National Instruments 781051-01 Multifunction I/O Device 

National Instruments part number 781051-01 is an identifying part number for the PCIe-6363, a Multifunction I/O device with 48 Digital Input/Outputs, 32 Analog Inputs with 16 bit resolution and 2 MS/s maximum sample rate and 4 Analog Outputs with a maximum sample rate of 2.86 MS/s. The NI 781051-01 is a high-performance data acquisition device with analog I/O, digital I/O, and four 32-bit counters/timers for tasks such as PWM, encoder, frequency, and event counting. 

Utilizing the high-throughput PCI Express bus and multi core-optimized drivers and application software, the device ensures robust functionality. It features onboard NI-STC3 timing and synchronization technology, providing advanced timing capabilities with independent analog and digital timing engines and retriggerable measurement tasks. Ideal for a wide range of applications, from basic data logging to complex control and test automation, it includes the NI-DAQmx driver and configuration utility, which simplify both configuration and measurements. 

The part number 781051-01 does not offer simultaneous sampling and has a maximum sampling rate of 2 MS/sec. It supports input channel voltages ranging from +0.1 V to +10 V with an input impedance of over 10 GΩ. The input channels have an absolute accuracy of 1660 µV. The device features four output channels, with the maximum update rate varying based on the number of channels updated simultaneously. For one channel, the highest update rate is 2.86 MS/sec, which decreases to 1.25 MS/sec when updating four channels concurrently.
