Woodward 8400-016 Electrically Powered Governor (EPG) - Precision Speed Control Solution
The Woodward 8400-016 EPG actuator delivers reliable electronic speed control for diesel and gas engines in demanding industrial environments. Engineered with 24 VDC operation and 30-degree rotational travel, this electrically powered governor ensures consistent performance across power generation, marine propulsion, and industrial drive applications.
Technical Specifications
- Model: 8400-016
- Supply Voltage: 24 VDC
- Rotational Travel: 30° (0.52 radians)
- Control Signal: 4-20 mA or 0-10 VDC input
- Response Time: <100 ms full stroke
- Operating Temperature: -40°C to +85°C
- Protection Rating: IP65 environmental sealing
- Mounting: Standard SAE flange interface
Key Applications & Use Cases
Power Generation: Maintains precise RPM control in diesel generator sets from 50 kW to 3 MW, ensuring stable frequency output and load sharing in parallel configurations.
Marine Propulsion: Provides throttle control for auxiliary engines and emergency generators on commercial vessels, meeting SOLAS and classification society requirements.
Industrial Drives: Controls engine speed in pump drives, compressor packages, and mechanical drive systems where electronic precision replaces mechanical governors.
Solution Benefits
This EPG actuator replaces traditional mechanical governors with electronic precision, eliminating wear-prone components like flyweights and springs. The closed-loop feedback system maintains ±0.25% speed regulation under varying loads, while the fail-safe spring return ensures safe shutdown during power loss.
Integration with Woodward digital controllers (505E, easYgen series) enables advanced features including load sharing, droop compensation, and remote setpoint adjustment via Modbus RTU or CANopen protocols.
Frequently Asked Questions
Q: Can the 8400-016 replace mechanical governors on existing engines?
A: Yes, the SAE standard mounting flange allows direct retrofit on most diesel and gas engines originally equipped with mechanical governors. Verify shaft rotation direction and linkage geometry before installation.
Q: What control signals are compatible?
A: The actuator accepts 4-20 mA current loop (most common), 0-10 VDC voltage, or PWM signals when configured with appropriate interface modules.
Q: Is external position feedback required?
A: The 8400-016 includes an integrated potentiometric position sensor providing 0-5 VDC feedback proportional to shaft angle, eliminating the need for external transducers.
Q: How does it handle power interruptions?
A: A built-in spring mechanism returns the actuator to the minimum fuel position (idle or shutdown) within 200 ms of power loss, ensuring safe engine operation.
Warranty & Support
Backed by a 12-month manufacturer warranty covering defects in materials and workmanship. Technical support includes installation guidance, calibration procedures, and troubleshooting assistance from certified Woodward service centers worldwide.
