Relays!?

Hi, I'm looking for short and simple explanation about relays;

  • how to identify them
  • how to connect them
  • how I know which one I should use for certain purpose

In my junk box I have a card with 3 relays on it. What can I do with these relays?

Thanks...again :wink:

You need 12V to trigger them, and they can then switch 10A at 250V

To identify what pins are for what, you can measure the resistance, if you find two that are not seperated, or connected directly together, it is probably the coil you found. When you got that, you can look at the remaining pins, and find the switching action there. :slight_smile:

What can I do with these relays

switch stuff

The part #s on the relays appear to be JW1FEN-DC12V and JS1aE-12V.

Try a google search for "Aromat", "datasheet", and the part numbers. That will probably turn up datasheets.
