NI PXIe-6363 PXI Multifunction I/O Module

The NI PXIe-6363 is a high-performance PXI Multifunction I/O Module for data acquisition and control applications requiring precision timing, synchronization, and multichannel signal processing. It integrates 32 single-ended (or 16 differential) analog inputs, 4 analog outputs, and 48 digital I/O channels with onboard NI-STC3 timing technology. The module exploits the high-throughput PCI Express bus and multicore-optimized drivers to deliver efficient, synchronized data handling across demanding measurement and automation systems.
