WOODWARD 8200-536

الوصف

The WOODWARD 8200-536 is a Digital Valve Positioner (DVP). This highly advanced electronic device is specifically designed for providing precise and dynamic control over the position of powerful electric valves and actuators in critical industrial applications, particularly within gas and steam turbine control systems.

WOODWARD 8200-536: Digital Valve Positioner (DVP) – High Output (10kW)

The WOODWARD 8200-536 DVP serves as a robust driver, translating electrical command signals from a turbine’s main control system into exact physical movements of the connected fuel, steam, or other critical flow control components. Its “High Output” designation, specifically 10 kW, indicates it’s built to handle the demands of very large, heavy, or fast-acting electric actuators, making it suitable for the most challenging control applications.

Product Overview

This particular part number represents a specialized and high-capacity configuration within Woodward’s DVP product line, optimized for maximum power delivery and sophisticated control.

• Product Type: Digital Valve Positioner (DVP) / Electric Actuator Driver – High Output
• Manufacturer: Woodward
• Part Number: 8200-536
• Key Specifications:
  • Input Power: 24 VDC.
  • Output Power: This is a crucial distinguishing feature. The 8200-536 is a 10 kW High Output DVP. This means it can supply up to 10 kilowatts of power to operate extremely demanding electric actuators.
  • Ingress Protection (IP) Rating: Typically IP30. This indicates protection against solid objects larger than 2.5 mm, but no protection against water. It’s designed for installation inside a control cabinet or a well-protected enclosure.
  • Input/Output Connections: Features Terminal Block (TB) Input/Output. All electrical connections for control signals, power, and feedback are made via screw terminals.
  • Communication: This specific variant (8200-536) is listed as including Ethernet communication (likely supporting Ethernet Global Data, EGD). This enables advanced connectivity to plant Distributed Control Systems (DCS) and other network-based systems.
  • 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 strict 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 integral to 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 8200-536 DVP receives a demand signal from a turbine or plant control system (e.g., a Woodward MicroNet or 505 controller, potentially via Ethernet). It then processes this signal in real-time, integrating it with high-resolution position feedback from the actuator, to precisely drive the valve to the commanded position with immense power. Its powerful internal controller utilizes 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, especially in applications where very large and fast-acting valves are required.

Detailed Product Description

The Woodward 8200-536 Digital Valve Positioner (High Output) is a robust and highly capable driver, specifically engineered for the most demanding control applications that require significant electrical power for valve actuation.

• Exceptional Power Output (10 kW): This DVP’s standout feature is its ability to deliver a massive 10 kW of power to the connected actuator. This makes it ideally suited for driving the largest and heaviest electric valves that demand substantial force for precise and rapid movement, crucial in large-scale power generation or industrial processes.
• High-Speed, Accurate Control: It incorporates advanced control algorithms and high-speed processing to accurately and quickly position valves, even under challenging dynamic conditions. This responsiveness is critical for maintaining stability during rapid load changes and precise regulation.
• Integrated Control Architecture: Built upon Woodward’s cutting-edge control architecture, it provides reliable and efficient control for their range of electric motor-driven valves and actuators, specifically designed for both LAT and BLDC motor types.
• Resolver Feedback for Precision: By utilizing 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 8200-536 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.
• Ethernet Communication: The inclusion of Ethernet provides a modern, high-speed interface for seamless integration into plant-wide control networks. This facilitates remote diagnostics, monitoring, and control, enhancing overall system management and enabling more sophisticated control strategies.
• Robust and Reliable Design: Despite its sophisticated internal electronics, the DVP is built for durability in industrial environments. Its IP30 rating guides its installation within protected enclosures to ensure long-term reliability.
