6945-377

WOODWARD 6945‑377 is a main power supply module / digital microprocessor control unit for Woodward 505 series turbine governor control systems, manufactured in the USA. It is the core power supply and control core of steam/gas turbine speed‑load controllers, responsible for providing stable power for the governor system and executing turbine speed regulation, actuator drive and safety interlock logic. Widely used in thermal power, petrochemical, compressor and marine power turbine control systems.

Description

Product Details

This module converts industrial AC/DC power into stable regulated power for the 505 governor motherboard and I/O circuits, with built‑in over‑voltage, over‑current and short‑circuit protection.
It integrates basic microprocessor control logic, matches Woodward I/H electro‑hydraulic converters, converts electrical control signals into hydraulic signals to drive turbine main steam valves/fuel valves, realizing precise turbine speed and load closed‑loop control.
Industrial‑grade hardware features strong anti‑electromagnetic interference, anti‑vibration and wide‑temperature adaptability; compact plug‑in design supports quick installation and replacement, with real‑time power status monitoring and fault self‑diagnosis functions.
