A relay is an electronic switching device that controls current. It can be controlled with low voltages, like the 5V provided by Arduino pins. Solid state relays have no mechanical parts to wear out, so they should last longer than electromechanical relays. Specifications power supply: 5 VDC power current: max. 10 mA input voltage: relay ON: 0 to 2.5 VDC relay OFF: 3.3 to 5 VDC max. load: 240 VAC 2 A 50/60 Hz dimensions: 2.5 x 2.5 x 3.6 cm weight: 6 g protection: 2A Pico fuse on board User manual Show more
