Description
Woodward 5417-027
Technical Specifications
- Input Interfaces: Features 16 discrete inputs (4 fixed, 12 programmable) and 6 programmable current inputs (4-20mA).
- Output Signals: Provides 0-10V DC analog output signals for driving actuators and valves.
- Communication: Equipped with RS-232 and Ethernet interfaces, supporting Modbus protocols.
- Dimensions & Weight: Approximately 15.2 cm x 5.1 cm x 20.3 cm, weighing about 0.7 kg.
Functional Features
- Speed & Load Control: Operates single extraction and/or admission of steam turbines using staged actuators to drive steam inlet valves for precise speed and load regulation.
- System Optimization: Supports multiple control modes, including speed control, load control, and synchronous control (isochronous mode).
- Real-Time Diagnostics: Features self-diagnostic capabilities to monitor performance data (speed, temperature, pressure) and issue fault alarms.
Application Scenarios
Ideal for power generation facilities and industrial plants requiring precise, automated control of steam and gas turbines, as well as turbo-expanders.
Performance Parameters
- Processing Technology: Utilizes high-precision digital algorithms for complex control logic, such as critical speed avoidance and valve limiting.
- Programmability: Supports field programming via a menu-driven software interface on the front panel.
Material Composition
Housed in a compact, industrial-grade enclosure with high-quality printed circuit boards featuring conformal coating for protection against environmental hazards.
Structural Characteristics
- Operator Panel: Integrated front panel with a two-line text display (24 characters per line) for easy parameter adjustment and monitoring.
- Compact Form Factor: Designed for space-efficient installation in dense control panels.
Working Principle
The microprocessor continuously samples analog and discrete inputs from the turbine. It processes this data using embedded control algorithms and outputs precise analog or discrete signals to the turbine’s hydraulic actuators to maintain the desired operating parameters.
Installation Requirements
Must be mounted securely in a climate-controlled environment. Ensure proper clearance for ventilation and easy access to the front operator panel.
Precautions for Use
Strictly observe electrostatic discharge (ESD) precautions during handling. Utilize the front panel display to monitor self-diagnostics and address any active alarms promptly.
