The Relay4 Board is small-sized board with 4 Relays(each supports currents up to 16A). Also, it contains ULN2804 (high-current Darlington arrays) for relays driving and IDC10 connector for easier connecting with development or prototype board.
The Relay 4 Board is a cost-effective solution for adding relays to your device. Single ULN2803 driver IC with 8 Darlington arrays drives each of the four available relays. Screw-terminals allow you clean and easy output relay connectivity, and standard IDC10 connector is used for connection with development boards. Using this board with your MCU you can turn on 230V lightbulbs, DC motors, or any other device that draws up to 16A of current and up to 250V. This board allows your device to jump over the boundary of output digital signals into the world of higher voltages and currents. .
