National Instruments 783631-01 PXIe Multifunctional I/O Module 

The part number 783631-01 from National Instruments is the identifying part number for the PXIe-6345 PXIe Multifunctional I/O Module. This I/O module features 40 differential analog channels or 80 single-ended analog channels with an input impedance of more than 10 GΩ in parallel with 100 pF between analog input and ground during the ON state. The analog-to-digital converter on this module has a resolution of 16 bits and the sampling rate of the inputs is 500 kS/s maximum when using a single or multichannel. 

The 783631-01 Multifunctional I/O Module has one analog trigger with Start Trigger, Reference Trigger, Pause Trigger, Sample Clock, Convert Clock, and Sample Clock Timebase functions. The module has 2 analog outputs with digital-to-analog conversion capability. Each channel supports a resolution of 16 bits, allowing for precise and detailed representation of analog output signals. The module maintains a high level of accuracy, with a Differential Nonlinearity specification of ±1 Least Significant Bit (LSB). This ensures that the deviation between the ideal output and the actual output is within one LSB, contributing to accurate signal generation.

The module provides a total of 24 digital input/output channels, distributed as 8 channels labeled P0.<0..7> and 16 channels split between PFI <0..7> and PFI <8..15>. These channels can be individually addressed and utilized for digital signal processing. All channels share a common ground reference denoted as D GND, ensuring consistent electrical potential across the system. Each terminal is programmable as either an input or output, allowing for flexible configuration and control of digital signals. Input voltage protection is provided to safeguard the module against potential damage from excessive voltage levels. Each channel can withstand voltages of up to ±20 V on up to two pins. 

The recommended operating conditions for the module delineate crucial voltage and current thresholds essential for its proper functionality. Input signals above 2.2 V and below 5.25 V are identified as "high," while those between 0 V and 0.8 V are classified as "low." This module has the Standard 3U PXI dimensions and weighs approximately 198 g (7.0 oz) making the module compact.
