National Instruments PXI-2535

The National Instruments PXI-2535 (Part Number: 778572-35) is an advanced PXI Matrix Switch Module featuring a high density of 544 crosspoints configured in a 1-Wire matrix design. This module is particularly suited for routing DC signals in applications such as validation testing of mass-manufactured devices, including printed circuit boards (PCBs) and semiconductor chips. The PXI-2535 uses field-effect transistor (FET) relays, which provide exceptional speed with the capability to achieve up to 50,000 crosspoints per second while ensuring unlimited mechanical lifetime.

Engineered for optimal performance, the module supports relay monitoring and deterministic operations through onboard relay counting provisions in conjunction with hardware triggers, significantly enhancing test throughput. The switching capabilities include a maximum voltage of ±12 VDC and 8 VAC (channel-to-ground), a maximum switching power of 1.2 W per channel, and a maximum current capacity of 100 mA. With a typical DC isolation resistance exceeding 1 GΩ at 23 °C, the PXI-2535 ensures robust performance, while integrated overvoltage protection is triggered at ±36 VDC in powered-on state and ±40 VDC when powered off.

This matrix switch module provides a single crosspoint bandwidth of greater than 1 MHz for a one row to one column, 50 Ω configuration. The operating characteristics include a typical relay switching time of 12 µs and a maximum of 16 µs, alongside the capability to simultaneously drive up to 544 switches. Designed as a compact 3U PXI module, it occupies a single slot and includes four 68-pin receptacle VHDCI I/O connectors. The PXI-2535 operates within a temperature range of 0 °C to 55 °C, with a power consumption of 1.7 Watts at 3.3 V and 1.3 Watts at 12 V. The module dimensions are 8.5 x 0.8 x 5.1 inches, and it weighs 5.6 ounces. A standard warranty of 2-3 years is included, and user and maintenance manuals are available for download.
