How to wire a turntable for dcc

How do I wire the track of a turntable?

I have always used a ring of metal around the center pivot and 2 wipers that come down from the bridge and rub on the ring, 1 wiper for each rail. The ring is divided in half so polarity is always correct to the track.

You can do the same thing with the ring rail. Just divide the ring rail into 2 different circuits.

Another option is to power the ring rail and power the center pivit. Then you connect each rail on the bridge to one of these sources. The only problem with this approach is that you will need a polarity reversing switch, automatic or manual.

I gather you are using DCC? If you are, just purchase one of the many autoreversers that are out ther and hook up according to the instructions. You then don't have to worry about reversing the polarity using a toggle switch.

Tonys Train Exchange has a comparison here: Autoreversers

 

Yes, I am using DCC. I have an ARSC from loystoys. Will that work?
Thanks,

Looking at the Loys Toys site, the ARSC can't be used to control a turntable. I did see that Loy has the D-ARI which would be perfect for what you need to do.

Hope this helps.

 

David:

You can use any reverse loop module/switch.

Stay cool and run steam....
