Woodward 9907-164 Industrial Control Module

A critical component for precision turbine control systems, this module serves as the interface between digital control systems and mechanical actuation mechanisms. Its primary function involves translating control algorithms into precise analog/digital signals for governor systems in power generation and industrial machinery.

This module forms the core of Woodward’s 505/505E digital governor systems, commonly found in steam and gas turbine applications. In power plants we’ve supported, it’s typically paired with 9907-162 I/O modules and 9907-167 communication cards to create complete turbine control systems. One customer in Texas recently upgraded their coal-fired plant’s governor system using this module, achieving 0.25% speed regulation improvement.

Our inventory includes both standard and obsolete variants of Woodward control modules. For turbine control applications, we commonly handle 9907-164 units alongside related models like 9907-149, 9907-162, and 9907-167. We’ve recently helped several clients source replacement units for legacy 505 systems where original manufacturers had discontinued support.

Our Value Proposition

We maintain 16 regional warehouses across 6 countries with real-time inventory tracking. When a Canadian oil sands operator needed emergency replacement during scheduled maintenance, we delivered an 9907-164 unit from our Calgary warehouse within 8 hours – 36 hours faster than the manufacturer’s lead time.

• 12-month warranty covering both parts and performance
• Cross-reference assistance for obsolete module replacements
• Technical support from engineers with 15+ years average experience
• Custom testing available for mission-critical applications
