Product details
Relay Card allows you to control the circuit of high voltage with a low voltage, say 5V from the Carduino. The relay on the Relay Card is normally-opened. You can connect any high voltage appliance through the 2-pin terminal block connector on the front of the board. A relay is an electrically operated switch used to control a circuit by a low-power signal. It allows for the safe and efficient operation of electrical systems by isolating control and load circuits, providing protection, and facilitating automation. In essence, relays are used to switch on or off high-power circuits with a low-power signal, which is crucial for various applications.
