The X20SM1436-1 module from B&R can be used to operate stepper motors with operating voltages of 18-60 VDC at rated currents up to 2.5 A.

Rated for a 12- to 48-V dc input voltage, Haydon Kerk's DCM4826X stepper-motor drive module features a continuous output current rating of 2.6 A rms (3.68 A peak) per phase Rated for a 12- to 48-V ...

There is an additional stepper motor drive courtesy of a ULN2003 Darlington driver to allow the control of a single motorised axis.
