NI SCXI-1162HV 32-Channel Isolated Digital Input Module

The NI SCXI-1162HV is a 32-channel optically isolated digital input module for SCXI chassis-based data acquisition systems. It safely measures digital signals in high common-mode voltage and ground-loop environments by providing individual optical isolation on each channel. The module protects DAQ systems and connected equipment from voltage spikes and surges while accepting digital logic levels up to 240 VAC/VDC across diverse industrial and laboratory applications.
