Webb25 mars 2024 · Here, for the timer circuit, two transistors are replaced with a single BC517 Darlington pair. This circuit has much simple circuitry and double-times duration as that of the second circuit. The operating voltage of all three circuits is 12V. To operate the circuit at a low voltage of 5-6V, the relay with the same voltage rating has to be selected. WebbRelays have many benefits for the systems and users. Some of them are: 1. Simple and effective operation. The operating principle of a relay is really simple. The current flowing through the coil of the relay creates a magnetic field that attracts a lever and changes the switch contacts. Thus, it allows controlling a device remotely.
