Woodward 701A Digital Speed Control
For Reciprocating Engines

The Woodward 701A Digital Speed Control offers improved speed control with models designed specifically for lowspeed to high-speed diesel, gas, or pilotfuel engines (one actuator moving two sets of linkages to the gas fuel valve and the diesel injection system).
The control has enhanced control dynamics that give smooth steady-state operation, yet the control retains fast response to engine speed and load changes.
An external contact input allows switching between two independent sets of automatic variable dynamics. This is especially useful for engine systems with different operation conditions, such as open or closed clutches or pilot-fuel engines. The contact could also be wired to change dynamics based on utility tie breaker status.
