Some follow-up questions:
1. We don't currently have a very good solution for 32 channels of AO at 30V. Would external amplification be an option here?
2. Do all 32 of the digital lines need to be both input and output? Do they need to be hardware-timed? Do they need to be sourcing or sinking?
I'm currently leaning toward the compact DAQ platform with the following modules:
AI: 4x 9221
AO: 2x 9264 (could replace one with a 9263 and still have 20 channels if specs are acceptable). Would need external amplification. These modules are also bank isolated so you give an external COM reference if desired.
DIO: Some options here depending on what you need. Assuming you just need static updates (i.e. software-timed).
-9425/9426 for input (depending on sinking or sourcing current requirements)
-9476/9477 for output (depending on sinking or sourcing current requirements)
Hardware-timed Digital modules in cDAQ are limited to 8 channels per module (see 9421, 9422, 9472, 9474 for 24V logic variants).
