National Instruments PXIe-7890 PXI Multifunction I/O Module

The PXIe-7890 (Part Number: 787713-01) from National Instruments is a powerful FlexRIO Multifunction I/O Module that uses signal-level inverters for hardware-in-the-loop (HIL) applications. This module offers versatile connectivity, boasting two SFF-8436 compliant QSFP connectors on the front panel to facilitate high-speed serial interfacing. In addition, the front panel of the NI PXIe-7890 features five 68-Pin VHDCI connectors for digital I/O, analog input, analog output, and low-latency analog output functions. Equipped with a Kintex Ultrascale FPGA (KU060), this multifunction I/O module can be configured to meet the needs of a variety of test and measurement applications. 

By combining the utility of the analog input, digital I/O, and low latency analog output with the FPGA, the PXIe-7890 is capable of accommodating a number of traction motor types. As a result, it is an incredibly useful tool for obtaining complete test coverage and recreating real-world simulations by both validating and verifying the function of electronic control units. The digital I/O of the module has 64 pins, facilitating a range of functions including transmitter inverted data input, receiver inverted data output, low power mode, and connection to the +3.3 V power supply.

The PXIe-7890 can be easily fitted into a compatible chassis and secured with the is made easy with the module’s front-panel mounting screws. By tightening both the top and bottom mounting screws of the device, the user is able to strengthen the mechanical stability of the device, which in turn enhances the electromagnetic performance and signal quality.

As part of the FlexRIO family of products, the NI PXIe-7890 is equipped with NI Measurement & Automation Explorer (MAX) and the NI FlexRIO driver. This software makes it easy to program the module, which is compatible with ADEs including LabVIEW and LabWindows. 

Designed specifically for indoor use, the PXIe-7890 multifunction I/O module should be operated in environments where the temperatures range from 0 °C to 55 °C, with a noncondensing humidity range of 10% to 90%. When nonoperational, the module can be safely stored in an even wider temperature range of -40 °C to 71 °C, with a noncondensing humidity range of 5% to 95%.
