Default Relay V23012 spec?

I am trying to find a suitable equivalent to this Siemens relay, type number: v23012 a2102 a004.

The circuit in which it would be used suggests the coil input voltage is 15v. So presumably this would fall within the tolerance of a 12v component, as a 24v would probably not be triggered. For this reason I'd like to ascertain the exact spec of the original! Google produces lots of results but seemingly not of this exact type.

TIA,

There's a V23012-A2102-B001 for sale on Belgian distributor site:-

https://vikiwat.com/product/22853/el...no-2nc.en.html

That page shows condensed specs for the B001, and a data sheet for another V23012 series shows that the final four characters of the part number just specify the type of contacts:-

https://www.datasheetarchive.com/pdf...=M&term=V23012 (In German.)

B001 = 'silver, gold-plated; Double contacts' (- presumably meaning bifurcated.)

-whereas:
A001 = 'silver, gold-plated; Single contacts'

(Both are '2 changeover contacts'.)

Cheers

This is in German, but you should be able to decipher the info you need - specifically, the 12v version will work between 8.3 and 22V.

Thanks to you both for the information. Seems to suggest what I have is indeed 12v.

What I hope to do is replace it with a modern substitute. The Siemens ones on sale seem as old as the 40-year-old ones I have now, and given the fact they aren't sealed, I suspect the contacts will be equally tarnished. Given the PCB has extremely fragile traces, I want maximum reliability so I won't have to touch it again anytime soon!

I have a NAIS JW2HN 12V which seems to fit the bill. I might have to get creative in mounting it. Data attached.
