Just needs 2 wires for GND + 3.3V and 8 wires for the 8 relays. You can use the newer arduinos that are in 3.3 V logic or a Raspberry Pi GPIO (also in 3.3 V logic) or any of the older Arduino (Uno, Mega) which are 5V.\u003cbr\u003eThe outputs relays are silent -- search \"OMCRON G3MB-202P\" for the datasheet.\u003cbr\u003e\u003cbr\u003eThese are zero-crossing PhotoTRIACs with snubber circuits. Their load rating is up to 2 A at 100-250 VAC.\u003cbr\u003eWorks fine with low-voltage 16 VAC too, for example model train accessories power supply.\u003cbr\u003e\u003cbr\u003e[Edit] To clarify one thing: the solid state relays use triacs (TRIAC=triode for alternating current) which means the relays will only close when using an AC load. You cannot drive a DC load with these.
