8200-226 Woodward turbine controller

The 8200-226 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 8200-226
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:
- 8200-226 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.

Working principle of microcontroller
Today, the shadow of microcontrollers can be seen in a large variety of products. If your microwave oven has light-emitting diodes,

LCD screens, and operation buttons, then it is equipped with a microcontroller. Nowadays, all cars are equipped

with at least one microcontroller, some up to six to seven: the engine, anti lock braking system, and cruise control all rely on the control

of the microcontroller. Almost any device equipped with a remote control is equipped with a microcontroller: televisions, video recorders, and high-end stereo systems

all belong to this category. You should have some understanding of precision DSLR cameras, digital cameras, mobile phones,

portable cameras, telephone answering machines, laser printers, telephones with caller ID and number storage functions, pagers, fully functional refrigerators

, dishwashers, washing machines, and dryers with display screens and operating keyboards. In general, any product or device that requires interaction with users has a built-in microcontroller.
In this article, we will explore microcontrollers to help you understand their nature and working principles. Afterwards, we will further introduce how to personally

use the microcontroller. Let me reveal in advance that we will be making a digital clock with a microcontroller! In addition, we will also create a digital thermometer.

Throughout the process, you will learn a lot about how microcontrollers can be applied to commercial products.
