The National Instruments PXIe-6124, identified by part number 780536-01, is a high-performance PXI Multifunction I/O Module designed for demanding measurement and control applications. This module features four differential analog input channels, offering 16-bit ADC resolution and a maximum sampling rate of 4 MS/s per channel. It boasts an input impedance of less than 100 GΩ in parallel with 10 pF and a minimal input bias current of ±10 pA. The maximum working voltage for all analog input channels is ±11 V, equipped with overvoltage protection for voltages up to ±36 V.

The PXIe-6124 includes FIFO memory with a capacity of 16,382 samples, facilitating efficient data transfer through DMA (scatter-gather), interrupts, and programmed I/O methods. Additionally, it maintains low crosstalk levels of -100 dB at 100 kHz, ensuring minimal interference between channels. This module houses two 32-bit counter/timers capable of edge counting, pulse measurements, semi-period, period, and two-edge separation with an internal base clock frequency of 80 MHz, 20 MHz, and 0.1 MHz, while supporting an external base clock frequency of 0 to 20 MHz.

Power requirements for the PXIe-6124 include 1.5 A at +12 V and 1.2 A at +3.3 V, with power availability at the I/O connector rated at +4.65 to +5.25 VDC, 1 A. Physically, the module measures 16 cm x 10 cm (6.3 in x 3.9 in) and features a 68-pin VHDCI I/O connector. It is designed to operate at an altitude of up to 2000 meters with pollution degree of 2 and in ambient temperatures ranging from 0 to 55 degrees Celsius, compliant with the IEC-60068-2-1 standard. The relative humidity specification allows for operation within 10% to 90%, non-condensing, and the module has a storage temperature rating of -40 to 71 degrees Celsius, adhering to MIL-PRF-28800F class 3 limits.

Engineered for resilience, the PXIe-6124 withstands operational shocks of 30 g peak (half-sine, 11 ms pulse) and random vibrations of 5 to 500 Hz at 0.3 grms, with non-operating vibrations rated at 5 to 500 Hz, up to 2.4 grms, making it suitable for challenging industrial environments.
