4.0 out of 5 stars It's not a Toy !!!, April 18, 2012

Verified Purchase(What's this?)
This review is from: SainSmart 8-Channel Relay Module (Electronics)
Hey Kids, let's all play with 110v *sarcasm*
I ordered the part, as part of my tinkering with a Christmas light display that I'm teaching myself.
I ordered an Arduino Uno micro-controller and wanted to get this thing to work.

Anyway, this part came with no instructions.. nothing, nada. So I wrote the folks at Sainsmart a quick e-mail, the did get back to me, and since I can't find the schematic anywhere, I'll post it here

[...]
NOTE: These are obviously mechanical..so when I'm running through my light sequence, you'll hear "click click click"..
As I was working on the light sequence, it occurred to me that they could be used to control sprinkler valves as well..

Overall, I'm pretty impressed and their support does take days to get back, but they WILL get back :)

You should look into triacs, for resistive loads it shouldn't be a problem at all, smaller, cheaper (if you're willing to put together yourself), can probably switch faster and no clicking. Plus if I remember most triacs have a much bigger life cycle counts then relays..
