Pack of 3 autofrogThe DCC80 Autofrog is a simple switch that automatically changes the frog polarity on your DCC layout.DCC Track Voltage: 12-20vFrog Current: 2 Amp maxDCC80 Typical Current Consumption: 20mAIn most situations, the use of electrofrog points is recommended on digital layouts to ensure reliability but this can make extra switching more complicated than it needs to be. Allow us to introduce you to the Autofrog. Wiring the DCC80 is simple. There are three solder connections on the board, 2 connections labelled “R” - which you should connect to your rails or your bus and 1 connection labelled “F” which you connect to the frog input wire.As there are so many variations of point/turnout, we recommend you follow your track manufacturer’s instructions.
