Product Overview

RME2-AI-IA3 acquisition module is a complete interface for your analog sensors, because it
allows to monitor and supervise analog devices whose output is 4-20 mA current loops or 0-

10V voltage range. This device works in differential mode, which means that it measures the
difference between the absolute values of two signals.
