Old DIL relay pinout help request

Have you actually tried "logging on" to RS? They offer an alternative

Hi Matt, Thanks for the reply - I tried searching for the relay with this part no (discontinued) and also the "equivalent" but the pinout given does not correlate with what I have - on three relays in case they were "faulty". Hence the request for specific data on this relay - I will look at the suggested website though, Thanks, Nick

I would have thought it would be quicker to test them with a multimeter and a supply that will run the coil.

That "website" is just the image data from RS.

Just how long would it take to ring them out with a continuity device? ;-)

Dave Plowman (News) was thinking very hard :

That would find the coil winding 100-150Ohms and the nc contacts, but the coil usually has an internal diode across it to kill the back EMF. How he can work out the polarity of the diode with the coil in parallel and hence the +/- connections?

remarkably easily. Apply some kind of supply via a current limit R, eg a bulb. Apply both ways round.

OP could do this as quick as typing the original post, and quicker than hunting thru a website.

With an ohm meter. Diodes are a near short to DC in one direction, open circuit the other.
