BEST BOB WE HAVE FOUND
This robust terminal box allows up to six digital devices to be easily connected to the I/O port of the Neptune Apex aquarium controller. Unlike similar input boxes from Neptune, ours features heavy duty spring terminals, with a separate common terminal for each input. This is very important, as a shared screw terminal becomes very unwieldy when you try to shove six wires into one small hole. With ours, just push each in by pressing on the tab, and releasing the tension to lock it in place.
