National Instruments 779810-01 Multifunction I/O Device  

The part number 779810-01 from National Instruments is the identifying part number for the PXI-6289 Multifunction I/O Device. This module features 32 single-ended analog input channels which can be configured as 16 differential input analog channels. For processing the analog signal in the digital format, the multifunction device has an analog-to-digital converter at the input with a resolution of 16 bits for accurate digital conversion of the signal. To create an accurate digital representation of the analog signal the sampling rate of this module is 250 kS/s for single channel as well as multichannel operation. The signals this module can input have a voltage range between -0.2 volts to 0.2 volts for low-level sensitive voltages while for higher amplitude signals the voltage range is from -10 to 10 volts. To help minimize noise and ensure accuracy, this module has a high input impedance with a 110 dB CMRR ratio.

The 779810-01 Multifunction I/O Device features 2 analog output channels which convert the signal back to analog format with the help of a 16-bit Digital to Analog converter. The module can generate output signals at a rate of 83300 samples per second per channel. The output voltages of the channels are programmable and can be adjusted within the range of -10 to 10 volts. The outputs are also low impedance with a value of 0.2 Ω and can drive external components with a current of up to 5 mA. This module features 48 Digital I/O which are user-programmable and are available on ports 0 and Port 1 & 2 of the module. Users can program these digital I/Os to be used as inputs or outputs. The digital lines support 5 V TTL/CMOS logic levels and include pull-down resistors to ensure defined logic states when not actively driven.

The module includes two 32-bit general-purpose counters/timers capable of performing various measurements, including positive edge or negative edge counting, measuring pulse width of the signals, measuring the period, and two-edge separation operation. It also supports quadrature encoder inputs for position measurements. The onboard frequency generator can produce square waves with 10 MHz and 100 kHz base clocks, divided by any integer from 1 to 16. 

The 779810-01 Multifunction I/O Device is compatible with NI-DAQmx driver software, providing a comprehensive API for configuring, controlling, and acquiring data from the module. The software integrates seamlessly with development environments like LabVIEW, LabWindows/CVI, and . NET.
