Description
The 783865-01 is a high-precision SC Express module, specifically the PXIe-4302, designed for versatile and accurate voltage input measurements. This module supports a wide range of applications with its +/-10V, 32-channel configuration, capable of 24-bit resolution at a sampling rate ranging from 1 S/s to 5 kS/s. It utilizes a Delta-Sigma ADC and operates in a simultaneous mode to ensure precise and synchronized data acquisition across all channels.
The module features a 96-pin male DIN I/O connector, allowing for easy and secure connection to a variety of sensors and signals. Each channel is equipped with a digital filter for enhanced signal integrity, and the input coupling is DC, suitable for a wide range of measurement needs. The module also includes a 1023 samples FIFO buffer for efficient data handling and utilizes Direct Memory Access (DMA) for optimal data transfer speeds.
Robust fault protection mechanisms are in place to ensure the module’s reliability and longevity. Users are recommended to allow a 15-minute warm-up time for optimum performance and to calibrate the device at least once a year to maintain accuracy. The module exhibits exceptional temperature stability, with gain at 10 V being stable within 8 ppm/°C and offset at 10 V within 31 µV/°C.
It supports four different sample rates, providing flexibility for various application requirements. Software compatibility is broad, with support for NI-DAQmx, allowing users to program the module via LabVIEW or LabWindows/CVI, making it a versatile choice for engineers and scientists. The module’s compact physical dimensions, 6.3 x 3.9 in, ensure that it can fit into a wide range of setups without consuming excessive space.
