Connection drawing
We suggest you using a diode connectiong to the VCC in series. In order to prevent from damaging chip of Power Reverse or Voltage Fluctuation. ( The board does not add diode because the power would not enough to pull-in the relay for the buck from diode when power is too low. )
Package included
3 x Delay Timer Switch
