The Signal Conditioning Wildcard is used with the Analog
I/O Wildcard to increase its input and output voltage range and to add 4-20 mA current
input and output capability This document describes the capabilities of the
Signal Conditioning Wildcard and tells how to connect and use it with an Analog
I/O Wildcard.
