What is an actuator?
An actuator is an electromechanical device used to operate or control something.
(e.g a motor or a valve)
-An actuator is used in controlling applications
-When energised, an actuator can operate or control a system (for example, a solenoid could be used to operate a plunger or control a fuel injection system)
- A digital to analogue (DAC) converter is some time required to control an actuator. A computer (or microprocessor) is connected with the actuator and data sent to it will go through the DAC when being transmitted to the actuator.
