{"product_id":"national-instruments-usb-6421","title":"National Instruments USB-6421","description":"\u003cp\u003eThe National Instruments USB-6421 is a high-performance USB Data Acquisition Device, part of the mioDAQ series, designed to meet the demands of complex test and measurement applications. This device features 16 single-ended (or 8 differential) analog input channels, 2 analog output channels capable of providing output voltages from ±10 V at a rate of 250 kS\/s\/channel, and 16 digital I\/O channels. The digital I\/O channels support a variety of functions, including triggering and clocking for the four available 32-bit counters, which are capable of pulse width, edge counting, and semi-period measurements. The USB-6421's maximum single-channel sampling rate reaches 250 kS\/s, ensuring rapid and precise data collection across multiple channels simultaneously.\u003c\/p\u003e\n\n\u003cp\u003eConnectivity is facilitated through a USB Type-C interface for bus power, and the device incorporates two 36-position spring terminal connectors that can be secured with screw flanges at a torque of 1.80 lb\/in. The USB-6421 is designed for a wide operating temperature range of 0 °C to 55 °C, and can be stored safely at temperatures between -20 °C and 70 °C. The device has compact dimensions of 116.7 mm x 177.0 mm x 30.4 mm (4.59 in. x 6.97 in. x 1.20 in.) and weighs 590 g (1.30 lb), making it highly portable. It is recommended to allow a warm-up period of 15 minutes and to calibrate the device every two years to ensure optimal performance. With published APIs and examples available for LabVIEW, Python, C\/C++, and NI's free FlexLogger Lite program, the USB-6421 is an excellent choice for versatile data acquisition applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683831042284,"sku":"USB-6421","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_0989074c-65e4-4bf2-8768-b7ed14adfa2d.jpg?v=1753243073","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-usb-6421","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
