A relay is an electrically operated switch that is commonly used in various electrical and electronic circuits. Among its many applications, the 220V AC relay plays a crucial role in controlling high voltage devices using low voltage control signals. This type of relay is designed specifically for use in systems where 220V alternating current (AC) is the primary power source, and it enables the safe and efficient operation of these systems by controlling electrical connections without direct manual intervention.
What is a 220V AC Relay? A 220V AC relay is an electromechanical switch that uses an electromagnetic coil to open or close a set of contacts, thus allowing or interrupting the flow of electrical current in an AC circuit. The relay operates by energizing the coil with a low voltage control signal (usually 12V or 24V DC) to activate or deactivate the contacts in the high-voltage AC circuit. This makes it possible to control high-power devices such as motors, heaters, and lights with a much lower control voltage, offering a higher level of safety and convenience in managing electrical systems.
