The DPG-2223-00X digital controller is used primarily to govern diesel or gas-fueled engines of generator sets. This microprocessor-based, digital controller performs across a wide speed range and allows adjustment of all controller features through the built-in user interface. Finely tuned, this controller delivers fast engine response to speed or load change while providing precise stable isochronous operation.

ProAct™ ISC combines the proven ProAct electric actuator with integrated speed control software to control the speed of diesel and gaseous fuel engines. ProAct ISC is a microprocessor-based speed control incorporated into an actuator, creating a single integrated actuator/speed control. This eliminates the need for an additional driver box and speed control box.

ProAct ISC can also be configured as a position control only device for basic actuator applications, accepting 4–20 mA, 0–5V, -3V to +3V, or CAN position command signals.

The ProAct ISC control uses state-of-the-art speed sensing and control algorithms. It also performs comprehensive diagnostics for easy troubleshooting. The ProAct ISC is configured and tuned using the ProAct ISC Service Tool.

The modular bi-directional actuator design easily attaches to fuel pumps, fuel valves, or throttle bodies.

Electrically powered governor (EPG) systems are designed for precise speed control of diesel, gas, gasoline engines, and gas turbines. They are especially suited to prime movers without a mechanical drive or hydraulic oil supply for the governor and which have low-mass, low-friction fuel linkages.

The 512/524 and 1712/1724 EPGs are three-component governing systems for 12 or 24 Vdc operation. All EPG systems include an actuator, an electronic speed control, and magnetic pickup.

The Woodward L-Series Integrated Engine Control System is the first engine speed control to deliver so much in a package this compact. It can also deliver substantial savings in production and field support. Since the L-Series Control System is microprocessor-based, it can easily be programmed to match the operating parameters of every engine you produce. The L-Series offers speed control with software-selectable speed setpoints, dynamics, fuel limiting, and start/stop behavior. All it takes is a PC and a simple plug-in download on your production line.

The F-Series ITB is designed to throttle air or air/fuel mixtures for gaseous engines in industrial and on-highway service. This system is designed for direct replacement of traditional throttle valves, and requires no linkage between valve and actuator. The ITB contains a return spring to fully comply with US DOT 571.124 specifications. The three sizes are designed to cover a wide range of engines, and should be selected using the sizing procedure described in this specification.

Woodward’s 2301E provides load sharing and speed control of generators being driven by diesel or gaseous engines. With built-in flexible configuration software, application variations can now be selected using an external computer (PC). Changing the application to accommodate engine speed range, gear teeth, and selection of forward or reverse acting is simply a matter of software setup. The 2301E controller is backward compatible with existing 2301D products.

DYNA 2000 and DYNA 2500 linear actuators provide precise positioning with a minimal number of moving parts. Many of the moving parts normally associated with electric actuators are eliminated, prolonging the mean time between failure.

These DYNA actuators are suitable for installation on diesel, gasoline, or natural gas engines with fuel system force requirements of less than 13 pounds (58 N) of force. When paired with a Woodward controller, precise isochronous speed control of 5 to 30 HP engines (DYNA 2000) and 5 to 60 HP engines (DYNA 2500) is achieved.
