Hi I can see samples of breakout boards from Winford Engineering BRK2x25 and DaqStuff d-500013.
The advantage of MESA card is that MESA breakout board has one 50 pins
connector to let signals in (from 5i20) and 4 DB-25 connectors out.
So I used standard cable with mail female connectors DB-25 to connect my servo
amplifier (Servo Dynamic SD-94) to MESA breakout board.
So, I don't need to use screw connectors and then somehow connect them to servo
drive.
I believe that MESA breakout board more superior in design wise in compare to
competition.
Thank you,
Aramk

Yes, it should. You need a spindle encoder of course.

This is some info I gathered a while back.
* The Winford Engineering BRK2x25 is very nice, with 45 degree
angled terminal blocks that make it easy to wire to either row of
screws. They cost $45 each.

* The DaqStuff d-500013 has right angle terminals that make it more
difficult to wire the left row of pins, but only costs $25 each. (Note:
the "hard to wire" left hand row is the even numbered pins. If you are
connecting to the 5i20, those are the ground pins, and the signals are
on the odd numbered pins. If you are connecting to one of the 7iXX
interface boards, check its documentation to see what is odd and even.)

I haven't used either of the above boards yet, right now I'm using
something I got at a local surplus place (bought an electrical enclosure
for $25, got the breakout as part of the deal). Looks like this:
