Arduino relay power supply question Hello everyone i got 2 ssr's from here



(link)

Sorry about the long link. My question is what power supply should i use. I was thinking a 12v 2amp. On a side note do i look at the input or the output when choosing a power supply

Thank you
In the product description it says "DC 12V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current." So 8 times 0.020A is 0.160A per board. I think your 2 amp power supply should work just fine.
