What kind of relay board do you have, could you please post a schematic for the relay board?
You don't have to use the relay board posted here, as long as your relay board control input is limited to 10mA or so for each signal input.
You can have 5V relay board, as long as you provide 5V power to your relay board, do not take 5V from WebControl board, since it can not provide enough current for the relay board. If too much current, it could burn out the 5V regulator, then you will have to repair it.
