2. Product Overview:

The WOODWARD 5501-1429 is a 2-channel Actuator Controller Module that operates within Woodward’s industrial control systems (often part of the MicroNet or NetCon series). It’s designed to provide precise control signals to actuators, which in turn manipulate elements like fuel valves or steam valves on critical machinery. A key characteristic of this particular module is its ±30 mA output capability and its ability to handle feedback from position devices (like LVDTs/RVDTs) and detect faults. The module supports both integrating and proportional control modes, selectable via software.

• Product Type: Actuator Controller Module / Actuator Driver
• Manufacturer: Woodward
• Channels: 2 channels
• Output Current: Typically ±30 mA (bi-polar)
• Function: Controls proportional or integrating, pneumatic or hydromechanical actuators.
• Key Features: Feedback input (LVDT/RVDT), fault detection and latching, software-selectable output type.

3. Detailed Product Description:

Accurate and responsive control of fuel, steam, or other process flows is paramount for the efficient and safe operation of turbines, engines, and other critical industrial machinery. The WOODWARD 5501-1429 is purpose-built to deliver this precise control within Woodward’s sophisticated digital control platforms.

The 5501-1429 is a 2-channel Actuator Controller Module designed to plug into a compatible Woodward control chassis. Each of its two channels can independently control a proportional or integrating type of actuator, whether it’s a pneumatic or hydromechanical design. The module’s ±30 mA (milliamperes) output current capability provides the necessary power and resolution to drive these actuators with high precision.

A significant feature of the 5501-1429 is its ability to accept position feedback from devices like Linear Variable Differential Transformers (LVDTs) or Rotary Variable Differential Transformers (RVDTs). This feedback is crucial for closed-loop control, allowing the module and the main CPU to continuously verify the actuator’s actual position against its commanded position. This ensures accurate control and can help detect mechanical issues.

The module also incorporates fault detection features, including feedback fault latching. This means it can identify errors related to excitation, feedback, and actuator driver issues. A red fault LED on the module’s front face provides visual indication of its status, aiding in rapid troubleshooting. For example, a solid LED might indicate a communication loss with the CPU, while a flashing LED points to an internal module problem.

The 5501-1429 offers software-selectable output modes, meaning it can be configured to operate as either an integrating or proportional output, depending on the requirements of the actuator and the control strategy. This versatility makes it suitable for a wide range of control applications.

Key Features and Benefits:

• 2 Independent Control Channels: Allows for control of two separate actuators or provides redundancy for a single critical actuator.
• Versatile Actuator Control: Capable of controlling both proportional and integrating, pneumatic or hydromechanical actuators.
• Bi-Polar Output (±30 mA): Provides precise current output for accurate actuator positioning.
• Position Feedback Input: Accepts LVDT/RVDT feedback for closed-loop control and enhanced accuracy.
• Comprehensive Fault Detection: Monitors for excitation, feedback, and driver errors, with fault latching for improved diagnostics.
• Diagnostic LED: Provides quick visual status indication for troubleshooting.
• Software Selectable Modes: Allows configuration for integrating or proportional output based on application needs.
