National Instruments 781052-01 PXI Multifunction I/O Module

The part number 781052-01 from National Instruments is the identifying part number for the PXIe-6341 PXI Multifunction I/O Module. This I/O module is designed to be compatible with PXI Express systems controllers and devices and can perform data acquisition tasks with high accuracy. This module features 16 single-ended analog inputs which can also be configured as 8 differential inputs. To process the analog data into digital this Multifunction I/O module features a 16-bit analog-to-digital converter which allows the input signals to be processed. 

The module has a maximum sampling rate of 500K samples per second per channel making it faster and more efficient at processing data. The module has an input signal range of ±0.2 V, ±1 V, ±5 V, and ±10 V making this module very versatile when it comes to the types of signals being processed. This module has a Common Mode Rejection ratio or CMRR of 100 dB to make sure the module processes noise-free signals. 

The 781052-01 has two 16-bit analog outputs, each channel with an update rate of 900K samples per second for one channel and 840K samples per second when both channels output data simultaneously. The outputs have a low output impedance of 0.2 Ω with a voltage range of ±10 V. Using the onboard 2,047 sample FIFO buffer memory, this I/O module can create both periodic and nonperiodic waveforms. 

The 781052-01also features 24 Digital I/O channels which can be individually programmed as inputs or outputs depending on the user's requirements. The digital I/O can perform digital filtering and signal debouncing operations and can handle high-current drives with output currents of up to 24 mA for ports 0 and 16 mA for PFI lines. The module is designed to fit into standard 3U PXI Express slots and is lightweight weighing approximately 157 grams. It can operate in an environment with an ambient temperature between 0 degrees Celsius to 55 degrees Celsius and should only be stored in an environment with a temperature of -40 degrees Celsius to 71 degrees Celsius to prevent affecting its overall performance.
