Part Number: 778397-01
Product Description: The National Instruments PCI-6120 Multifunction Data Acquisition (DAQ) device, identified by part number 778397-01, is designed for versatile and high-performance signal acquisition. Equipped with four pseudodifferential analog input channels supporting a 16-bit resolution, the PCI-6120 can achieve a maximum sampling rate of 800 kS/s. This module features thorough signal conditioning with both DC and AC coupling options, making it suitable for applications involving mixed signals. It includes a 32 MS input FIFO buffer and supports multiple data transfer methods, including interrupts, programmed I/O, and DMA in scatter-gather mode. The PCI-6120 incorporates a 5-pole Bessel analog filter with a 100 kHz cutoff frequency, enhancing its ability to process complex waveforms.

In addition to the analog inputs, the device offers two 16-bit analog output channels with a maximum update rate of 4 MS/s for a single channel and 2.5 MS/s when using both channels. The output voltage range is ±10 V with DC coupling only. For digital interfacing, the PCI-6120 includes eight TTL/CMOS-compatible digital I/O channels, with a transfer rate of 10 Mwords/s and a high-impedance state during power-on, paired with input and output buffer sizes of 2048 bytes. The module operates at a power requirement of 3.0 A at +5 VDC (±5%) and 0.8 A at +3.3 V, with a maximum I/O connector voltage output of +4.65 VDC to +5.25 VDC at 1 A. The physical dimensions are 12.3 in. by 4.2 in., and it utilizes a 68-pin male SCSI-II connector for I/O connections. The PCI-6120 is rated for operating temperatures between 0 °C and 50 °C, with a relative humidity range of 10% to 90%, and can be stored in temperatures from -20 °C to 70 °C. This device is designed for indoor use only, with a maximum operating altitude of 2000 meters.
