The National Instruments 782608-01, also known as the USB-6003 Multifunction I/O Device, provides versatile data acquisition capabilities suitable for various industrial applications. This device supports 4 differential or 8 single-ended analog input channels connected to a high-performance successive approximation-type ADC, delivering a 16-bit resolution. The analog inputs achieve a maximum sample rate of 100 kS/s and possess a FIFO size of 2047 samples, with an analog bandwidth of 300 kHz. Additionally, the device includes two analog outputs linked to a 16-bit DAC, offering a voltage output range of ±10 V and an identical FIFO size, supporting a maximum update rate of 5 kS/s per channel in simultaneous, hardware-timed operations.

The USB-6003 features a timebase frequency of 80 MHz with a timebase accuracy of ±100 ppm and a timing resolution of 12.5 ns. Digital I/O capabilities include 13 digital lines—8 in Port 0, 4 in Port 1, and 1 in Port 2—allowing individual configuration of channels as input or output, with programmatic selection between open collector or active drive output types. The acceptable voltage range for digital I/O is -0.3 V to 5.5 V relative to D GND.

Moreover, the USB-6003 integrates a 32-bit resolution counter designed for edge counting with a maximum input frequency of 5 MHz and pulse widths of at least 100 ns for high and low signals. The device is powered by a +5 V source with an output tolerance of ±3%, offering up to 150 mA of current while incorporating robust electrical protection features, including overcurrent protection up to 200 mA and overvoltage protection of ±20 V. The device communicates via a USB Full Speed bus with a data transfer rate of 12 Mb/s, facilitated by a USB Micro-B receptacle and 16-position screw terminal plugs for seamless I/O connections.
