The Yocto-PowerRelay-V2 is a USB relay: it contains a USB-driven SPDT relay switch: you can drive by software the relay input to one of the two outputs. To make it easier to test your project, two leds positioned on each side of the connector show the output currently active.

This device only includes a single relay, but it can drive higher loads than the Yocto-Relay device. The relay and the connector can stand 250 VAC and a current of 5A. When put in an adequate enclosure, the Yocto-PowerRelay-V2 can be used to switch directly appliances connected to the mains. Be aware that using a relay to drive inductive loads (motors, transformers) may lead to accelerated aging of the relay. Please refer to the documentation for hints on reducing this type of problems.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
