Post by thread:20 A PCB relay [OT]

I need to use eight 20 A PCB relay, to conect eight resistive lines (16 A app). I use a PIC to select them and wait about 15 minutes. My quetion is if a PCB can suport de 20 A or it depend on the with of the route.Exist a contector that can do that? Best Regards PD:sorry but english is not my native language Javier Puiggros spam_OUTvgrTakeThisOuTentelchile.net

You can buy PC mountable power relays which have 1/4" connect tabs on the top so that you can plug your high current stuff in directly and only the low current relay coil control goes through the board.

I've got a slide chart at my bench that says you need a .950 inch wide trace to handle 20 amps on a 1 ounce copper board, half that with two ounce copper. AMP makes several good terminals that will solder onto boards. I would recommend you rivet the connector on the board for these kinds of currents. I've got a project on the drawing board now using an AMP part number 61407-3 that can be soldered and riveted to a board.

You can get PCB relays with 6.35mm blade terminals on top, to connect the high-current directly
