National Instruments 779063-01

The National Instruments part number 779063-01 corresponds to the PXI-6143 Multifunction I/O Module, engineered for versatile signal acquisition tasks. This module features eight differential input channels, each equipped with a 16-bit analog-to-digital converter (ADC) for high-resolution data capture. Programmable input ranges of ±5 V facilitate the handling of diverse signal levels. With a maximum sampling rate of 250 KS/s and a precise internal time base accuracy of ±50 ppm, this device provides both flexibility and rapid data acquisition capabilities. The module is equipped with a FIFO buffer of 2,046 samples and supports multiple data transfer methods, including DMA, interrupts, and programmed I/O.

Physical dimensions are compact at 15.5 cm x 10.6 cm (6.10 in. x 4.17 in.), and it features a 68-pin VHDCI I/O connector, allowing seamless integration with various digital devices. Operating conditions range from 0 to 50 degrees Celsius and a relative humidity of 10% to 90% (non-condensing), with a storage temperature of -20 to 70 degrees Celsius and humidity of 5% to 95% (non-condensing).

In addition to its eight digital I/O lines, compatible with TTL/CMOS and capable of handling input voltages from 2.2 to 5 V, the PXI-6143 includes two 24-bit general-purpose counters/timers with a base clock frequency of 20 MHz and a maximum source frequency of 20 MHz, ensuring accurate timing and pulse generation. The module is designed to withstand operational shocks of 30 g peak (tested per IEC-60068-2-27) and can endure random vibrations of 5 to 500 Hz at 0.3 grms during operation and 2.4 grms when not operational (tested per IEC-60068-2-64). Power requirements are 40 mA at +5 VDC, 140 mA at +3.3 VDC, 150 mA at +12 VDC, and 80 mA at -12 VDC, making the PXI-6143 a robust choice for demanding industrial applications.
