What
would you suggest as a circuit to control 5v input from the port to 56vdc
output? I have tried relays but they are too slow to get the stepper to the
speed I need. Would I be correct to say I need to use (is the word) descrete
components?
You need a transistor. A discrete component is just a "not inside an IC chip" thing.
An example setup with a NPN transistor:
+5V to base (resistor may be required)
+56VDC to motor to collector
Common GND to emitter
Someone else might suggest a part number.
