switching
(OP)
hello,
i have plasma cnc with torch height controller. the controller outputs dc +- to move the torch up and down.dc
gearmotor, 24v. trying to interface to stepper motor drive.
need the + or - dc approx. 1-2 volts to switch 5v tll for the stepper software to sense direction for up or down.

RE: switching
i would need a relay or switching circuit so that 1v pos from the torch controller will close switch for the stepper 5v tll to move up. !v neg to close switch to move stepper down.
transistor to trigger separate relays for the 5v tll?

would the reverse 1v be a problem for this?
