The Yocto-PowerRelay-V2 is a small USB power relay. It contains a USB-driven SPDT power 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 currently active output.
This device only includes a single relay, but it can drive higher loads than the Yocto-Relay. The relay and the connector can stand a current of 5A. When put into an enclosure, the Yocto-PowerRelay-V2 can be used to directly switch hazardous live mains circuits up to 150 V r.m.s., and even up to 250 V AC r.m.s. for secondary circuits. Note that the Yocto-PowerRelay-V3 is more appropriate to switch loads 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.
USB cables and enclosures to be ordered separately.
