A relay holding circuit diagram is used to keep the relay in the energized state even after the control signal is removed.

• The circuit typically includes a holding contact that maintains the relay coil energized.

• A latching relay can also be used for holding without continuous power supply.

• Examples: ladder logic diagram with a holding contact, latching relay circuit diagram.

PNP and NPN are types of bipolar junction transistors commonly used in electronic circuits.

• PNP transistor has a layer of N-type semiconductor between two layers of P-type semiconductor, while NPN transistor has a layer of P-type semiconductor between two layers of N-type semiconductor.

• In a PNP transistor, current flows from the emitter to the base and then to the collector, while in an NPN transistor, current flows fro...read more

There are various types of sensors used for different purposes.

• Temperature sensors (e.g. thermocouples, thermistors)

• Pressure sensors (e.g. piezoelectric sensors)

• Motion sensors (e.g. accelerometers, gyroscopes)

• Proximity sensors (e.g. ultrasonic sensors)

• Light sensors (e.g. photodiodes, phototransistors)

PLC stands for Programmable Logic Controller, which is a digital computer used for automation of electromechanical processes.

• PLC is used to control machinery in manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability control.

• It is programmed using a specialized computer language, typically ladder logic or function block diagram.

• PLCs are commonly used in industrie...read more
