{"product_id":"national-instruments-778572-33","title":"National Instruments 778572-33","description":"The National Instruments 778572-33 PXI Matrix Switch Module, also known as the PXI-2533, is engineered for high-channel-count automated test systems, featuring a 1-Wire 4x64 configuration. This module is built with solid-state relays (SSRs) that provide an unlimited mechanical lifetime and enable simultaneous routing of up to 55 W across all channels. The SSRs exhibit rapid switching capabilities, boasting an operate time of just 724 µs and supporting a maximum scan rate of 400 crosspoints per second. It has impressive specifications, accommodating a maximum switching voltage of ±55 VDC or 30 VACrms, with a current capacity of 1 A and a maximum switching power of 55 W. The module's DC isolation resistance exceeds 2 GΩ, ensuring minimal signal interference with a low offset voltage of 2 µV. The total path resistance from row to column is maintained at 1 Ω while delivering RF performance with a typical single crosspoint bandwidth of over 1.5 MHz in a 50 Ω system, alongside crosstalk levels below -40 dB at 10 kHz and less than -20 dB at 100 kHz, all of which contribute to high signal integrity for precision testing applications. Its triggering functionality includes input triggers on PXI trigger lines \u0026lt;0…7\u0026gt; with a minimum pulse width of 70 ns and software-selectable output triggers ranging from 1 µs to 62 µs. The module occupies a single slot in a 3U PXI\/cPCI chassis and measures 21.6 cm x 2.0 cm x 13.0 cm, with a lightweight design of 238 g. It features a 68-pin male SCSI I\/O connector and operates under specific power requirements of 1 W at 3.3 V and 8 W at 5 V with all crosspoints closed. The operational temperature range is from 0 °C to 55 °C, with storage capabilities spanning from -40 °C to 70 °C, and it supports relative humidity levels from 5% to 85%.","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683853422828,"sku":"778572-33","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_3c43e211-ef6f-4b3a-a6e2-15a6e1a2148e.jpg?v=1753243131","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-778572-33","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
