The Woodward 9905-973 is a specialized analog speed control module that serves as a key component in governor systems for industrial prime movers. This module utilizes analog electronic circuitry to maintain precise speed control of engines and turbines by continuously comparing actual speed (measured through magnetic pickups or tachogenerators) with a predetermined setpoint. It generates appropriate output signals to adjust fuel metering devices or actuators, ensuring stable operation during load changes, startups, and shutdowns. The module is designed for integration with Woodward's governor systems and features robust construction suitable for industrial environments, with enhanced resistance to electrical noise and temperature variations. Typical applications include speed regulation of diesel engines in power generation sets, gas turbines in compressor stations, and industrial steam turbines. The 9905-973 maintains Woodward's tradition of reliability in analog control technology, providing consistent performance without requiring digital programming or complex configuration.
