Wazaaaaaap guys!
I would to know if anyone use these relay (without a relayboard).
If uses it, which number of leads? I can't identify them by schematic.

24v relay?

Measure between pins with a DVM set to resistance. The pair which read something like 200 ohms are the coil.

Are there 4 or 5 pins in total? Or more? Difficult to see by the pic. You also need to know the DC current capability - it's likely lower at DC than the 10 amp at 125vAC.

Looks like 5 pin Dave...... SPDT I imagine????

I don't intend to be critical, but I am curious about why the OP would want to use electronic, pcb mount relays rather a more robust automotive type that is easily replaceable :?:

Maybe because they're sealed, so better for arduous conditions?

Here is a data sheet I found, that contains the pin-out for this relay.

Depending on what the OP intends, these may or may not be suitable for an automotive application.
