National Instruments 781476-01 PXI Multifunctional I/O Module 

The part number 781476-01 from National Instruments is the identifying part number for the PXIe-6378 PXI Multifunctional I/O Module. This I/O module features 16 Analog input channels with an ADC resolution of 16 bits. The input channels have a maximum sampling rate of 3.571 MS/s and a timing accuracy of 10 ns. The module has an input voltage range of ±1 Volts, ±2 Volts, ±5 Volts, and ±10 Volts with DC input coupling. The maximum voltage for positive and negative inputs is ±11 V for all ranges, in Measurement Category I. 

The CMRR (at 60 Hz) is 70 dB and has an input signal bandwidth of 1 MHz. The input impedance during the device ON condition for AI+ to AI GND and AI- to AI GND is >100 GΩ in parallel with 100 pF. During the device OFF condition, the input impedance for AI+ to AI GND and AI- to AI GND is 2 kΩ with an input bias current of ±10 pA. The Crosstalk (at 100 kHz) on Adjacent channels is -80 dB and -100 dB on Non-adjacent channels. This 781476-01 can handle 12,268 samples shared among channels used due to its large FIFO size. To transfer data from one memory block to another this module uses DMA (scatter-gather), a programmed I/O method. 

The 781476-01 PXI Multifunctional I/O Module has 4 Analog output channels, with a 16-bit digital-to-analog converter. The output channels have Differential Non-Linearity of ± 1 LSB, max, and 16-bit guaranteed Monotonicity. The maximum update rate for all the channels when operating simultaneously is 3.3 MS/s with no minimum update rate. The slew rate of this module is 20 V/µs with 2 µs of Settling time, full-scale step, 15 ppm (1 LSB). 

This PXI multifunctional module also features 48 Digital I/O/PFI with each terminal individually programmable as input or output. The Digital I/OPFI provides voltage protection of up to ± 20 Volts on up to two pins. To operate this PXI module, it requires 8.2 Watts at 3.3 Volts or 21.8 Watts at 12 volts. This 781476-01has a Standard 3U size and weighs 241 g (8.5 oz).
