Application of PLC

A PLC(Programmable logic controller) is a type of logic controller that is used to control and monitor different electromechanical processes in manufacturing, plant, sensors, actuators, and other automation applications. In addition to being employed as a special-purpose digital computer, the PLC may be used in a number of control system domains and industries. This is why PLCs are often known as industrial computers.
