National Instruments PXI-2529

The National Instruments PXI-2529 is a high-density, 1-Wire, 128-Crosspoint PXI Matrix Switch Module, featuring a versatile configuration capability that allows users to set up the module as either an 8x16 2-wire matrix or a 4x32 dual matrix, with various NI terminal block accessories. Built with latching electromechanical relays, this module provides exceptional performance for low thermal offset and can handle high-power signals, ensuring precise low-voltage measurements. The PXI-2529 includes relay counting for deterministic operation and relay monitoring with hardware triggers, thereby enhancing test throughput. The module uses a 100-pin high-density interconnect front panel connector and maintains a Measurement Category I rating, suitable for signal voltages under 150 volts with a maximum withstand for voltage surges up to 800 volts.

In terms of electrical specifications, it supports a maximum switching power of 30 W and a maximum switching current of 1 A, with a maximum carry current of 2 A per channel and up to 8 A total. The device offers a robust channel-to-channel and channel-to-ground switching voltage of 150 V, along with a release time of 4 ms maximum at 20 °C. The mechanical relay life is rated at 5 x 10^7 cycles, while the electrical relay life reaches 5 x 10^5 cycles at 30 V and 100 mA, and 1 x 10^5 cycles at 30 V and 1 A. Physically, the PXI-2529 measures 21.6 x 2.0 x 13.0 cm and weighs approximately 410 g (15 oz). It is designed as a one-slot, 3U PXI module compatible with PXIe chassis, consuming 65 W at 5 V and 2.5 W at 3.3 V when operating in PXI configuration, and 7.5 W at 12 V in PXI Express mode. The recommended operating temperature range is between 0 °C and 55 °C, with a storage temperature range of -20 °C to 70 °C. The PXI-2529 is backed by a three-year warranty, and documentation, including user and maintenance manuals, is available for download. For pricing inquiries, please contact a sales representative.
