Product description: Relay Shield v3.0 - relay board
Relay Shield v3.0 is a high quality relay board for regulating large load currents compatible with Arduino / Seeeduino with built-in LED indicators and screw terminals. Maximum switching current 15 A relay lifetime up to 100 000 cycles.
Relay Shield v3.0 thanks to its relays, which can be controlled directly from Arduino via digital leads. Shield has four LEDs that indicate the on/off status of each relay. These are useful for operating AC devices such as fans, lights, motors or high current DC actuators such as a solenoid valve etc.

Relay Shield v3.0 overlay pin description
| Pin | Description |
|---|---|
| COM1 | Pin of relay reference wire. |
| NC1 | The normally closed (NC) contact of the relay is connected to COM1 when the RELAY1 pin is set LOW; for RELAY1 to HIGH, the connection is broken. |
| NO1 |
NO contact (NO) of relay connects to COM1 when RELAY1 pin is set HIGH; connection is broken if RELAY1 is set LOW. |
| 4 digital pins |
4 digital pins to adjust 4 relays. |
| RELAY1 - RELAY4 |
Can be connected directly to Arduino Pin 7-4, allowing easy control of four relays with Arduino. |
