RevPi Analog-IO Module

Expensive 4-20mA transmitter, but at least it would have worked in principle

Expensive and sizable option to get a single 4-20mA transmitter. I ended up returning it without testing.

Good Module Works as Expected

This module works as expected. Only wish the RTD ports were configurable to also be just Analog. I need more than 4 inputs on most projects and this module is not cheap.
