E8516-051 WOODWARD Debugger unit

The E8516-051 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 E8516-051
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:
- E8516-051 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.

What is residual pressure controller

The network-based residual pressure monitoring system consists of four parts, including residual pressure detector

CS-Y03N (also known as residual pressure sensor or differential pressure controller), residual pressure controller CS-Y04C,

residual pressure monitor CS-Y04M, and pressure relief valve actuator.

The residual pressure controller can receive signals from the residual pressure detector and perform centralized processing to

control the electric actuator of the pressure relief valve, thereby controlling the opening and closing of the bypass pressure relief valve.

The residual pressure controller can provide centralized power supply to the residual pressure sensor CS-Y03N (residual pressure detector)

and the electric actuator (bypass relief valve control mechanism), and provide real-time feedback of on-site information to the residual pressure monitor CS-Y04M.

1、 Product features of residual pressure controller CS-Y04C

1. Monitor the status of the residual pressure detector and adjust the pressure relief valve in conjunction with the residual pressure detector;

2. Fire protection dual bus communication and power supply are used between the residual pressure detector, and only NHRVS-2 × 1.5 mm ² communication line is used;

3. The multifunctional button can query the total number, working status (running, alarm, fault), and pressure relief valve status of all residual pressure detectors in this circuit;

4. Chinese LCD display screen, compact product design, fully functional;

5. Each circuit can carry 256 residual voltage detectors.
