5501-367 WOODWARD Debugger unit

The 5501-367 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 5501-367
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:
- 5501-367 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.

Creating a digital clock

Spending $79 to make an LED light up seems a bit luxurious. You would definitely prefer to use BASIC Stamp to create something more practical

. For over 100 dollars, you can make an exquisite digital clock! This may seem too luxurious, but in the future when making various other devices,

you will find that these components can be reused.

We will use the input and output pins of BASIC Stamp to display numbers. In the digital clock section, we learned how to connect the 7-segment

display LED of the 7447 chip. The 7447 chip can work in conjunction with BASIC Stamp. By directly connecting the four input and output pins

of BASIC Stamp to 7447, it is easy to display numbers from 0 to 9. The BS-1 version of Stamp has 8 input/output pins, which can directly drive two 7447 chips.

For a clock, at least 4 digits need to be displayed. In order to drive 4 pieces of 7447 with 8 input/output pins, we need to be more creative.

The following figure provides a solution:
In the above figure, 8 input and output pins are introduced from the left. This method uses four input and output pins to drive all four 7447s.

The remaining 4 pins are used to activate 4 pieces of 7447 in sequence (the “E” on the chip represents “Enable Enable” – pin 5 on the 7447 chip).

To make this system work, the Stamp program first sends out the first number through four data lines and sets the E pin of the first 7447 to the first control line,

thereby activating 7447. Then issue the second number to activate the second piece 7447, and repeat the activation of the four pieces 7447 in sequence. In fact,

with a slight modification of the wiring, a single 7447 can achieve these functions. By using the 74154 multiplexer chip and some drivers, up to 16 digits can be driven using this method.

This is the standard method for controlling LED display screens in practice. If you have an old-fashioned LED display calculator, observe the display screen

while shaking it. You will find that only one number is lit up at the same time. This technology is called multiplex display.
