It's time for me to learn how these work and be able to test

Another reason I got them is because I suspect (probably erroneously :lmao: ) one side of my 30 volt dual power supply is only going up to about 13 volts :grr

I hope these are the same here is one from my power supply

:loco

Wondering now if they are real...idk xP

Ok looks like this is what the deal is

Check them with a multimeter.

Also measure activation coil DCR

Relays are interesting little devices.

They can switch a lot of power, up to 1500W here.

Browse online "old Electronics Books" libraries, I remember seeing 1 or 2 books dedicated to relay tricks and circuits, some very clever.

Yes sir thanks :tu:

Now I need to devise a plan to test the ones in circuit

Well I tested one of these new relays with a power supply and some leads and a multimeter monitoring continuity.

They seemed to open and close fair enough but I'll be damned if I heard a single click :grr

Idk maybe it's not supposed to make an audible click

But...I think that's what I am hearing click in the power supply as voltage is increased.

Comparing the markings on the devices I definitely see a difference but idk if that means anything.

Oh well it's not like I spent a fortune 🔮 on these.

It might be more obvious without adjusting supply while testing. Just set for 24VDC and turn on.
Some are not very loud, put your finger on it and you might feel the click.

Yes sir thanks definitely better doing it that way if I connect it at voltage I get a click

If I adjust the power supply "com" and "NC" open at about 16v DC then I have to roll it back to about 6v DC before it closes back up

Also if I hold the relay while doing that if I don't hear it I can feel it

Also I checked the coil like Mr Jaun said and it seems to match a data sheet I found

What's weird about the data sheet is I downloaded two pages and I can access and read them etc plain as day but if I try to upload them here they get dim and won't let me do it :grr
