3. Brand History
Woodward, Inc., founded in 1870 and headquartered in Fort Collins, Colorado, USA, is a global leader in energy control systems. The company has a long history of innovation in turbine control, engine management,
and power generation systems.
Woodward products are widely recognized for their reliability and precision in demanding industrial and power generation applications.
4. Applications in Industrial Automation
The 5463-834 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
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.
