The Woodward 9905-867 is a steam turbine digital control designed for single-valve or single-valve rack steam turbines. Equipped with a 16-bit, 12MHz microprocessor, this microprocessor-based system provides speed control, dual dynamics, and integrated monitoring functions. The unit accepts redundant magnetic pickup speed inputs and features an analog input dedicated to remote speed setting or process control integration. Enclosed in a NEMA 4X rated housing, the 9905-867 provides field configuration capability for mechanical drive applications including pumps, fans, blowers, and compressors.
