7i96S - NPN-NC Proximity Sensors and NPN-NO 3D Probe

Hey All,
I am in the midst of rewiring my PrintNC to use a Mesa 7i96S card to add some functionality that the BoB can't provide.

I have NPN-NC proximity sensors for homing and would like to integrate a NPN-NO 3d probe that I have lying around. I suspect this may be more trouble than purchasing a NC probe but thought I'd ask.

Is there any way to wire in the NO probe into the Mesa inputs? I've read about using a relay to convert the NO to NC but was wondering if I'm missing something easier. 

Would it be easier to run NPN-NO proximity sensors to match the probe? I'm open to making changes at this point and even have an extra set of NO sensors for homing but wanted to ask prior to making changes.

3d probe is here .
Proximity Sensors are here

Any help would be appreciated.
Thanks,
Rexus

The main NO/NC difference is just that you typically need to invert
the inputs of NC sensors in the setup, so no additional hardware is
needed.

You may be thinking of NPN vs PNP.

The 7I96S only has one input common terminal so cannot
accommodate a mix of NPN and PNP sensors without adding
external resistors.
