The Woodward 8200-1311 505-XT digital governor is a field-programmable steam turbine control system designed for single valve, split-range, extraction, or admission steam turbines in mechanical drive or generator applications. The 8200-1311 operates as a standalone unit or interfaces with a plant Distributed Control System (DCS) to manage steam turbine operation and parameter limiting. The device controls speed, load, inlet pressure, extraction/admission pressure, auxiliary parameters, exhaust pressure, and acceleration using integrated PID loops. Operating on AC or DC input power, this control system utilizes a built-in graphical user interface (GUI) with an integrated screen and keypad for system setup, online adjustment, and process parameter monitoring.
