National Instruments PXI-4021

The National Instruments PXI-4021 (Part Number: 778277-01) is a high-performance PXI switch controller designed for controlling SCXI-based switching frameworks. It operates seamlessly from a PCI or PXI slot without requiring additional programming, leveraging the NI-SWITCH driver included with National Instruments switches. For users seeking a plug-and-play solution outside the constraints of PCI or PXI slots, the USB-1359 communication adapter offers USB control of an SCXI switching chassis. Each PXI and SCXI switch module is equipped with the NI-SWITCH driver, ensuring comprehensive functionality and IVI compliance.

The PXI-4021 enhances automated test applications by facilitating higher throughput through scanning capabilities. It allows up to 32,000 connections to be downloaded and cycled through via event triggers, minimizing interference from the host processor. The controller supports flexible configurations, enabling users to manipulate relay environments and consolidate banks of 16x1 multiplexers to achieve various multiplexer sizes or operate independently for customized applications. Additionally, integrated terminal blocks provide options for screw terminals, spring terminals, or ribbon cable connections, simplifying integration with multiple modules and facilitating high-channel-count system setups. The PXI-4021 is covered by a 2-3 year warranty, with user and maintenance manuals available for download. For pricing inquiries, please contact a National Instruments sales representative.
