National Instruments 783634-01 Multifunction I/O Module

The National Instruments 783634-01 Multifunction I/O Module (PXIe-6375 offers a versatile solution for high performance data acquisition and control tasks. It features an extensive array of analog and digital inputs/outputs that are designed for precise and reliable measurements across a broad range of applications. The module supports 104 differential or 208 single ended analog input channels with a 16 bit ADC resolution that ensures high accuracy. It operates with a maximum single channel sample rate of 3.846 MS/s. The analog input range is adjustable supporting various voltage ranges from ± 0.1 V to ±10 V with a maximum working voltage of ± 11 V relative to AI GND. The module's digital I/O capabilities include 24 channels each individually programmable as input or output. These channels support waveform generation and acquisition with a sample clock frequency of up to 10 MHz. The module’s digital lines are protected against overvoltage conditions tolerating up to ± 20 V on two pins.

The NI 783634-01 model includes two channels with a 16 bit DAC resolution for analog output supporting output ranges of ± 10 V and ± 5 V. It provides a maximum update rate of 2.86 MS/s for one channel. The onboard FIFO buffers facilitate non periodic waveform generation and periodic waveform regeneration from either the onboard FIFO or the host buffer. The multifunction I/O module also integrates four 32-bit general purpose counters/timers capable of performing various measurements such as edge counting, pulse width and frequency division. The counters are supported by dedicated DMA controllers. 

The 783634-01 module is equipped with advanced timing and synchronization features thanks to the onboard NI-STC3 technology. This allows for independent timing of analog and digital operations as well as retriggerable measurement tasks which is essential for synchronized, multi channel data acquisition. In addition, it is designed for use in PXI Express systems leveraging the high throughput of the PCI Express bus. It requires a power supply of +12 V (19.8 W) and +3.3 V (1.6 W) and operates within a temperature range of 0 to 55 ºC. The device's robust design includes operational shock resistance and vibration tolerance that ensures reliable performance under demanding conditions.
