Each relay is protected by a fuse. Granted, the fuse is hard-soldered to the board; so if you blow the fuse, you'll have to de-solder and re-solder a new fuse in place, but that's not a huge problem. Protects each circuit from drawing more than the 2 amps that the relay is rated for.The signal from the Arduino doesn't cut on the relay directly. Instead, the signal from the Arduino turns on a transistor, which closes a circuit that turns on the relay. The relay itself is optocoupled; so there is plenty of electrical isolation between the Arduino board and the relay. No worries at all on my part about frying my Arduino board.Each relay draws about 10 milliamps from the Arduino when switched on. If you're only turning on a few relays at the time, that is not a problem for the Arduino to... Less

The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. Which means it could be a nice solution for controlling devices that couldn't be directly controlled by Arduino's Digital I/Os. Standardized shield form factor enables smoothly connection with the Arduino. The shield also has four dynamic indicators show the on/off state of each relay.Caution:Place 2 layers of electrical tape on the top of theArduino's usb connector. This will prevent the relay shield from making contact. Do not operate voltage more than 35V DC.
