Actually, it can drive 4 relays from intervalometer independently

But, you still need to do some additional wiring on that board (soldering.. and adding a resistor or two).
If you are comfortable with this, or if you can find someone to help you, I will post the schematic later - it involves adding one resistor, adding one short wire and cutting one track on that board.

Thank you again Bojan.
If you feel like posting a schematic then I can at least take a look and decide. But I am not electrical clever.
If the schematic is basic enough I might be able to work through it with some help.
Can't hurt anyway.
