NI SCC-AI04 2-Channel Isolated Analog Input Module

The NI SCC-AI04 is a 2-channel isolated analog input module that delivers high-accuracy voltage measurements in electrically noisy environments. It integrates signal conditioning, filtering, and 300 V working isolation to extract low-amplitude signals from high-common-mode voltages. The module amplifies input signals with a gain of 2 and applies a 3-pole lowpass filter at 10 kHz bandwidth to improve measurement resolution and accuracy.
