A relay is an electrically operated switch used to control a high-power circuit with a low-power signal. It typically consists of an electromagnet, a movable armature, contacts, and a spring. When an electric current passes through the electromagnet, it generates a magnetic field that pulls the armature, closing or opening the contacts. This allows for the control of larger currents and voltages using a small input signal, making relays essential components in automation, protection systems, and remote control applications.

    Understanding Relay Electrical Diagrams

    Relay electrical diagrams provide a visual representation of how a relay functions within a circuit. These diagrams often include several components, such as power supplies, relays, switches, and load circuits, all interconnected in a specific configuration. The purpose of these diagrams is to show how the relay will control the flow of electricity to different parts of the circuit.
