NI SCC-AI Series Isolated Analog Input

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 60 VDC per module.
