{"product_id":"national-instruments-778739-01","title":"National Instruments 778739-01","description":"\u003cp\u003eThe National Instruments part number 778739-01, also referred to as the PXI-2529, is a high-density PXI matrix switch module optimized for the stringent demands of automated test environments. It offers versatile configuration options, supporting an 8x16 or 4x32 2-wire matrix depending on terminal block accessories. Equipped with electromechanical relays, the module ensures minimal thermal offset, allowing for reliable low-voltage measurements while maintaining exceptional performance in high-power signal switching applications. Designed to handle a maximum switching voltage of 150V between channels and to ground, the 778739-01 is suitable for a variety of testing scenarios; however, caution is advised when switching inductive loads, as high-voltage transients may exceed the module’s rated limits, potentially impacting relay life and overall functionality.\u003c\/p\u003e\n\n\u003cp\u003eThis module provides a maximum switching power of 30W (or 37.5 VA) and can manage a maximum switching current of 1A and a maximum carry current of 2A per channel, making it ideal for reliable high-power signal routing. Furthermore, the PXI-2529 demonstrates impressive RF performance, with crosstalk values recorded at less than -80 dB at 10 kHz, -65 dB at 100 kHz, and -50 dB at 1 MHz, alongside a single crosspoint bandwidth exceeding 10 MHz in a 50 Ω system. Such specifications guarantee minimal cross-channel interference, which is critical for maintaining signal integrity and achieving precise measurements.\u003c\/p\u003e\n\n\u003cp\u003eFor triggering functions, the module is equipped with input and output triggers sourced from PXI trigger lines 0 through 7, featuring a minimum pulse width of 150 ns. The front panel voltage is +3.3 V TTL at a nominal current of 8 mA, with the output trigger pulse width being software-selectable, ranging from 1 µs to 62 µs, enhancing the module's versatility in various testing applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683853652204,"sku":"778739-01","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_55f24707-39d7-4f97-aea3-f1a29e11f187.jpg?v=1753243131","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-778739-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
