Compact RIO Analogue I/O Module Selection

[David-Baratheon]

Hi everyone, sorry if this is the wrong place to post, I couldn't see any Analogue I/O section in the hardware section.

I am looking to acquire an analogue I/O module for a compact RIO, but there are quite a few options, and I wondered if there was any sort of guide to help me choose the most suitable module?

David,

This is going to mostly depend on what inputs you want to read but you should keep the following in mind.

How fast do I need to be able to acquire samples?

How accurate do these samples need to be?

How many channels do I need?

What voltage range do I need to read?

You can start at the following link and pick options on the left to get this down to a few modules.
