5466-425 Woodward overspeed protector

The 5466-425 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5466-425
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5466-425 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

Signal processing: The motor controller processes the detected signal, including filtering, amplification, conversion, and other operations,
to extract useful information while ensuring the accuracy and stability of the signal.

Drive signal output: Based on the detected signal and control requirements, the motor controller will output corresponding drive signals to
control the motor”s operating speed, direction, acceleration and other parameters, and ensure the accuracy and stability of the drive signals.

Overload protection: When the motor is overloaded or in other abnormal situations, the motor controller will immediately stop outputting
the drive signal to protect the safety of the motor and other system components.

Fault diagnosis: The motor controller can also diagnose faults in the motor system, detect the type and location of faults, and provide corresponding fault handling methods.

3、 Types of motor controllers

There are various types of motor controllers, which can be classified into the following types based on different control objects and requirements:

AC motor controller: suitable for controlling the operation of AC motors, by changing the input AC voltage and frequency to change the speed and direction of the motor.

DC motor controller: used to control the operation of a DC motor by changing the input DC voltage and current to alter the motor”s speed and direction of rotation.

Stepper motor controller: used to control the operating parameters of the stepper motor, moving the rotor of the motor by controlling the current and pulse signals.
