Seeed Technology Co.,LtdRelay Shield | 103030009

Description

The Relay Shield provides the ability control high current devices that cannot be controlled by Arduino’s Digital I/O pins because of its limits on current and voltage. It features four high quality relays that provide NO (Normally Open)/NC (Normally Closed) interface.

The Relay Shield also includes four LEDs to display the on/off state of each relay. The standardized shield form factor makes it a smooth connection to the Arduino/Seeeduino board or other Arduino compatible boards.

Cautions:

Make sure to place 2 layers of electrical tape on the top of the Arduino’s USB connector as this will prevent the relay shield from making contact.

Do not operate voltage more than 35 VDCC.
