National Instruments 779675-01 Multifunction I/O Device

National Instruments part number 779675-01 from is the identifying part number for the USB-6210 Multifunction I/O Device. It features 8 differential or 16 single ended input channels with a 16-bit ADC resolution, and it's maximum single-channel and multichannel sampling rate is 250 kS per second with no minimum sample rate. The input impedance of the 779675-01 is less than 10 GΩ in parallel with 100 pF when the device is ON while 1,200 Ω when the device is OFF and has an input bias current of ±100 pA. Thus, these features, ensure high accuracy and minimal interference in signal measurement applications. The high impedance when powered on and low bias current make it suitable for precision measurements, while the lower impedance when off necessitates careful handling to maintain signal integrity. It has overvoltage protection for all analog input and sense channels of up to ±30 V with the device ON and ±20 V with the device OFF.

This Multifunction I/O Device attributes to 4 digital input and output channels that are PFI configurable. The digital input channels are labeled as PFI 0 to 3, which correspond to P0.<0..3>, while the digital output channels are labeled as PFI 4 to 7, corresponding to P1.<0..3>. This configuration allows users to easily manage and utilize the digital I/O lines according to their specific needs. This module has 2 32-bit counter/timers with counter measurement of edge counting, pulse, semi-period, period, and two-edge separation. Its FIFO buffer size is 1,023 samples and has a data transfer method USB Signal Stream, programmed I/O.
  
The 779675-01 module has physical dimensions of 16.9 cm × 9.4 cm × 3.1 cm (6.65 in. × 3.70 in. × 1.20 in.) including the 2 16-position combicon I/O connector and Series B receptacle USB connector. It weighs 206 g (7.2 oz). This device is also incorporated with calibration tools including the 15 minutes warm-up time and a one year calibration interval determining its accuracy, reliability, and overall performance. In terms of ambient temperature, it is required to be operated at 45 degrees Celsius and should stored at a temperature of -20 to 70 degrees Celsius with a relative humidity level of 10% RH to 90% RH, non-condensing.
