The Yocto-PowerRelay-V3 is a USB power relay. It contains a robust 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 show the output currently active. This device only includes a single relay, but it can drive higher loads than the Yocto-Relay and the Yocto-PowerRelay-V2. The relay and the connector can stand a current of 5A, and when put into an enclosure, the Yocto-PowerRelay-V3 can be used to directly switch appliances connected to the mains, up to 250 V AC r.m.s. in overvoltage category II. Be aware that although this relay has a better endurance to inductive loads than the Yocto-PowerRelay-V2, 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-n and to a GSM network using a YoctoHub-GSM.
