Overview

OverviewOverview

RMS2-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 0­10V voltage range. This device works in differential mode, which means that it measures the
difference between the absolute values of two signals.

3333 Configuration

RMS2-AI-IA3 configuration is done through a command console connecting the device to a
USB port on the PC.

To access the command console, you must connect the RMS2-AI-IA3 to a USB port on a PC
and you must install an Exemys serial terminal program, named

Download the USB driver:

Example:

RME2-AI-IA3 can convert the measured value to a scaled value.
For example, you can convert a signal from a temperature transducer with
4-20mA output to a reading of -100 to 500 degrees Celsius; for this, you must set the
2 points to scale, in this way, device applies the equation of a line given that you
know two points it passes through.

Next, we will post an example about it was explained previously:

It’s necessary to convert a signal from a temperature transducer with 4-20mA output to a
reading of -100 to 500 degrees Celsius. For this, the output values would be
YMIN = -100 and YMAX= 500.
