Description

Woodward CPC-II9907-1199

Technical Specifications

  • Model: CPC-II 9907-1199.
  • Input: 4-20 mA isolated control signal.
  • Output: Linear pneumatic pressure.
  • Diagnostics: Built-in health monitoring and fault reporting.
  • Certifications: CE, ATEX, SIL-rated options available.

Functional Features

  • Enhanced Diagnostics: Reports internal valve health, supply pressure status, and output loop integrity.
  • Fail-Safe Logic: Configurable fail-safe position (up, down, or hold) upon fault detection.
  • High Accuracy: Superior linearity and repeatability for precise process control.
  • Vibration Immunity: Engineered to maintain performance in high-vibration environments.

Application Scenarios
Used in high-performance steam turbines, gas turbines, and critical process control valves where precise positioning is essential for efficiency and safety.

Performance Parameters

  • Resolution: Better than 0.05% of span.
  • Response Time: Adjustable for optimal control loop tuning.
  • Temperature Stability: Excellent performance across the full operating temperature range.

Material Composition
Premium-grade materials including anodized aluminum housing, stainless steel valve spools, and high-performance elastomer seals.

Structural Characteristics

  • Form Factor: Compact, panel-mount or direct-mount design.
  • Connectors: High-reliability multi-pin electrical connector.
  • Indicators: LED status indicators for power, signal, and fault conditions.

Working Principle
The module converts the 4-20 mA input signal into a proportional pneumatic output using a precision force-balance mechanism. The integrated diagnostics continuously monitor the valve position and internal pressures, reporting any deviations to the control system.

Installation Requirements

  • Follow all grounding and shielding guidelines for the input signal.
  • Ensure the pneumatic supply is clean and properly regulated.
  • Mount securely to prevent mechanical stress on the pneumatic connections.

Usage Precautions

  • Configure the fail-safe position to match the process safety requirements.
  • Monitor diagnostic alarms and address them promptly.
  • Perform regular calibration and functional tests.
