The National Instruments PXI-2522 is a General-Purpose Switch Module designed for integration within the PXI platform, leveraging its inherent timing and synchronization capabilities to facilitate communication with a variety of instruments. This module features 53 independent Single-Pole Double-Throw (SPDT) relays, capable of handling up to 2 A of switching and carrying, with a maximum voltage of 100 V. The PXI-2522 allows users to store switch associations directly on the module, enabling quick relay sequencing that minimizes software overhead and reduces bus latency, resulting in a more efficient testing process with improved repeatability.

For enhanced operation, the PXI-2522 is equipped with an intelligent front panel, providing a graphical user interface for real-time control and monitoring of switch states. Users can track dynamic signal paths and the status of individual relays, as well as monitor relay usage throughout testing sessions. The module supports a 145 cycles per second switching frequency across a bandwidth of 51 MHz, ensuring rapid and reliable performance.

Designed for indoor environments, the module operates within a temperature range of 0 °C to 55 °C and can be stored at temperatures from -20 °C to 70 °C. It requires a power supply of 7 W at 5 V and 2.5 W at 3.3 V. The PXI-2522 connects via a PXI Hybrid bus connector and includes a DIN 41612 male I/O connector for flexibility in system configurations. With dimensions of 8.5 x 0.8 x 5.1 inches (21.6 x 2.0 x 13.0 cm) and a weight of 6.77 oz (192 g), the PXI-2522 is a robust and efficient solution for automated testing and measurement applications. The product includes a 2-3 year warranty and comprehensive user manuals for installation and maintenance are available for download.
