High Current DCC Controller

We’ve been asked by a number of customers if it is possible to use the DCC system to control 4QD units. This page shows the outline of a way this can be done to create a really high current DCC controller. High current dcc controller

The value of the zener diode will depend on the model of controller being used as follows;

Component 4QD series DNO Pro-150
Zener voltage 9v1 9v1 4v7

The values of R1 and R2 depend on the output voltage of the DCC receiver as follows;

DCC voltage
Component 12v 24v
R1 1k 1k
R2 1k 2k
