Thanks for the prompt reply, @ryan1. Would you be able to share a PDF with schematics of the PR16-12 board? I think that make it a bit easier to debug while Travis is out.
Hi Alan,
We do not have a PDF with this information, but it’s very simple. The GPIO lines should be set to output to control the relays, this is the first step. Next, the GPIO lines can be turned on or off, the GPIO lines will directly control the relays. Hope this helps.
