You need stationary decoders to run turnouts. Several different manufacturers make them. Since they are on the "track side" of a DCC system, they should all be compatable with your DCC system.
Each of these stationary decoders should come with wiring diagrams. Then you can control your turnouts from your DCC throttle unit.
You may find, however, that this is an expensive and overly complicated way to run turnouts. I personally prefer a control panel on the side of the layout, with "traditional" toggle switches to control turnouts, mounted on a schematic track plan so that I can tell where each turnout is. I still run my trains from a hand-held DCC throttle, but for me it's just easier to flip a toggle switch than to remember the address of every turnout, punch it in to the throttle, activate the turnout, and then go through another key sequence to regain control of the train. But, that's my choice, and it works well with my layout. Yours may be different, and as we always like to say, it's your railroad.
