National Instruments PXIE-7891 FlexRIO Multifunction I/O Module
The National Instruments PXIE-7891 (part number: 787714-01) is a FlexRIO Multifunction I/O Module designed to be used with hardware-in-the-loop applications. Featuring 16 analog input, 16 analog output, and 64 digital I/O channels- the PXIE-7891 handles testing applications with ease. Boasting a reconfigurable KU060 FPGA with 38 Mb of embedded Block RAM, the module is well equipped to handle a variety of traction motor types.
Two ports are the focus of the PXIe-7981’s front panel- Port 0 and Port 1. Both of these ports are equipped with QSFP connectors, and they each support a data rate that ranges from 500 Mbps to 5 Gb/s. The onboard DRAM of the PXIE-7891 has 4 GB of memory, which is distributed equally across 2 banks. The clock rate of the DRAM is 1064 MHz, while its physical bus width is 32 bits. Using LabVIEW FPGA reduced the DRAM clock rate to 267 MHz, while the bus width is expanded to 256 bits per bank.
Of all of the features of the PXIE-7891, its digital I/O capabilities stand out. 64 DIO channels use a single-ended signal type, each with a latency of 25 ns and direction control. The module allows the digital input and output voltages to be selectively set to either 3.3 V or 5 V by going through a bank of 16 channels.
The PXIE-7891 can be used to attain complete test coverage and recreate real-world simulations, such as ECU performance validation and verification. The module is compatible with both electrical and optical high-speed cable options, though the power requirement for using optical cables is 3.3 V. The dimensions of the PXIE-7891 measure 4.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) without connectors, and it weighs in at 778 g (27.4 oz).
