National Instruments 779626-01 PXI Multifunction I/O Module
The part number 779626-01 from National Instruments is the identifying part number for the PXI-6239 PXI Multifunction I/O Module. This data acquisition I/O module features 8 differential current analog input channels with 16-bit analog-to-digital converters for helping convert the analog signals from the actuators to digital format through digital signal processing. The input range of each channel is ±20 mA with a maximum sampling rating of 250kS per second for a faster data acquisition process.
779626-01 has an input impedance of 92 Ω ±10% with a capacitor of 100 pF connected in parallel to help lower signal loading. The module has an overvoltage protection rating of ±25 volts. In addition, it features 2 analog outputs with a 16-bit digital-to-analog converter. The channels have an update rate of 500 kilo samples per second when one single channel is being used while it is reduced to 450 kilo samples per second when both channels are used simultaneously for optimized performance.
For processing digital signals, the 779626-01 also features 10 digital I/O channels of which 6 are inputs and 4 are outputs. The digital channels have a voltage range of 0 volts DC to 30 Volts DC and have a current range of 100 mA when all the channels are being used simultaneously or 350 mA when only one channel is being used. The channels are designed for the current sinking. To help make the device run more efficiently the instrument features debouncing filters for time optimization.
Speaking of time, the 779626-01 has two 32-bit general-purpose timers/counters that can help this device perform various time-related measurements such as pulse width measurement, edge counting, and measuring the period of a signal. These timers support internal base clocks at 80 MHz, 20 MHz, and 100 kHz, with an external base clock frequency range of 0 MHz to 20 MHz. Additionally, the device can be powered using the PCI/PXI bus operating at 5 volts while drawing a current of 0.7 A or operating on a 12-volt supply and drawing 20 mA of current. This module has a compact and portable design with dimensions of 9.7 cm × 15.5 cm and weighing approximately 144 grams.
