There is none, your free to mix voltages.
There are restrictions on mixing certain systems or classes together.

All the conductors must be insulated for the highest voltage.

And only for conductors of electric power, light and similar. Not for "low voltage" , what ever that is.

The article on "low voltage lighting" is Article 411 Lighting Systems operating at 30 votls or less, not "low voltagedlhoule said:
Low voltage and power and lighting are not permitted in any all cases even with the same insulation rating.
This important point is missed by most electricans.
Read 90.3
Read 300.3 (C)(1)
Follow the FPN
What you call low voltage is really a class 2 circuit per article 725. Also note the title to article 725, its not low voltage.

Thanks for pointing out these differences. Actually it would have been clearer if I had said what I was thinking. If it is 600 V or less and the wires are all insulated for 600 V and are of the same class, they can be in the same raceway. What I call low voltage is anything under 50V. Now if we are referring to RVs, I drop that down to 24V. 720.2 lists several other articles that shall not be required to comply with article 720.
I am out of time. Would you define remote control for me? A light switch controlling an outside light could be considered remote control.
