A 220V AC relay is an indispensable component in the automation and control of electrical systems, especially in high-voltage applications. These relays allow low-voltage circuits to control the operation of high-voltage devices such as lights, motors, and household appliances. In this article, we will delve into the structure, working principle, and applications of 220V AC relays to help you understand their crucial role in modern electrical systems.
What is a 220V AC Relay? A 220V AC relay is an electrical switch that is activated by a low-voltage signal to control the flow of current in a higher-voltage circuit, typically 220V AC. It consists of a coil, contacts, and an armature that makes or breaks the connection between the contacts when the relay is energized. This allows an operator to control a high-power device using a low-power signal, which is often generated by a microcontroller, timer, or automated control system. Components of a 220V AC Relay The primary components of a 220V AC relay include： Coil： The coil is an electromagnet that, when energized with a current, generates a magnetic field. This field causes the armature to move and changes the state of the contacts.
