Description
The Woodward 8256-011 is a specialized Speed Control Module engineered as a core component of the EPG (Electric Power Generation) product family. As a dedicated fuel control system, it serves as the intelligent brain within a three-part governing architecture. By monitoring engine speed and modulating fuel flow with high precision, this unit ensures stable operation under varying electrical loads. Its primary mission is to maintain engine frequency consistency, which is vital for industrial power generation applications where strict adherence to speed setpoints is non-negotiable for system safety and power quality.

- Dimensions: 130 mm x 110 mm x 50 mm
- Origin: Primarily manufactured in the United States
Frequently Asked Questions
💡 How does the 8256-011 function within the three-part EPG system? The EPG system typically consists of the controller (like the 8256-011), an actuator, and a magnetic pickup. The 8256-011 acts as the control logic, receiving signals from the pickup and sending precise electrical currents to the actuator to adjust fuel rack positioning.
⚙️ Why is this model specifically important for speed control? It is built with enhanced circuitry to handle the rapid transient responses required during load steps. This allows the engine to recover to its rated speed significantly faster than standard mechanical governors, preventing voltage sags or spikes.
🛠️ What should I check if the engine exhibits speed instability? First, verify that the magnetic pickup is clean and gapped correctly. Then, check the stability and gain settings on the 8256-011 faceplate to ensure they are calibrated to your specific engine’s inertia and fuel system characteristics.
🌐 Is the 8256-011 field-programmable? While it is designed for ease of use, adjustments are generally made via analog potentiometers on the module. This traditional approach ensures high reliability and quick, intuitive adjustments on-site without needing specialized software interfaces.
