The Arduino 2-Relay Shield R2 lets the Arduino board turning on/off up to two systems, such as TV, audio equipment, lights, and other electrical devices that consume 7A/250VAC, 10A/120VAC or 10A/24VDC. Ideal for automate home/office/other appliances.

Arduino 2-Relay Shield can also capture up to 2 digital signals of 3VDC max. and read them from the Arduino board. The inputs are opto-coupled and were directed to the 0 and 1 interrupt pins, so it can capture events in real time.

This shield comes with a Reset button for easy access and firmware reboot. The Arduino 2-Relay Shield connects to the Arduino board without needing any wires and leaves the pin layout intact, allowing a second Shield to be connected on the top.

The Arduino 2-Relay Shield uses the 2, 3, 6, 7 and RESET pins for communication with the board so it can change the relay status or read a digital signal. As long as this Shield is being used, these pins cannot be used for other purposes. The Shield comes with 5mm Terminal Block connectors for easy connection.

This board does NOT include header pins for Arduino connection. We recommend 6-pin and 8-pin stackable headers.
