The Relay Shield provides four high-quality relay that can control high current loads to Arduino / Seeeduino boards. The onboard NO (Normally Open) / NC (Normally Closed) interface could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/Os.

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) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/Os. The standardized shield form factor enables a 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 fan, light, motor or high current DC actuators like solenoid valve, etc...

The Relay Shield provides a solution for controlling high current devices that cannot be controlled by Arduino’s Digital I/O pins due to current and voltage limits.
Hi Joe, This product will be back in stock at April 10. Please stay tuned. Thanks for your time and interest in Seeed.
So I just looked at a close up of the relays in the pic and answered half my question. ;) Now just need to make sure it works with an Uno Rev3 board.
YES！Relay Shield v3.0 is compatible with Arduino/Genuino 101
