5441-409 Woodward ProTech 203

The 5441-409 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 5441-409
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:
- 5441-409 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.

3. Electronic gear and electronic cam function

Electronic gears and electronic camshafts can greatly simplify mechanical design and achieve many functions that are difficult to achieve with

mechanical gears and camshafts. Electronic gears can achieve synchronous movement of multiple motion axes according to the set gear ratio,

which makes motion controllers well suited for fixed length cutting and off-axis rotation color printing.

In addition, the electronic gear function can also enable a motion axis to follow a function with a set gear ratio, which is determined by the motion

of several other motion axes; One axis can also follow the composite speed of the other two axes in a set proportion. The electronic cam function can

change the cam shape through programming, without the need to grind the mechanical cam, greatly simplifying the machining process. This function

makes the motion controller well applied in fields such as quenching of mechanical camshafts, cutting of irregular glass, and full motor driven springs.

4. Compare output function

When the position reaches the set coordinate point during the motion, the motion controller outputs one or more switch values without affecting the

motion process. In AOI flight detection, the comparative output function of the motion controller enables the system to run to the set position and start CCD rapid

imaging without affecting the motion, greatly improving efficiency and image quality. In addition, in laser engraving applications, the function of the universal motion device of Gu Gao Technology has also been well applied.
