Overview
The DYN1-10704-000-0-12 from Woodward’s Barber-Colman line is a DYNA 2000/2500 series speed governing module developed for consistent rotational speed control of diesel-driven systems and industrial turbines. This unit operates as a linear, two-state controller, ensuring stable engine response under varying load conditions.
Unlike integrated protection governors, this model is intended strictly for speed regulation and must be deployed alongside external safety shutdown devices in critical systems.

Safety and Integration Notes
This controller does not provide built-in protective shutdown features. For safe operation in industrial environments, the following external systems are mandatory:
- Independent overspeed trip device
- Overtemperature protection (engine-dependent)
- Pressure or lubrication safety interlocks where applicable
Failure to implement external protection may result in uncontrolled engine acceleration or equipment damage.
Typical Applications
- Diesel generator sets
- Mechanical drive systems
- Industrial pumps and compressors
- Small to medium-scale turbine control systems
FAQ
Q: Does this governor include overspeed shutdown functionality? A: No. The unit is strictly a speed controller. A separate overspeed protection system must be installed.
Q: Can this model be used with gasoline engines? A: Not recommended. For ignition engines, the DYN1-10724 variant is typically specified.
Q: Is field adjustment required during installation? A: Yes. Calibration is generally necessary to match engine characteristics and achieve optimal performance.
