National Instruments 778026-01 Multifunction DAQ Device 

National Instruments part number 778026-01 is an identifying part number for the PCI-6035E a Multifunction DAQ Device. This minimal-effort DAQ board utilizes E Series technology to provide reliable measurements across a wide range of applications. Users can achieve up to 200 kS/s sample rate and 16-bit resolution with 16 single-ended or 8 differential channels. The NI 778026-01 also features two 12-bit analog outputs. Depending on the user's hard drive, the device can stream to disk at rates up to 200 kS/s. It has 8 digital I/O lines with TTL/CMOS compatibility. A ground-referenced signal source is connected to the building structure ground, making it effectively connected to a common reference point relative to this DAQ device, assuming the PC is connected to the same power system.

Non-isolated outputs of instruments and devices that connect to the building power structure fall into this category. The 778026-01 comes with a 68-pin male SCSI-II I/O connector. The 6034 and 6035 E Series devices are high-performance multifunction I/O devices for PCI, PXI, and CompactPCI bus computers. They support functions such as analog input, analog output, digital I/O, and timing I/O. 

The NI 778026-01 DAQ Device is equipped with input multiplexers. The PGIA converts multiple data signals into a single signal, representing the difference between the data signals, multiplied by the device's gain setting. This model features an A/D converter (ADC) that measures the output voltage during A/D conversions. For higher source impedances, this connection keeps the differential signal path relatively stable. The output voltage is referenced to the ground of the device. Noise associated with the ground couples electrostatically onto the positive line but not onto the negative line, maintaining the integrity of the differential signal path.
