Triconex Trident and TriGP Question

I am quoting a job and my source at Triconex is no longer employed there and I'm out of the country right now so resources are limited. My source told me one time that if you are using Trident or TriGP that you are limited to only 20 analong output channels in your system.

Can anybody confirm? I need about 32 channels counting spares, I probably need to stick with Tricon.

With Trident or Tri-GP, you are indeed limited to 20 AO points per controller; 5 AO cards with 4 outputs each.

Thank you for the reply. I wonder why they limit you to so few.
