3 Amps Diode

This 3 Amps diode can be used in line with outputs to prevent back feed to the receivers and controllers. Connect your output to one side of the diode, and the other side of the diode connects to the valve or output that is shared with an override switch. It is also used for diode logic and coil noise suppression.  Solder both sides, and cover in heat shrink, electrical tape, or otherwise protect as necessary for your application.
