Description
Woodward 9907-167 505E Digital Turbine Speed Controller
1. Product Overview
The Woodward 9907-167 is a high-performance digital speed controller designed for industrial steam turbines, part of the 505E series. It supports single extraction/steam admission control, making it ideal for applications such as generators, compressors, and pumps. With a 32-bit microprocessor, it delivers precise speed, load, and pressure regulation. The controller features a NEMA 4X-rated enclosure (optional) for durability in harsh environments. While now discontinued, Woodward recommends upgrading to the 505 XT series (e.g., model 8200-1310) for enhanced performance and compatibility.

5. Competitor Comparison
Compared to similar controllers, the 9907-167 stands out for its seamless integration with existing Woodward systems, advanced safety features, and cost-effective retrofitting capabilities. Its modular design allows for easy expansion, while competitors often require complex hardware modifications.
6. Selection Recommendations
- Compatibility: Ensure compatibility with your turbine’s actuator type (single/multi-stage).
- Environment: Opt for the NEMA 4X enclosure if exposed to outdoor or corrosive conditions.
- Budget: Consider the 505 XT series for long-term reliability, as the 9907-167 is no longer in production.
7. Precautions
- Installation: Follow proper grounding and shielding practices to prevent electromagnetic interference.
- Maintenance: Regularly inspect sensor alignment and update firmware for optimal performance.
- Safety: Always isolate power before servicing and adhere to hazardous area regulations.
