An amplifier is a device that enhances the strength of signals, particularly in industrial automation, where it boosts control signals for motors, valves, actuators, and sensors. Various types of amplifiers, including voltage, current, power amplifiers, and operational amplifiers (op-amps), are employed for different tasks such as driving devices and processing signals. Op-amps, in particular, are versatile and used in feedback control systems and sensor interfaces.

1. What Is
Amplifier
?
Amplifier is a device that
boosts the strength of a
signal. In industrial
automation, amplifiers are used
to enhance the control signals
that govern the operation of
various components such as
motors, valves, actuators, and
sensors.

signals by increasing
their voltage levels.
They are commonly used
for driving motors,
actuators, and other
devices that require
voltage-controlled
inputs.

• Op-amps are versatile
amplifiers used for various
signal processing tasks,
including amplification,
filtering, and signal
conditioning. They find
applications in feedback
control systems,
instrumentation, and sensor
interfaces.
