When I converted my Anilam lathe to EMC2, I used the 5i20 + 7i33 + 7i37. If I understand correctly, the external boards convert the PWM signal from the 5i20 into a +/- 10V signal. I was thinking that the boards produced an analog output from a PWM signal, not an actual D-A converter. That's why I thought I needed PWM outputs, the drives themselves take +/- 10V. The output cards themselves output +/- 10V but I'm guessing the 5i25 doesn't output +/-10V, my guess it outputs 0-5V pwm. Sorry for the confusion, what I get from the output card isn't what I need from the interface cards, if it were I suspect I wouldn't need interface cards, just a breakout board.

I didn't see this combination listed on the documentation I have, mine's probably a bit dated.
