Subject: [Amps] SB220 SICK...RELAY
Thanks to all for your inputs. I am going to try cleaning the relay
contacts and watch alignment, etc.
If I can't get it going (contacts beyond repair), I would like to
replace the relay but a quick Google shows the KA-3702 relay by PB
doesn't exist.
My thinking is to grab the 120VDC present in the rig and regulate it
down to 5VDC or 12VDC (once I know the resistance of the coil) and then
get a 10 amp 3PDT relay. It will also make it easier to interface with
newer rigs that don't like 120V switched to ground through their
internal relays.
I could use a series resistor (with the R of the coil) to step it down
but I don't want to hot switch 120V (at T = 0) to any external relays
1) Anyone have the KA-3702 relay or a source?
2) Additional comments?
3) Relay recommendations?
Thanks
Jay
