National Instruments PXI-6239 PXI Multifunction I/O Module
The PXI-6239 (part number: 779626-01) from National Instruments (NI) is a PXI Multifunction I/O Module that can perform both single and multiple A/D conversions with a fixed or infinite number of samples. A huge first-in, first-out (FIFO) buffer contains information amid AI acquisitions to guarantee that no information is lost. The gadgets can deal with various A/D conversion tasks with DMA, interrupts, or programmed I/O. This model offers an A/D converter (ADC), which digitizes the AI signal by changing the analog voltage into a digital number. The digital isolators over the isolation barrier give a ground break between the isolated analog front end and the earth/chassis/building ground.
In the PXI-6239, the input range refers to the input voltages or currents that an analog input channel can digitize with the predefined exactness. The NI-PGIA amplifies or attenuates the AI signal depending on the input range. The user can independently program the input of every AI channel on the M Series module. An expansive input range can suit an extensive signal variation but reduces the estimation resolution. Picking a less substantial data range enhances the measurement resolution, but it may result in the input signal going out of range.
The NI PXI-6239 can examine different channels at high rates and digitize the signals precisely. However, the user should consider a few issues when designing the estimation framework to guarantee the high exactness of estimations. In multichannel scanning applications, precision is influenced by settling time. When the M Series gadget changes, starting with one AI channel and then moving on to the next AI channel, the gadget arranges the NI-PGIA with the data range of the new channel.
Designed for indoor use only, the PXI-6239 has an operating temperature range of 0 ºC to 55 ºC and a storage temperature range of -20 ºC to 70 ºC. The dimensions of the module are the same as a standard 3U PXI board, and it weighs in at 144 g (5.1 oz). This multifunction I/O module is equipped with a 37-pin D-SUB I/O connector.
The PXI-6239 is now obsolete and no longer available from National Instruments, but the Multifunction I/O Module will remain available in perpetuity for purchases or repairs with Apex Waves!
