National Instruments SCC-AI Series modules are dual-channel bank-
isolated analog input modules for reading input voltages from ±50 mV to
±42 V. Each channel of an NI SCC-AI module includes an instrumentation
amplifier, a lowpass filter, and a potentiometer for calibration. These
modules are installation rated for CAT I, and provide safety working
isolation of ±0 VDC per module.
