Description
The product detailed herein is the NI PXI-6281, part number 191501G-03L (779121-01), categorized under PXI Multifunction DAQ devices. This model is designed to deliver a robust set of features including 16 analog input (AI) channels, 24 digital I/O (DIO) channels, and 2 analog outputs (AO). It is equipped with a resolution of 18 bits on the analog inputs and can achieve a maximum sample rate of 625 kS/s for AI.
The device requires arming for counter input/output functions and supports pause triggers in edge counting and continuous pulse generation. Additionally, it includes a programmable debouncing filter for enhanced performance. The onboard oscillator operates at a frequency of 40 MHz.
Software compatibility is extensive, supporting NIDAQmx, LabVIEW, and LabWindows/CVI, which facilitates integration into various development environments. The PXI-6281 is recommended to have a warm-up time of 15 minutes before use and should undergo calibration at least once every two years to maintain accuracy.
The device weighs 7.9 oz and is designed to operate within a temperature range of 0 ºC to 55 ºC, with a storage temperature range from -20 ºC to 70 ºC. It can function in a humidity range of 10% RH to 90% RH (noncondensing), ensuring reliability in varied environmental conditions.
