The PCI-4021 (part number: 778278-01) is a high-quality switch controller from National Instruments. This model implements an advanced switching system, which is based on SCXI technology and does not need any other software. This switch controller is less expensive than other models and provides suitable control elucidation for switching modules. It is used to direct signals over a switch, to excite the data acquisition measurement devices, and for switching modules with third-party instruments from a PCI or PXI slot. This model can easily control many switching modules, which include the following: the SCXI-1102/B/C, the SCXI-1124, the SCXI-116X family, the SCXI-1190/1191, and the SCXI-1127/1128. These controllers are attuned with high-voltage backplane adapters like the SCXI-1357/1358. These controllers are also compatible with the low-voltage adapters like the SCXI-1362.
The National Instruments PCI-4021 provides all the vital SCXI communication lines. The user can control the modules with the help of these lines. These modules are integrated inside an SCXI chassis. This switch controller is particularly valuable in production tests. Furthermore, the PCI 4021 has an SH9MD-9MD cable. Besides this, it requires a computer and NI-SWITCH driver software to operate. The SCXI chassis and module, along with an adapter, can operate in combination. This enables the user to functionalize the instrument.
The NI PCI-4021 Switch Controller comes with high-performance hardware, which helps users with sustaining the performance for years. With the versatile capabilities of this model, National Instruments ensures a low total cost of ownership throughout the system’s life.
