As industries are growing, so are the components (regarding numbers as well). Because of research and development, industry eyes at utilizing and bringing resources into practice. Let's talk about some of the most critical industrial components PLC (Programmable Logic Controllers) - A programmable logic controller (PLC) or programmable controller is a one of a kind industrial digital computer which has been improved to be hard-wearing and used to control the manufacturing process. At the same time, it at the same time monitors the state of the input devices and makes decisions by a custom program which then controls the state of output devices. Servo Motors - A servomotor is a rotary actuator which is used to control linear position, velocity, and acceleration. The motor is connected to a sensor for feedback. The other thing that it also requires is a controller which is a module designed to use with a servomotor. They are further used in applications like robotics, CNC machinery. Limit Switches -they are used for controlling machine parts of a control system or to count objects that are passing a point. It is electromechanical that consists of an actuator mechanically linked to a set of contacts. If an object comes in communication with the actuator, the device then can make or break an electrical connection. They can be used in a variety of applications because one can rely on their ruggedness for different operations. Motor starters - They are similar to relays but are electromechanical. Their primary function is to start and stop the motor to which they are connected. The main difference between a relay and a starter is that a starter contains overload protection for the motor. Variable Speed Drives (VSDs) - basically, they help in saving energy in plants that use powerful electric motors. They are also known as adjustable speed drives which are large industrial electric motors whose speed can be adjusted by an external controller. The use of adjustable speed in process control matches the motor speed to the required tasks and may compensate for changes in the process's variables. Medium Voltage Switchgear - Switchgear are used to stabilize the unsteady flow of power. Help in maintaining the irregular flow of energy. It acts as a shield to the interconnected devices by controlling and regulating the flow of electricity. It then contributes to the overall functions like operations, design, maintenance, machine control, etc. Push buttons- Unlike usual buttons; push buttons help employees control multiple aspects of a machine through a straightforward push button it can also be connected to other mechanical linkages. There are three types of push buttons- start, standard and stop. These different buttons allow for greater freedom and industrial functionality. Contactor - It is an electrically-controlled switch used for switching an electrical power circuit. It is typically controlled by a circuit, which has a much lower power level Apart from optional auxiliary low-current contacts, contactors are almost exclusively fitted with normally open ("form A") contacts
