Raspberry Pi 16 Channel Relay not working correctly

[engine-ad-oz]

Hi Pete,

I followed your youtube video and downloaded the python scripts. I've wired the relay board and raspberry Pi as per your video. The problem I'm having is I can't cycle the relays as your video does. They come on together and switch off together.

I'm sure the code is doing the correct thing and I'm confident the wiring is ok. Are there any subtleties with the relay boards? I got this one off ebay, there are no jumpers to set or anything, just connect 12v and the pi and I think it should work.

Anyway cool videos and very well presented.

Hope to hear from you soon.

Cheers

can you upload a pic of it? I worry its not an optocoupler relay...

Hope that comes through.

[skiwithpete]

Yep, that's what an optocoupler relay looks like, so that's not the issue... Umm... When you plug in just two relays. You can't get them to fire individually?

what I'm asking is: even if you only plug two in? Do they all come on? On Wed, Apr 29, 2020 at 9:05 AM engine-ad-oz <notifications@github.com> wrote:

Sorry misunderstood, only the ones that are connected. So in that example only 2 would come on but with no independent control. Get Outlook for Android<https://aka.ms/ghei36>

This is so highly unusual. I mean, I've had this script up for years, and been dealing with issues across that time, and I haven't heard of this before. Two possibilities 1) incorrect wiring. 2) defective unit. Let's look at 1, before we jump to 2. There are ways to power the 16 channel relay with just two switches that relies on 5V rather than the full 12V. Have you tried that? Or, did you make any modifications to the code? IE the pin numbers? That's pretty much it... like I've gone through all the things that typically go wrong with these things, and If that still doesn't work, I've got to think you've got a defective switch board. One that's leaking across the line. So that powering one does multiples... but even then, that typically when you only power 2 switches, it would still light up all 16. So I'm really stumped here. Maybe one last last last thing. You've powered up 2 switches, I assume you chose 1&2 can you try 2&3 or 3&4? And for good measure - now that we've taken pics. Can you take a pic of your wiring for your 2 test switches as above? On Thu, Apr 30, 2020 at 4:14 AM engine-ad-oz <notifications@github.com> wrote:

I'm guessing its a faulty board, the pi works fine for everything else I play around with and the only code changes I made were to rem out lines that werent required as I cut down the number of relays I was trying. I'll take some pics of the wiring when I het a chance, ive got another relay board coming and another pi to try too. Thanks for you help. Get Outlook for Android<https://aka.ms/ghei36>
