5405-818 Woodward speed control module

The 5405-818 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 5405-818
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:
- 5405-818 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.

Working voltage:

The main power supply of the fire linkage controller generally uses 220V AC voltage; The backup power source is a DC power

source, powered by batteries, with a supply voltage of generally 24-32V

. When powered by AC, the grid voltage is between 85% and 110% of the rated voltage (220V).

When the frequency fluctuates within the range of 50Hz ± 1Hz, the fire linkage controller should be able to work normally.

The voltage stability and load stability of its output DC voltage shall not exceed 5%.

3) Electromagnetic compatibility:

The electromagnetic compatibility of the fire linkage controller refers to the adaptability and stability of the fire linkage controller under electromagnetic interference environmental conditions,

which should comply with the relevant provisions of the current national standard GB16806 “Fire Linkage Control System”.

4) Security performance:

The safety performance of the fire linkage controller refers to the electrical safety performance of the fire linkage controller in use, which should

comply with the relevant provisions of the national standard GB16806 “Fire Linkage Control System”.

3、 Engineering application

The engineering design, construction, and acceptance of the fire linkage controller shall comply with the relevant provisions of the current national standards

GB50116 and GB50166. In terms of selection and use, cabinet, desktop, and wall mounted fire linkage controllers should be selected according to the characteristics

of the usage location, system scale, and user needs. Wall mounted fire linkage controllers are commonly used in small and medium-sized fire linkage control systems;

For large-scale or ultra large scale fire linkage control systems, cabinet or desktop fire linkage controllers should be selected. Corresponding forms of fire linkage controllers

should also be selected based on the usage environment conditions and certain special requirements. Explosion proof fire linkage controllers should be selected for

environments that are prone to explosion hazards; Marine fire linkage controllers should be selected for marine use.
