{"product_id":"national-instruments-785641-01","title":"National Instruments 785641-01","description":"\u003cp\u003eThe National Instruments 785641-01 is a high-performance Strain\/Bridge Input Device designed for the FieldDAQ system, identified by the model number FD-11637. This device features eight analog input channels, providing galvanic isolation between each channel and the chassis to ensure reliable data acquisition. With an input range of ±38 mV\/V, the 785641-01 is equipped with a 24-bit delta-sigma ADC featuring analog prefiltering for enhanced signal fidelity. It operates in simultaneous sample mode with selectable timebase frequencies of 13.1072 MHz, 12.8 MHz, 12.288 MHz, or 10.24 MHz, achieving a maximum timing accuracy of ±30 ppm. The device supports a flexible data sampling rate, scalable from 500 samples\/s to 102.4 ksamples\/s.\u003c\/p\u003e\n\n\u003cp\u003eFor network connectivity, the 785641-01 supports both TCP\/IP and UDP protocols across multiple ports, including configuration-only ports at HTTP:80, UDP:5353, and others. It includes two internally-switched 8-pin X-coded M12 ports that auto-negotiate Ethernet communication rates of 10\/100\/1000 Mbps, with a maximum cabling distance of 100 meters per segment and support for up to 15 hops per line. The device operates on an input voltage range of 9 VDC to 30 VDC, with a maximum power consumption of 15 W and heat dissipation of 11 W, all connected through a 5-pin L-coded male M12 connector. The recommended torque for the connector is 0.6 Nm, with a maximum current rating of 10 A at the Power IN\/OUT terminals, and it is advisable to use a 16 A slow blow fuse for external overcurrent protection.\u003c\/p\u003e\n\n\u003cp\u003ePhysically, the 785641-01 measures 7.8 inches in length, 3.0 inches in width, and 1.9 inches in height, weighing 1.2 kg. It exhibits high operational durability, functioning effectively in temperatures ranging from -40 °C to 85 °C and withstanding up to 100% relative humidity. For storage, it can be kept in environments from -40 °C to 100 °C and is capable of operation at altitudes of up to 5000 meters. The device is recommended for calibration annually to ensure measurement accuracy.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683821474028,"sku":"785641-01","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_bc1d5f22-6a8b-46f1-8f88-d3196034d7d6.jpg?v=1753243051","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-785641-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
