Woodward 8200‑1312 505XT Digital Turbine Governor Controller

Woodward 8200‑1312 belongs to the 505XT series, a microprocessor‑based digital governor controller for steam turbines and industrial turbine‑generator units. It integrates speed regulation, extraction‑admission control, load control, unit start‑stop sequence and fault‑protection functions, supporting configurable parameters for different turbine working conditions.

This controller comes with built‑in graphical HMI touch‑screen and keypad for local operation and diagnosis. It supports multiple communication interfaces, and obtains ATEX Zone2 and marine‑approval certifications, adapting to power‑plant and offshore hazardous‑area environments. It is widely used as replacement spare‑part for on‑site troubleshooting, equipment maintenance and turbine‑control‑system retrofit projects.
