WOODWARD DC10502-000-024 | Digital Speed Governor for Industrial Engines

Description

• The WOODWARD DC10502-000-024 is an all-electronic speed control device designed for precise regulation of diesel, gas, or gasoline-fueled engines. Operating on a 24 VDC power supply, this digital governor processes inputs from speed sensors and auxiliary control signals to manage fuel delivery precisely. It is engineered to replace older mechanical governor setups or analog controllers, offering superior response time, excellent stability under sudden load changes, and user-friendly digital programmability for improved emission and fuel efficiency.
  

  Technical Specifications (Datasheet)

  Part Number: DC10502-000-024 Manufacturer: Woodward Product Type: Digital Speed Governor / Engine Controller Operating Voltage: 24 VDC nominal (18–32 VDC range) Speed Input Signal: Magnetic Pickup (MPU) Frequency Input Enclosure Protection: IP56 / Sealed Industrial Housing Dimensions: 15.8 cm x 11.2 cm x 4.5 cm Weight: 0.65 kg Country of Origin: USA

  Application Fields

  This compact digital governing system is highly utilized across small to mid-sized engine applications:

  • Industrial Generator Sets: Maintaining exact electrical frequency (50/60 Hz) on standby and prime power systems.
  • Agricultural Equipment: Regulating engine RPM under fluctuating torque demands for heavy machinery.
  • Marine Auxiliary Power: Governing service diesel generators on commercial vessels.
  • Pumping Stations: Controlling engine speeds to maintain optimal flow rates in water and fuel pipelines.

  Product Usage Instructions

  1. Chassis Mounting: Mount the unit vertically in a dry area of the control panel. Ensure it is located away from high-temperature engine parts and strong ignition system noise.
  2. Wiring Configuration: Connect the 24 VDC power source to the correct power terminals. Use high-quality shielded twisted-pair cables for the Magnetic Pickup (MPU) inputs and ground the shield at one end only.
  3. Actuator Integration: Connect the controller output directly to the engine’s proportional actuator. Ensure the mechanical link between the actuator and fuel rack moves smoothly without friction or backlash.
  4. Parameter Configuration: Use Woodward configuration software or the interface buttons to set essential parameters such as Idle Speed, Rated Speed, and overspeed limits.
  5. PID Tuning: Start the engine and adjust the Gain and Stability parameters. Increase the Gain until the engine just begins to hunt, then turn it down slightly to secure crisp, stable governor response.

  Frequently Asked Questions (Q&A)

  Q: Can this governor operate on a 12V vehicle battery system? A: No, the DC10502-000-024 is explicitly designed for 24 VDC electrical networks. If used on a 12V network, the module will suffer from under-voltage faults and fail to drive the actuator.

  Q: What happens if the MPU speed signal is lost? A: The governor features an integrated fail-safe feature. If the speed signal drops completely, the unit instantly shuts off current to the actuator, cutting off fuel to prevent an engine runaway.

  Q: Is calibration required when changing the governor out? A: Yes. Every engine assembly has distinct dynamics. When swapping out a module, you must upload the application code or recalibrate the PID and speed settings to ensure safe operation.

  Q: Where can I look up specific availability and software tools for this part? A: You can find official documentation, support tools, and procurement options for the WOODWARD DC10502-000-024 by checking the industrial inventory at https://www.newplcdcs.com.
