9907-994 Woodward ProTech 203

The 9907-994 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 9907-994
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:
- 9907-994 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.

Extended features
You can set more detailed management permissions for the registration card, including which doors can be accessed on a certain day of the week and from what time to what time.

You can remotely open a door through software, or force it to open or close.

The usage mode of mandatory card+password can be achieved through a password keyboard card reader.

It can be set to a multi card opening state, and all card holders must be present before the door can be opened. This is suitable for vaults, banks, or security and confidentiality institutions.

The alarm function can be activated to sound an alarm for illegal intrusion, prolonged unclosed doors, and coercion.

Anti submarine return and anti tailgating functions can be enabled to prevent following or handing over the card to others after entering.

Multiple levels of administrator permissions can be set, and different administrators have different levels of operational permissions.

Detailed parameters of access control controller
The access control data storage controller, abbreviated as the access control controller, adopts advanced international high-speed computing circuits and Flash massive storage technology

microcontroller design. It integrates processing, storage, and communication functions on a printed circuit board

and has the feature of quickly dismantling the same communication port terminal. The software monitors the communication activity of each port and uses a memory interface processing unit,

which can support microprogram control memory loaded by the higher-level station. The design of microcontrollers has inherent reliability, and the expansion of transient protection function

and automatic self checking function further enhances this reliability.

It can store offline the card reading information, time information, and current status information of the inductive IC card reader in Wiegand26 format. Widely used in induction IC card application

systems for access control, attendance, member management, customer management, parking lot management, etc.

Unlimited expansion space of high-speed intelligent ARM platform based on 32-bit CPU

40000 registered cards and 100000 records dominate the massive storage of products in the same class

Standard professional dual access control power supply ensures long-term stable operation of the system

Even with thousands of large-scale access control systems, card swiping records are instantly reported in real-time
