'[PICLIST] [EE], Relay pins identify problem ?'

Hi,

I have a 12VDC relay but i can't identify its pins
the relay in a blue square shape

pins from top-view
-------------
|  o      o |
|           |
|         o |
|           |
|  o      o |
-------------
there is a writing in top " SONGLE"
and small circle at the top-right side .

What are the input and output pins ?

Thanks

Looks like a standard footprint.  But instead of telling you what I think
the pins are, how about I tell you how YOU can find out what the pins are?

You will need an ohmmeter of some sort.  Measure the resistance of 1 pin
(any pin) to all the others.  You will see one of three results:

1) no conduction to any other pin
2) a very low resistance to one pin
3) a resistance reading of several tens or hundreds of ohms.

Case 1) the pin is either not used (unlikely but possible) or is the
Normally Open contact of the relay.

Case 2) You have found both the Armature and Normally Closed pins on the relay.

Case 3) You have found the coil.

Do this until you have identified both the coil and contacts on the
relay.  Then apply power to the relay coil and look for a low resistance
reading between the pin identified in Case 1 and one of the pins identified
in Case 2.  The pin that showed low resistance both times (steps 1 & 2) is
the armature.  Done!

There is a Gotha in that there maybe a diode in the relay.
