WOODWARD 8200-541

الوصف

The WOODWARD 8200-541 is a Digital Valve Positioner (DVP). This sophisticated electronic device is crucial for providing precise and dynamic control over the position of electric valves and actuators in various industrial applications, particularly within gas and steam turbine control systems.

WOODWARD 8200-541: Digital Valve Positioner (DVP)

The WOODWARD 8200-541 DVP acts as an intelligent interface between a turbine’s main control system and its mechanical actuators. It accurately translates electrical command signals into precise physical movements, enabling highly dynamic and accurate control over critical parameters like fuel flow, steam flow, or other process variables.

Product Overview

This particular part number represents a specific configuration within Woodward’s advanced DVP series, known for its robust performance and flexibility in demanding industrial environments.

• Product Type: Digital Valve Positioner (DVP) / Electric Actuator Driver
• Manufacturer: Woodward
• Part Number: 8200-541
• Key Specifications (based on common configurations for this P/N):
  • Input Power: 24 VDC (typically 18–36 VDC).
  • Ingress Protection (IP) Rating: IP66. This is a significant feature, indicating robust protection against dust ingress and powerful jets of water. This makes it suitable for direct installation in more exposed industrial environments where moisture or dust might be present.
  • Input/Output Connections: Features Conduit Input/Output, meaning electrical wiring connections are made via conduits, offering enhanced physical and environmental protection for the wiring.
  • Communication: This specific variant (8200-541) is listed as No Ethernet, indicating that its primary control signal interface is likely analog (e.g., 4–20 mA, 0–5 VDC) or CANopen, rather than Ethernet Global Data (EGD).
  • Safety Integrity Level (SIL): This model is listed as Non-SIL, meaning it’s designed for high-reliability control functions but is not certified for safety instrumented functions where SIL compliance is required as the primary protection layer.
  • Motor Types: Compatible with Woodward’s Limited Angle Torque (LAT) and Brushless DC (BLDC) motor types, which are commonly found in their high-performance valves and actuators.
  • Position Feedback: Relies on resolver feedback from the valve or actuator for highly accurate and continuous position monitoring.
• Function: The 8200-541 DVP receives a demand signal from a turbine or plant control system (e.g., a Woodward MicroNet or 505 controller). It then processes this signal in real-time, combining it with high-resolution position feedback from the actuator, to precisely drive the valve to the commanded position. Its powerful internal controller uses advanced algorithms (such as PID and adaptive OptiTune) to ensure rapid, accurate, and stable valve control, which is essential for maintaining turbine stability, efficiency, and safety during all operating conditions.

Detailed Product Description

The Woodward 8200-541 Digital Valve Positioner is a robust and highly capable driver. It’s engineered for applications that demand precise control and reliable operation even in challenging environments.

• High-Speed, Accurate Control: The DVP uses advanced control algorithms and high-speed processing to accurately and rapidly position valves and actuators. This dynamic response is crucial for stable turbine operation, especially during transients like load changes and rapid startups, where very tight control is needed.
• Integrated Control Architecture: Built on Woodward’s latest control architecture, it provides reliable and efficient control for their range of electric motor-driven valves and actuators.
• Resolver Feedback for Precision: By using resolver feedback from the connected valve or actuator, the DVP establishes a highly accurate closed-loop control system, ensuring precise positioning, excellent repeatability, and minimal overshoot.
• ID Module Compatibility for Simplified Setup: Many newer Woodward valves and actuators come with an integrated “ID module.” When connected to the 8200-541 DVP, it can automatically read critical, valve-specific configuration information. This “plug-and-play” capability significantly simplifies installation, setup, and commissioning, reducing manual configuration errors.
• Robust IP66 Enclosure with Conduit Connections: The IP66 rating is a key advantage, making this DVP exceptionally resilient to environmental factors (dust and powerful jets of water). This expands its installation flexibility, allowing it to be placed directly in harsher environments without needing an additional protective enclosure. The conduit input/output further enhances the protection of the wiring, ensuring long-term reliability in challenging conditions.
