8250-749 Woodward Ship Spare Parts

The 8250-749 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 8250-749
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:
- 8250-749 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.

Access control controller parameters

The commonly used communication methods for access control controllers include RS232, RS485, and TCP/IP.

The access control controller that uses RS485 for communication is the RS485 access control controller. RS485 access control controller is

a type of access control that can communicate with computers and can be directly managed using software, including card and event control.

So it has convenient management, centralized control, the ability to view records, and the ability to analyze and process records for other purposes.

The characteristic is that the price is relatively high and the installation and maintenance difficulty is increased, but the training is simple and value-added services

such as attendance can be provided. Suitable for projects with a large number of people,

high mobility, and multiple doors.

Basic functions of access control controller
It is possible to set access management permissions for 20000 personnel. You can set who can enter which doors.

It can monitor the opening and closing status of all doors and the entry and exit status of personnel, and display the personnel information of relevant card holders.

It is convenient to report lost cards.

All entry and exit records can be queried and printed.

It is convenient to conduct attendance statistics, statistics, and print detailed attendance reports and statistical reports through access control records. And it can also set the working hours,

clock in frequency, leave requests, holidays and National Day holidays, overtime hours range, forgotten clock in and sign in, etc.

It can be used offline, that is, software or computer can be accessed normally without turning on, and the entry and exit situation can be recorded. Even if there is a power outage, data will not be lost.

You can set the valid usage date and time period for the card.

The system clock can be calibrated online. It can store 20000 accessible permissions and 100000 accessible records offline.
