3. Detailed Product Description:

 

For applications demanding both precision and significant power in actuator control, the WOODWARD 5501-1432 stands out within Woodward’s control system portfolio. This module is engineered to handle the needs of larger or more sensitive actuators commonly found in critical power generation and industrial processes.

The 5501-1432 is a 2-channel Actuator Driver Module that plugs into a compatible Woodward control chassis. Each of its two channels can independently control a proportional or integrating type of actuator. What sets it apart from lower-current modules (like the 5501-1429 with ±30 mA output) is its ability to deliver a significantly higher output current, typically up to ±245 mA. This higher current capability allows it to directly drive actuators that require more power for precise positioning, such as larger fuel valves or steam admission valves in large turbine systems.

The module incorporates essential features for robust closed-loop control:

  • Position Feedback: It accepts input from position feedback devices such as Linear Variable Differential Transformers (LVDTs) or Rotary Variable Differential Transformers (RVDTs). This real-time feedback allows the module and the main CPU to constantly compare the actuator’s actual position with the desired command, ensuring exceptional accuracy and enabling the detection of mechanical issues.
  • Software-Selectable Output Modes: The 5501-1432 offers flexibility, allowing it to be configured via software to operate in either an integrating mode (for actuators that require a continuous change in current to maintain position, or where the change in current determines speed of movement) or a proportional mode (where the output current is directly proportional to the commanded position).
  • Comprehensive Diagnostics: The module includes built-in diagnostics and fault monitoring. It can detect and report various errors related to excitation, feedback, and the actuator driver itself. This functionality, often indicated by a red fault LED on the module’s front panel, is crucial for rapid troubleshooting and ensuring system reliability. Specific fault conditions like excitation loss, feedback signal out of range, or driver overcurrent can be detected.

This module is designed for the rigorous demands of industrial environments, contributing to the overall reliability and safety of the control system. It often works in conjunction with dedicated Field Terminal Modules (FTMs) for simplified wiring connections to the actuators and their feedback devices.

 

Key Features and Benefits:

 

  • 2 Independent Control Channels: Provides versatile control for two separate actuators or redundant control for a single critical actuator.
  • High-Current Bi-Polar Output (±245 mA): Capable of driving more demanding actuators, ensuring precise and powerful control.
  • Software-Selectable Output Type: Configurable for either integrating or proportional control, adapting to various actuator types and control strategies.
  • Position Feedback Input: Accepts LVDT/RVDT signals for accurate closed-loop position control.
  • Robust Fault Diagnostics: Comprehensive monitoring of excitation, feedback, and driver health, with fault indications for rapid troubleshooting.
  • Industrial Hardened Design: Built to withstand harsh operating conditions, ensuring long-term reliability.
