Thanks! Looks like I found it.

In case anyone needs it, here is the current link to the product:

And also attached the archive with documentation I found:

This board has one input for the encoder and two inputs for counters. The first input will definitely be occupied by the spindle. Do you think it is possible to use the counter input for the MPG? 

I thought so but not sure how that maps to A+ and B+

The encoder input of this card is in the form of a counter. There is no AB phase input. I have studied it before and gave up. Now I use the rv901 fpga card with six encoder inputs and more than a dozen input and output
 

Odd, it looks like the A+, A-, B+, B- and 5 volt power is provided for a motor encoder

However, it outputs the count value and has no direction. The encoder forward counter value increases, and the encoder reverse counter value also increases instead of decreasing.
