As many of you know, I am a fan of the OMRON relays for the V11. I found Ryland3210's evaluation compelling and have seen numerous (other) relay failures on V11 over the years.
Yet, I'm afraid I keep posting a Digikey link for an part no longer available through them.
I struggle with deciphering this part number:
G8HN-1C2T-R DC12
--->EDIT (Mar 28 2018): Best (High Current) Relay, derived from this thread: Link to this post on page 5: http://www.v11lemans.com/forums/index.ph
I ran across one of Kiwi_Roy's earlier posts (http://www.v11lemans.com/forums/index.php?showtopic=12326&p=201362), where he measured various loads in these circuits and Relay#5 is carrying 22.5 amps. No wonder Relays rated for 20 amps suffer there (and get hot). I have temperature readings on mine, so it may be an indicator if this higher rated OMRON runs cooler.
Thanks, Kiwi_Roy!
