Smart Remote Actuators (SRAs)

Delphi Smart Remote Actuators (SRAs) come as electromechanical devices that actuate engine features, such as variable geometry (VG) and dual stage turbochargers, exhaust gas recirculation (EGR) valves and exhaust flap control valves. They also supply precise rotary position feedback to the engine control unit, which is provided either by a controlled area network (CAN-protocol), or pulse width modulation (PWM) signal. Integrated electronics enable software and calibration changes without modification of the electronic control unit's software algorithm. In un-powered conditions, the actuators will move into a default position.
