Creating PWM Using Sinking Output on OB16IEF

[joelryan22]

The 1756-OB16IEF is a fast switching 12-24VDC output card. I'm doing a project where I need to control a stepper motor using 5V PWM signal.

I'm using a CL57T stepper controller. My plan is to apply +5V from a power supply to the Pulse+ and use the PWM sinking output to the Pulse- since the OB16IEF can't output 5V. Does anyone know if it's possible to use the PWM signal to sink a 5V signal to control the stepper motor or does the PWM function only work as a sourcing output?

I know controllogix is overkill for this project, but the point is to use industrial controls equipment so I'm sticking with it.

Thanks for any help!

According to documentation the card is sinking/sourcing so i would say yes, never tried it though as sinking.

Although, still, the specification is 10-30V for operation so no guarantee that the signal will pass through as should..
