{"product_id":"national-instruments-usb-9234","title":"National Instruments USB-9234","description":"\u003cp\u003eThe National Instruments USB-9234 is a high-performance four-channel dynamic signal acquisition module designed for precise measurements with IEPE sensors. Featuring a 24-bit ADC resolution, the USB-9234 supports a remarkable sampling rate of up to 51.2 kS\/s per channel, making it ideal for applications such as machine status monitoring and noise, vibration, and harshness (NVH) testing in automotive environments. This compact module includes software-selectable IEPE signal conditioning that provides an auxiliary 2 mA current to power microphones and accelerometers, and it accommodates a wide variety of signal inputs within a ±5 V range. The USB-9234 incorporates anti-aliasing filters that adapt to the sampling rate for enhanced measurement accuracy and includes multiple input configurations: IEPE with AC coupling, AC coupling, and DC coupling. \u003c\/p\u003e\n\n\u003cp\u003eAdditionally, the module features integrated TEDS (Transducer Electronic Data Sheet) support compliant with IEEE 1451.4 TEDS Class I to simplify sensor setup and calibration. The USB-9234 offers easy connectivity via BNC connectors and is designed to operate in harsh industrial conditions, with a wide temperature range of -40°C to 70°C and reliable performance in humid environments of 10% to 90% RH, non-condensing. Its low power consumption ensures energy efficiency, requiring a maximum of 900 mW in active mode and just 25 μW in sleep mode. The module employs both analog and digital filtering to reject out-of-band signals while accurately capturing in-band signals, ensuring data integrity with minimal passband ripple and phase nonlinearity. For coordinated sampling across multiple devices, the USB-9234 features an integrated master timebase of 13.1072 MHz, which can be synchronized with other modules. Its compatibility with single-module USB carriers, NI CompactDAQ, and CompactRIO hardware provides exceptional versatility for a variety of applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683832647916,"sku":"USB-9234","price":0.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_da92e0c5-226c-4671-8ed9-8588fbf7c396.jpg?v=1753243075","url":"https:\/\/www.industrialautomationco.com\/en-ca\/products\/national-instruments-usb-9234","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
