5501-428 Woodward turbine controller

The 5501-428 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 5501-428
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:
- 5501-428 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.

Basic Parameters

Communication method: TCP/IP

Supporting software: Simplified Chinese, English

Supported databases by supporting software: Access and SQL

Supporting chassis size: 273mm length * 228mm width * 65mm height Power supply: DC12V3A

Power input: AC110V or AC220V Operating temperature: -35 to 65 degrees Celsius

Operating humidity: less than 95% RH, no condensation

Extended functions:

The fire linkage door linkage door has an alarm if it is not closed for a long time, an illegal intrusion alarm, an illegal

card swiping alarm, and a coercion alarm function (if the fire and alarm linkage expansion board is not connected, it only

has a software interface alarm prompt and drives the computer speaker to give an alarm. If the expansion board is connected,

it has a hardware alarm output function and can drive devices such as lights or sirens). The forced door status is normally open

or normally closed, and the remote door opening function is available

Interlocking function (dual door and four door controllers have controller multi door interlocking function) Anti submarine return and anti tailgating function

Multi card simultaneous verification with door opening function, timed constant door opening function

Emergency door closing function (emergency double closing) with the first card opening the door

External password keyboard function (card+password, super pass password) for operators to manage permissions, departments, and areas, etc
