PXIe-7891 KU060 FPGA Signal-Level HIL I/O Module
The PXIe-7891 is a high-performance PXI Express FlexRIO multifunction I/O module designed for signal-level inverter hardware-in-the-loop testing. It combines simultaneous analog input, conventional and low-latency analog output, digital I/O, high-speed serial connectivity and a user-programmable Xilinx Kintex UltraScale KU060 FPGA.
The module is optimized for validating traction-inverter and electronic control-unit behavior. Its FPGA can execute multiple real-time motor models while its low-latency outputs emulate motor voltage and current feedback, resolver signals, Hall sensors, encoders and other electrical interfaces used by an inverter controller.

Use 787714-01 when requesting a quotation for the complete PXIe-7891. The assembly number identifies the internal hardware revision, while 788790-01 is a service and calibration fixture rather than an operating accessory.
Understanding the Analog Output Configuration
NI sources describe the PXIe-7891 as providing 64 total voltage-output channels across its analog-output subsystems. Application documentation divides these resources into conventional resolver-emulation outputs and 32 independent low-latency outputs for motor voltage and current emulation.
Some abbreviated NI product titles list 16 AO plus 32 low-latency AO, while module certification and detailed product attributes identify 64 total AO resources. Confirm the exact connector-to-channel mapping and required FPGA personality when planning fixture wiring.
