Product Description
Woodward 8200-1503 (505D) Digital Governor is a dedicated digital controller of Woodward 505D series for steam turbines. Adopting microprocessor architecture, it integrates speed control, load control, pressure control and unit safety protection functions. It supports automatic unit start-stop, valve regulation and critical speed avoidance. Equipped with abundant configurable I/O interfaces and built-in fault self-diagnosis, it can connect with DCS control system via multiple communication protocols. The front panel supports local parameter configuration, status monitoring and operation, serving as the core control component for industrial turbine equipment.
