Relay is an electromagnetic device that is used to isolate two circuits electrically and connect them magnetically. They are very useful devices and allow one circuit to switch to another one while they are completely separate. They are often used to interface an electronic circuit (working at a low voltage) to an electrical circuit that works at very high voltage. These relays can be used for switching High voltage 250 Volt devices and has a current rating of up to 30 amperes. Ideal for use in your academic projects and for small device switching. Use them to switch high voltage (240AC), and/or high current devices(30A). FEATURES low power consumption coil PCB mounting high quality
