrial automation lines.
Case Study:
A European power plant reduced maintenance costs by 30% using the 9907-164 to automate turbine speed control and detect early signs of component wear.
Compared to similar controllers:
- Wider Input Voltage Range: Operates at +24 VDC, reducing reliance on voltage regulators.
- Enhanced I/O Flexibility: Offers 16 contact inputs vs. typical 8–12 in mid-range models.
- Integrated Safety: Combines control and protection functions in a single module, minimizing system complexity.
- System Complexity: Choose the 9907-164 for multi-actuator systems requiring split-range control.
- Environment: Opt for IP56-rated models in harsh conditions (e.g., dusty or humid environments).
- Scalability: Pair with Woodward’s 8440-2028 I/O modules for future expansions.
- Grounding: Ensure proper grounding to prevent EMI interference.
- Firmware Updates: Regularly update via Woodward’s LeoPC software for compatibility and bug fixes.
- Power Supply: Use a filtered power source to avoid voltage spikes.
- Installation: Mount vertically in a vibration-free environment away from high-power cables.
