SCC-AI Series Isolated Analog 
Input Modules

The SCC-AI Series isolated analog input modules can extract a relatively 
low-amplitude input signal from a high-common-mode voltage so the 
E/M Series DAQ device can measure the input signal. They also can 
amplify and filter the input signal, resulting in higher measurement 
resolution and accuracy.

SCC-AI Series modules are available in a range of gains from 0.2 to 200. 
They contain lowpass filters of either 10 kHz or 4 Hz bandwidth. Table 1 
gives the gain and bandwidth for each module.
