The National Instruments PCI-4021 Switch Controller (Part Number: 778278-01) is a robust solution designed to manage advanced switching applications based on SCXI technology. This cost-effective model efficiently directs signals over various switching modules, facilitating the excitation of data acquisition measurement devices and allowing for seamless integration with third-party instruments within a PCI or PXI slot. The PCI-4021 is capable of controlling multiple switching modules, including the SCXI-1102/B/C, SCXI-1124, SCXI-116X family, SCXI-1190/1191, and SCXI-1127/1128. It is compatible with high-voltage backplane adapters such as SCXI-1357 and SCXI-1358, as well as low-voltage adapters like SCXI-1362.

This Switch Controller provides essential SCXI communication lines for effective module management within an SCXI chassis, making it particularly advantageous for production testing processes. The PCI-4021 comes equipped with an SH9MD-9MD cable and operates in conjunction with a computer running the NI-SWITCH driver software. The synergy of the SCXI chassis, module, and adapters enhances instrument functionality. Built with high-performance hardware, the NI PCI-4021 ensures sustained performance over time while delivering a low total cost of ownership throughout its operational life.
