In this video, How to make an 8 Channel relay driver board, I've explained how to make an optically isolated relay driver circuit by using an optocoupler, here I've used PC 817. This will isolate between input and output section for safety purpose. This type of board is widely used with microcontroller circuit or digital ic circuit to drive high voltage devices. Input of this board is active LOW. Active LOW input is always better than having an active HIGH input.
