The National Instruments PXI-6250 is a high-performance PXI Multifunction I/O Module engineered for precision testing at rapid rates. This module belongs to the M Series and features the advanced NI-STC 2 system controller, NI-PGIA 2 programmable amplifier, and NI-MCal calibration technology, which collectively enhance its performance and accuracy. The PXI-6250 is equipped with a high-speed NI-PGIA 2 amplifier that offers a quick settling time at high sampling rates, ensuring 16-bit resolution across all channels even under demanding conditions. To maintain optimal performance, this module has a calibration interval of two years, necessitating external calibration at least every two years.

The design of the PXI-6250 accommodates buffered data acquisition utilizing onboard FIFO memory, with data transfer to the host PC managed through DMA or interrupts. It supports the NI-DAQmx driver software, LabVIEW SignalExpress LE for data logging, and the Measurement & Automation Explorer for configuration management. Additionally, the digital lines are capable of driving loads up to 24 mA for controlling actuators and relays. With a clocking capability of 10 MHz, the digital lines can be utilized for pulse-width modulation, making the module suitable for applications involving pumps, valves, lamps, fans, and motors.

The PXI-6250 operates within a temperature range of 0 ºC to 55 ºC and can be stored in temperatures ranging from -20 ºC to 70 ºC. It withstands non-condensing humidity levels of 10% RH to 90% RH and features random vibration resilience of 0.3 grms during operation and 2.4 grms during non-operation over a frequency range of 5 to 500 Hz. Although the PXI-6250 has been designated as an obsolete product by National Instruments, it remains available for purchase and service through Apex Waves. This standard 3U PXI device weighs 7.5 oz and comes with a three-year warranty, with user and maintenance manuals accessible for download.
