I purchased a 24v NPN 4 relay board for my lathe and didn't receive any schematic with it. I messaged the seller & received this response:
"We don't have the manual for this item now, but it is easy to use. This is a NPN type, all relays are Common Anode. Please connect 24VDC positive to the COM+ terminal and negative to -1.-2.-3 or -4."
I Googled the number on the board & came up with nothing. Anybody familiar with how to connect these? It looks to be well made & the price was great but I don't want to risk smoking my Acorn.

Re: Relay board connections help
Just because I like you Milton, I got up early and made a video...give me a few minutes and it will become a quick tip.

Re: Relay board connections help
That's an awesome video, thanks Marty! Very easy to understand your explanation. When electronics people start talking about anodes, cathodes, NPN, PNP, and all those kinds of terms, I just don't get it.
