8405-020 | Electric actuator driver | With communication interface

The Woodward 8405-020 is an electric actuator driver manufactured by Woodward Governor Company. It is a key component in various control systems, especially in applications involving fuel or throttle control of engines or turbines.

Main functions:

Precise actuator control: The 8405-020 precisely controls the electric actuator, converting the control signal from the governor or controller into a proportional current that drives actuator motion.
Position feedback: It integrates position feedback from the actuator to ensure that the actuator position accurately reflects the desired control signal.
Fault detection and protection: The system monitors actuator and circuit failures, providing diagnostic information and preventing potential damage.
Communication interface: It has a communication interface that can be integrated with control systems, data loggers or remote monitoring devices.
Applications:

The Woodward 8405-020 is commonly used in a variety of applications where precise control of fuel or throttle position is critical:

Engine control systems: Manage the fuel supply and throttle position of diesel or gas engines for power generation, propulsion or industrial applications.
Turbine control systems: Regulate the flow of steam or gas to turbines for power generation or industrial processes.
Valve control systems: Control valves in a variety of industrial processes, such as flow control, pressure regulation or safe closing.
Technical specifications:

The detailed technical specifications of the Woodward 8405-020 May vary depending on the specific model, model, and application. However, some common specifications include:

Actuator compatibility: The type of electric actuator that the system can control, usually based on rated power, stroke length, and feedback signals.
Control signal range: The system can accept the range of electrical signals from the governor or controller.
Position feedback accuracy: The accuracy of the position feedback signal from the actuator.
Communication protocol: Communication interface protocol, such as RS-232, RS-485 or CAN bus.
Environmental rating: The ability of the system to withstand environmental conditions such as temperature, humidity and vibration.
