Relay Board for the tinkerers........
I have been using horn relays for electric brakes, start,stop circuits etc. I found this board to replace the horn relays. Mounting and physical space is always an issue when building stuff. The relays can handle up to 10 amps, so they should work fine in many applications.
The board works off 12v. You can select the input that operates the relay to be either a ground or 12v.
I am finally cleaning up wiring in my R/C controlled transducer deploy/stow aka the Da Ducer Apparatus by Rickie the Great.
I consider this "occupational therapy".
