Relays are essential components in electrical and electronic systems, often used to control high-power circuits with low-power signals. A relay electrical diagram serves as a vital tool in understanding the working principle and the operation of a relay within a circuit. In this article, we will explore the significance of relay diagrams, how they function, and the importance of proper diagram interpretation for effective circuit design and troubleshooting.
What is a Relay? A relay is an electrically operated switch that allows the control of a high-voltage or high-current circuit using a low-voltage or low-current signal. It consists of an electromagnet, a set of contacts, and a spring-loaded mechanism. When a current flows through the coil (electromagnet), it generates a magnetic field that attracts the armature, thus closing or opening the contacts. This action enables the relay to control devices like motors, lights, and other appliances without direct electrical contact with the high-power side of the circuit.
