LECTURE 3: Actuators, Encoders, Relays and Switches. Actuators: An actuator is the device that brings about the mechanical movements required for any physical process in the factory. Internally, actuators can be broken down into two separate modules: the signal amplifier and the transducer. The amplifier converts the low power control signal into a high power signal that is fed into the transducer, which actually converts the amplified control signal into the required form of energy.
