National Instruments 781052-01

The National Instruments part number 781052-01 designates the PXIe-6341 PXI Multifunction I/O Module, engineered for enhanced compatibility with PXI Express system controllers and devices while delivering high-precision data acquisition capabilities. This versatile module incorporates 16 single-ended analog input channels that can be reconfigured as 8 differential inputs, utilizing a 16-bit analog-to-digital converter to efficiently process input signals. With a maximum sampling rate of 500 kS/s per channel, the PXIe-6341 excels in rapid data acquisition tasks. The module supports input signal ranges of ±0.2 V, ±1 V, ±5 V, and ±10 V and features a Common Mode Rejection Ratio (CMRR) of 100 dB, ensuring the integrity of processed signals by minimizing noise interference. On the output side, the module is equipped with two 16-bit analog output channels, achieving an update rate of 900 kS/s for a single channel and 840 kS/s when both channels are active. These outputs are characterized by a low output impedance of 0.2 Ω and a voltage range of ±10 V. The onboard 2,047-sample FIFO buffer facilitates the generation of both periodic and nonperiodic waveforms. Additionally, the module incorporates 24 programmable Digital I/O channels, which allow for flexible configuration as either inputs or outputs, supplemented by digital filtering and signal debouncing features. These digital channels can drive high current loads, with a maximum output current of 24 mA for ports 0 and 16 mA for PFI lines. Designed to occupy standard 3U PXI Express slots, the PXIe-6341 has a compact form factor, weighing approximately 157 grams. It operates within an ambient temperature range of 0 to 55 degrees Celsius and should be stored in conditions ranging from -40 to 71 degrees Celsius to maintain optimal performance.
