Datasheet

The Relay Shield provides four high quality relays that can control high current loads

to Arduino / Seeeduino boards. It also provides NO (Normally Open) / NC (Normally

Closed) contacts. A nice solution for controlling devices that cannot be directly

controlled by Arduino's Digital I/Os. Standardized shield form factor enables smooth

connection with Arduino and compatibles. The shield also has four LED indicators to

show the on/off state of each relay.

Relays are useful in switching on/off AC appliances like fans, lights, motors or high

current DC actuators like solenoid valves.
