National Instruments 783634-01

The National Instruments 783634-01 Multifunction I/O Module, also known as the PXIe-6375, is an advanced solution designed for high-performance data acquisition and control applications. This module offers a wide range of functionalities, featuring 104 differential or 208 single-ended analog input channels with a 16-bit analog-to-digital converter (ADC) resolution, ensuring exceptional precision in measurements. It achieves a maximum single-channel sample rate of 3.846 MS/s, with an adjustable input voltage range from ±0.1 V to ±10 V, and a maximum working voltage of ±11 V relative to AI GND. The digital I/O functionality includes 24 programmable channels that can be configured as either input or output, supporting waveform generation and acquisition at sample clock frequencies of up to 10 MHz, with overvoltage protection tolerating up to ±20 V on two pins.

The module is also equipped with two analog output channels featuring a 16-bit digital-to-analog converter (DAC) that supports output ranges of ±10 V and ±5 V, along with a maximum update rate of 2.86 MS/s for one channel. It incorporates onboard FIFO buffers for non-periodic waveform generation and periodic waveform regeneration, enabling flexible and efficient data handling. Furthermore, the 783634-01 includes four 32-bit general-purpose counters/timers that can perform various tasks including edge counting and pulse width measurement, supported by dedicated direct memory access (DMA) controllers.

Enhanced with NI-STC3 technology, this module provides advanced timing and synchronization capabilities, allowing for independent analog and digital operation timing as well as retriggerable measurements essential for synchronized multi-channel data acquisition. Designed for integration into PXI Express systems, it utilizes the high throughput capabilities of the PCI Express bus, requiring a power supply of +12 V (19.8 W) and +3.3 V (1.6 W). The device operates within a temperature range of 0 to 55 ºC and features a robust design that includes operational shock resistance and vibration tolerance, ensuring reliable performance even in challenging environments. With a standard 3U PXI form factor and a weight of 208 grams (7.3 oz), the 783634-01 is a powerful asset for any advanced control system.
