Reply With QuoteTrigger pins are electrically insulated from NO, COM, NC. You also need to provide power source to the bulb
EDIT: what type of relay is it? Any model number?
Although the pettiness of my problem can't be confidence inspiring, I really do know how a relay works. Now it's certainly possible I am not connecting to the right connectors, but I don't think so. If you want to look at a reference that is a little more relevant to this problem (given the relay marking I have) please look at this and let me know what you think.

The relays I have are triggered by 2 wires soldered to the bottom - hard to screw that up if I do say so myself. I started off triggering this with a FB but have also applied 12v (and ground) to them directly with no better results. These are not shown in my diagrams.
For the rest of it, the page above matches it pretty well. I have 3 connectors, COM, NO, NC, which I expect to work as described.
2k1Toaster, do you see any problem with the way I am testing or have these wired up?
thanks,
charles

If you wire it 12v -- com -- no -- bulb -- ground and then power the relayOriginally Posted by cgalpin
coil from the 12v direct (no arduino at all) and the bulb doesn't come on...
then quite simply the relay is goosed!
Or it's some mad relay that needs huge voltage across it's coil.....

Yes which is why I showed you
12v -- bulb -- ground
This works fine. All I did was add the relay to the circuit. It still has ground.
Yes this is why I am stumped. This should work! But 4 relays act the same way. I guess I'll try the last 2 to be sure
It's the ones the FB folks sell.

This one needs 24V DC for coil, you are supplying 12V.
wtf! must be that pesky -24 on the model number!
Dayum. well, that would explain it. Sure will suck if I ordered the wrong ones
Thanks man!

2k1Toasterer I sent ya'll an email as your site doesn't offer choices so the mistake must be on your end. This is what I bought

The relay on a pic has a 12V coil, you got different ones, 24V model.
Yeah I'm kicking myself for not realizing that because I did google it as soon as the first try failed and I should have noticed
