It is necessary to protect the machine in industry. Because machine is main source of production of industry. Here we have put lamp instead of motor. When one lamp (motor) run at time there is no chance to run another motor by manually. Students can easily understanding the basic concept of protection system. Relay logic is employed in this project.
This project basic concept of saving of energy. Here simple demo working model of wiring concept. In this demo model contain four room and each room have light. When person go one to another room there will no need to light on first room, so here done typical wiring of two way switch concept. When person ON another room switch automatically first room switch OFF.
A PLC can be define as a digitally operating electronic apparatus which uses a programming memory for the internal storage of instructions for implementing specific function such as logic, sequencing, timing, counting, and arithmetic to control through digital or analog modules and various type of machine process
A transistor amplifier which raises the power level of the signals that have audio frequency range is known as transistor audio amplifier. It is used in constant current source, Fm Demodulation, Frequency multiplication and division.
Railway gate control system (conventional), human efforts are necessary and digitalization is not possible. But by digitalizing this system using sensors and electronics circuit we can remove the human efforts or it can say very less human effort is used.
