8230-568 Woodward turbine controller

The 8230-568 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 8230-568
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:
- 8230-568 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.

This technology has great applications in clocks and calculators, but there are two important issues:

Light emitting diodes consume a large amount of power.

The 7-segment display LED can only display numbers.

Another method is to use a liquid crystal display screen. LCD displays are widely used and easily connected to Stamps. For example, the two

line alphanumeric LCD display shown in the figure below can be purchased from Jameco (part number 150990) and Parallax (part number 27910). Here

is a typical LCD display screen, which is plugged into a breadboard for easy connection with other chips:
The advantages of this type of LCD display screen are:

One pin can drive the display. The display screen contains logic circuits that allow Stamp to communicate with itself in a serial manner, so only one

pin is needed. In addition, the SEROUT command in BASIC Stamp can easily achieve serial communication and control the display screen is very simple.

LCD screens can display alphanumeric text, including letters and numbers, and even custom characters.

LCD displays have extremely low power consumption – only requiring 3 milliamps of current.

The only downside is that such a LCD screen costs $59. Obviously, no one would install such a display screen on an oven. When designing an oven,

such a display screen is usually used for sample testing first, and then a cheap display screen is driven by a chip and software designed by oneself for the final product.

To drive such a display screen, you only need to provide a power supply of 5 volts or more and a ground wire (Stamp”s 9-volt battery meets these two

conditions), and then connect one of Stamp”s input-output pins to the display input line. The easiest way I can find to connect the input and output

pins of Stamp to devices like LCD screens is to use Jameco”s wiring tool (part number 34577) and a 30 gauge connector (part number 22541).

This does not require welding and the connection is sturdy and reliable.
