Can nema motors be wired directly to this unit or need seperate drivers?

Needs to have separate drivers.

cant get limits or home working. I have one 24 volt connecting. Is this correct or do I run lines from power supply to input board?

The Power Supply for the controller is 24VDC, and this DDCSV3.1 needs TWO power supplies,main power is for system,IO port is for input and output ports, Current is not less than 1A;Because of the IO power,system can supply the power for all IO ports.So no need the external power supply for IO port anymore;

What two power supply dcv and amps are recomended?

24V DC,and the current is not less than 1A.
