5464-332 Woodward ProTech 203

The 5464-332 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 5464-332
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:
- 5464-332 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.

Automotive Distributed EEA

In order to solve these problems of distributed EEA, people have gradually integrated many ECU functions that are similar or separated into

a processor hardware platform with stronger performance than ECU, which is the automotive “Domain Control Unit (DCU)”. The emergence of

domain controllers is an important milestone in the evolution of automotive EE architecture from ECU distributed EE architecture to domain centralized EE

architecture (as shown in Figure 2-2).

The domain controller is the core of every functional domain in the automotive industry, mainly composed of three parts: the domain main control processor,

the operating system, and application software and algorithms. Platformization, high integration, high performance, and good compatibility are the main core

design ideas of domain controllers. By relying on high-performance domain controller processors, abundant hardware interface resources, and powerful software features, domain controllers can integrate core

functions that originally required many ECUs, greatly improving system functionality integration. In addition, standardized interfaces for data exchange can greatly reduce

the development and manufacturing costs of this part.

For the specific division of functional domains, each automotive host manufacturer will divide them into several different domains based on their own design concepts

. For example, BOSCH is divided into five domains: Power Train, Chassis, Body/Comfort, Cockpit/Entertainment, and ADAS.

This is also the most classic five domain centralized EEA, as shown in Figure 2-2. Some manufacturers further integrate the five domain centralized architecture, merging the

original power domain, chassis domain, and body domain into the vehicle

control domain, thus forming a three domain centralized EEA, namely: Vehicle Control Domain Controller (VDC), ADASAD Domain Controller (ADC), and Cockpit Domain

Controller (CDC). Both Volkswagen”s MEB platform and Huawei”s CC architecture belong to this three domain centralized EEA.
