Applications
The ProAct™ Analog product line is a family of electric actuators intended to be mounted on-engine
to control varying functions including (but not limited to): fuel rack positioning, timing control,
throttle valve, and wastegate positioning. The actuator is effectively a positioner with an
integral driver, which will accept a position command signal from
another device in the system such as a speed control.
In addition, the ProAct Digital Plus actuators include an integral digital
driver capable of controlling the actuator, communicating with the outside control
system, and containing on-board software and intelligence to realize monitoring and
customizing functions.
