Overview

The NI PXIe-6381 is a multifunction PXI Express I/O module providing 16 analog inputs, 2 analog outputs and 24 digital I/O lines. With +/-10 V range, 18-bit resolution and 625 kS/s aggregate sampling, it is positioned as cost-effective, high-precision data acquisition within NI's PXI platform.

It carries NI's software-defined measurement model — configured through InstrumentStudio and automated with LabVIEW, TestStand or text-based languages such as Python and C/C++ — and synchronises with other PXI modules over the chassis backplane.

Key Benefits

Combines AI, AO and DIO in a single slot; 18-bit precision at 625 kS/s; PXI backplane synchronization for mixed-measurement systems; accessible price point for scalable test.

Applications

Automated data acquisition, sensor and signal monitoring, mixed-signal validation, control-loop testing, and AI-enhanced measurement analysis.
