Hi kukarobot,

The following articles will help assist you as you look into which encoder to purchase:

KnowledgeBase 3JAF2BVB: What is the Difference Between a Line Driver, Open Collector, and Push-Pull ...
KnowledgeBase 2WO9LA59: Can I Connect Both PNP and NPN Signals to a National Instruments DAQ Board?

You will also want to be catious of the fact that counters on the USB-6216 will only accept signle ended measurements, so you will want to ensure that the encoder is not a differential encoder.

Thanks
