National Instruments 781346-01 PXI Strain/Bridge Input Module

Part number 781346-01 from National Instruments is the identifying part number for the PXIe-4330 Strain/Bridge Input Module. Featuring 8 analog input channels with 24 bits of ADC resolution, the module is an excellent choice for a range of testing applications. The 8 input channels of the 781346-01 easily handle sample rates of Up to 25.6 kS/s, and they allow the module to effortlessly integrate with strain gauge bridges and bridge based sensors. By using software, the user is able to configure each channel individually. 

Boasting a Delta-Sigma architecture that features analog prefiltering, the 781346-01 is able to achieve high-resolution measurements that encounter very low noise and distortion. The module has an operating frequency of 100 MHz with an accuracy of ±50 ppm- and it’s synchronization capabilities are achieved through the onboard reference clock source. The power requirements of the 781346-01 Strain/Bridge Input Module vary, with 1.3 A needed for a voltage of +12 V and 1.1 A needed for a voltage of +3.3 V. 

Built for optimal functionality in a variety of environmental conditions, the 781346-01 has the standard 3U PXIe dimensions of 16 cm × 10 cm (6.3 in. × 3.9 in.) and weighs in at 152 g (5.3 oz). It has an operating temperature range of 0 °C to 55 °C, and can be stored safely in a storage temperature range of -40 °C to 71 °C. 

The 781346-01 operates at altitudes up to 2,000m, and it has a pollution degree of 2.
