It's allowed by code:

300.3(C) Conductors of Different Systems.
(1) 600 Volts, Nominal, or Less. Conductors of circuits rated 600 volts, 
nominal, or less, ac circuits, and dc circuits shall be permitted to 
occupy the same equipment wiring enclosure, cable, or raceway. All 
conductors shall have an insulation rating equal to at least the maximum 
circuit voltage applied to any conductor within the enclosure, cable, or 
raceway.

Exception: For solar photovoltaic systems in accordance with 690.4(B).

FPN: See 725.55(A) for Class 2 and Class 3 circuit conductors.
