18D KTU to provide A Lead control #642071 01/30/22 10:37 AM

I need 2 for my home application (I have one already). These hardly ever come up on eBay; I see relays out there now, the... 2A 5A 6B 17B Can any of these be used (I didn't locate info in any BSPs on these)? I only need the function to show line in use, not removing from hold if this makes a difference. Thanks for any guidance! Jim

They gave an off=hook indication, but as I recall they wouldn't break hold. Sandman used to sell A- Lead control stuff as did...Crest? Maybe. The 2A was as i recall for T&R for an ICM (I could be very wrong - it's been a l o o o n g time. The 17B was a DPDT relay. I'll email you PDFs of the relays that I have.

He had board designs and such I think, and they're /probably/ easy to build. Not sure though..

Luckily, there are 6Bs on ebay, and I just ordered them. Can't wait to test and compare their operation to the 18D I have on another line. Since I'm only looking for the line-in-use indicated via A-Lead, the 6B may be the ticket! I'll post my results. Thanks for helping. Jim
