Hello,

I’m quite sure I will not be using C track but………..

Does anyone know what the capacity is for using the 74462 digital decoder C track on a larger layout?

I realize that there will be a power drain on the power supply but what is a reasonable amount before you use the K83’s?


Regards

The decoder is for turnouts Using my CS3 I dont see how there is a limit to the number on the layout. They change one at a time so dont see how there is a drain on the power supply.
I maybe dont understand the question.


Take care I like Marklin and will defend the worlds greatest model rail manufacturer.

Just wondering can you use sixty without an issue?

Yes, but more expensive!

The power consumption of a single inactive decoder should be 0.02 A or less.
The CS3 has 3 or 5 A output.
With 100 decoders you will probably be somewhere between 1 A and 2 A and there is still power left.
And if you have a track plan with 100 turnouts, you should prepare the layout for booster sections anyway.

Thanks David & HO,

I have decided to renew my layout, possibly using K track and this decoder. The main reason being is by eliminating the wires under the layout.

I am not sure as I dont have K track but the decoder and motor are made to clip in to C track. Somebody with K track could maybe help and confirm no wiring is needed.

Dave, you are right, these decoders aren't designed for K track. They plug directly into the C-track switch motors. To hook the to K track the plug connectors for power and motor will have to be clipped off. I think it is easier to use the K/M83 solution.

Roger

Doesn't K track accept most any type/brand of solenoid actuator? Then you can use either Marklin M-84, or Viessman decoders.

Where would you put them. I suppose you could wire them under the baseboard but 70 of them would not be great in my view.
