In further research of my relay options, I came across these relay boards available in 2, 4, 8, 16 relay's.
Since I use a converted ATX power supply for my projects 12V requirements, It seems I have a spare 36 Amps on the 5V rail 
With the above relay board, do I remove the jumper between JD-VCC ^ VCC on the three pin header and connect my atx supply to the VCC & GND pins on the 3 Pin header?
Then Connect the 4-pin header GND to arduino GND and IN1, IN2 TO D5, D6 and leave the VCC Pin empty?
The current older boards I have use 12V coils on relay and only have TTL pins for the connection, ie GND + 8 TTL, The 12V is on screw terminals.
