Part Number: 781346-01

The National Instruments PXIe-4330, identified by part number 781346-01, is a highly versatile PXI Strain/Bridge Input Module designed for demanding testing applications. This module features eight analog input channels, each offering 24 bits of analog-to-digital converter (ADC) resolution and capable of sampling at rates up to 25.6 kS/s. The PXIe-4330 seamlessly integrates with strain gauge bridges and bridge-based sensors, allowing for flexible channel-by-channel configuration through software. Its Delta-Sigma architecture, which incorporates analog prefiltering, ensures high-resolution measurements with minimal noise and distortion.

With an operating frequency of 100 MHz and an accuracy of ±50 ppm, the module provides precise performance backed by an onboard reference clock source for synchronization. The PXIe-4330 requires power of 1.3 A at +12 V and 1.1 A at +3.3 V. Constructed to function optimally under a variety of environmental conditions, the module adheres to the standard 3U PXIe dimensions of 16 cm × 10 cm (6.3 in. × 3.9 in.) and has a weight of 152 g (5.3 oz). It supports an operating temperature range from 0 °C to 55 °C and can be safely stored between -40 °C and 71 °C. Rated for operation at altitudes up to 2,000 meters, the PXIe-4330 has a pollution degree rating of 2, ensuring reliability in diverse applications. This module is backed by a three-year warranty and is manufactured by National Instruments (NI).
