Description
Woodward 8528-0015
Technical Specifications:
- Brand: Woodward
- Model: 8528-0015
- Product Type: Actuator Interface Module
Functional Features:
- Signal Amplification: Boosts low-level control signals to drive high-power actuator coils or motor drives with high fidelity.
- Position Feedback Processing: Accurately conditions LVDT or potentiometer feedback signals for closed-loop position control.
- Fault Detection: Monitors actuator circuit integrity, detecting open coils, short circuits, and feedback failures for proactive maintenance.
Application Scenarios:
Used in steam turbine valve control, gas engine fuel metering, and industrial process valve automation systems requiring precise position regulation.
Performance Parameters:
- Drive Capability: Sufficient current and voltage headroom for demanding actuator loads.
- Linearity: High linearity between input command and actuator position for accurate process control.
- Bandwidth: Wide frequency response for fast dynamic actuator performance.
Material Composition:
High-reliability power electronics with robust thermal design, housed in a shielded enclosure to prevent EMI interference with sensitive control signals.
Structural Characteristics:
Compact module design with screw-terminal or plug-in connections for power, control input, actuator drive, and feedback signals. Includes adjustment trimmers for calibration.
Working Principle:
Receives a position command from the controller, compares it with actual position feedback, and generates a drive signal proportional to the error. Built-in protection circuits safeguard against overcurrent and overtemperature conditions.
Installation Requirements:
Mount away from high-heat sources and vibration points. Use twisted-pair wiring for feedback signals and shielded cables for drive outputs. Ensure solid grounding of the module chassis.
Usage Precautions:
Calibrate actuator stroke and feedback alignment during commissioning. Periodically verify drive output and feedback accuracy. Do not bypass fault detection circuits during operation.
