Use this relay to control power hungry devices via microcontroller such as Arduino or Raspberry Pi. When you apply 3V to 32V across the 2 input terminals, the output terminals become connected internally. This is a solid state relay which gives your faster speed and a longer life than standard mechanical relays. Useful for home appliance control.
