USER GUIDE
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.
