3. Detailed Product Description

In complex industrial processes, precision in actuator positioning is paramount. Whether it’s a fuel valve on a turbine, a damper in a ventilation system, or a critical flow control valve, accurate and rapid response to control signals is essential for efficiency, safety, and performance. Manual adjustments are often impractical, and traditional drivers may lack the sophistication or diagnostic capabilities needed for modern, interconnected systems. This is precisely where the WOODWARD 8200-227 steps in, offering a smart and reliable solution for sophisticated servo control.

The WOODWARD 8200-227 is an integral component of Woodward’s Servo Position Controller (SPC) series. It’s not merely an amplifier; it’s an intelligent, field-programmable digital driver that bridges the gap between your main control system’s commands and the physical movement of proportional or integrating servo-valves and actuators. Its ability to communicate via CANOpen makes it an excellent choice for modern networked control architectures, ensuring efficient and reliable data exchange.

Key Features and Benefits

Precise and Responsive Actuator Positioning: The core strength of the 8200-227 lies in its ability to accurately and responsively position servo actuators. It accepts a position demand signal (primarily via CANOpen, or 4–20 mA as an alternative) from a system controller and precisely drives the connected servo-valve or actuator to the commanded position. This rapid and accurate response is crucial for maintaining tight control over critical process variables.

Robust CANOpen Communication: The integration of CANOpen communication makes the 8200-227 highly adaptable to modern industrial control environments. As a CANOpen slave device, it can be seamlessly commanded and monitored within a larger CANOpen network, simplifying wiring, enhancing data integrity, and providing flexible system architectures.

Flexible Feedback Options for Enhanced Accuracy and Redundancy: For precise valve position sensing, the SPC accepts feedback signals from various devices. It can handle feedback from one or two (for redundancy) AC LVDT/RVDT devices, or a single DC LVDT/RVDT/potentiometer. The capability to accept dual feedback signals allows the unit to switch to a healthy feedback signal if one fails, significantly enhancing the reliability and availability of the control loop.

Configurable and User-Friendly PC Interface: The 8200-227 is accompanied by a Windows-based PC interface software. This intuitive tool allows users to:

• Configure the SPC for specific actuator types and application requirements.
• Auto-calibrate the servo-valve, simplifying setup and reducing installation time.
• Dynamically adjust tuning parameters while the unit is operating.
• Monitor critical parameters in real-time.
• Manually stroke the controlled servo for testing and troubleshooting. Configurations can be uploaded and downloaded, facilitating easy deployment across multiple SPC units.

Comprehensive Protection and Diagnostics: Safety and reliability are paramount. The 8200-227 includes built-in protection features and provides clear alarm indications for various faults, such as:

• CANOpen communication time-out
• Analog input out-of-range
• Feedback open-wire or voltage out-of-range
• Position error
• Internal SPC faults
• Actuator open/short circuit
• Driver overcurrent A hard-wired shutdown contact input and relay driver output are also provided for interfacing with external protection circuits, ensuring layers of safety.

Compact and Robust Design: The SPC is designed for heavy industrial environments, suitable for bulkhead mounting in IP20 locations. Its compact footprint saves space in control cabinets, while its robust construction ensures reliable operation under demanding conditions.
