{"product_id":"national-instruments-rm-4339","title":"National Instruments RM-4339","description":"\u003cp\u003eThe National Instruments RM-4339 Terminal Block is a specialized rack-mount interface designed to work seamlessly with the PXIe-4339 PXI Strain\/Bridge Input Module, facilitating precise debugging and testing applications in industrial automation settings. This terminal block enhances measurement accuracy and operational flexibility with a variety of back-end and front-end connectivity options. It features two 2-pin COMBICON terminals, one 4-pin COMBICON terminal, and three 96-pin female DIN connectors at the rear. The front panel is equipped with 24 RJ50 connectors, three 9-pin D-SUB connectors, three 25-pin D-SUB connectors, and three BNC connectors, enabling versatile connections to various instruments and devices. \u003c\/p\u003e\n\n\u003cp\u003eEach of the three channels (A, B, and C) supports eight analog input channels, providing robust data capture capabilities. The device assures minimal offset voltage with a maximum of 10 μV and a typical 2 μV at 23°C ±5°C, while maintaining an outstanding stability rating of 0.5 μV\/°C. The RM-4339 accepts an external power supply ranging from 6V to 28V, with a maximum current rating of 2.4A and 100mA for each EX+ connection, demonstrating low route resistance of 0.7 Ω between the external power and EX+ channel. \u003c\/p\u003e\n\n\u003cp\u003eEngineered for reliability, the RM-4339 operates effectively in environments with temperatures between 0°C and 55°C and a relative humidity range of 10% to 90%, making it suitable for challenging conditions. It withstands random vibrations from 5 to 500 Hz and operational shocks of up to 30 g peak. The terminal block supports various bridge completion configurations, including quarter-bridge completion, with resistive values of 120 Ω, 350 Ω, and 1 kΩ, enhancing measurement precision. Additionally, it includes shunt calibration resistors (SCA) and quarter-bridge shunt calibration resistors (SCB) for improved calibration capabilities. The RM-4339 allows for concurrent connection to three NI PXIe-4339 modules, with each channel powered and controlled independently, and supports in-situ calibration, minimizing the need for disconnections during measurement error verification.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683863941356,"sku":"RM-4339","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_d0b22ed2-65a1-47d2-8a41-8f4182872537.jpg?v=1753243154","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-rm-4339","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
