The National Instruments PXI-2514 is a PXI Signal Insertion Switch Module designed specifically for hardware-in-the-loop (HIL) applications and electronic dependability testing. This Fault Insertion Unit (FIU) features a robust architecture with a set of direct-feed channels that can be selectively opened or closed to one or more failover buses, supporting symmetrical open or interfered connections, and allows for faults such as shorts between pins, battery voltages, and grounds on a per-channel basis. When utilized in conjunction with the LabVIEW Real-Time Module, the PXI-2514 (Part Number: 778572-14) becomes an indispensable tool for validating the reliability of control frameworks, including Engine Control Units (ECUs) and Full Authority Digital Engine Controls (FADECs).

Each module is capable of sending and receiving triggers via the PXI-2514 backplane, enabling input triggers to efficiently advance the switch to a designated fault area as defined within a preloaded list. This functionality also allows for output triggers to initiate measurements on various instruments throughout the PXI-2514 system. Additionally, real-time simulations can be leveraged to sequentially navigate through fault conditions, ensuring comprehensive automated test coverage. For users needing more intricate sequencing and dynamic fault management, a PXI-2514 field-programmable gate array (FPGA) module can be integrated to facilitate trigger communications with multiple FIUs through the PXI backplane.

In a Windows environment, the PXI-2514 supports interactive configuration and testing of PXI switches with the NI-SWITCH Soft Front Panel. For automated processes, the included NI-SWITCH hardware driver provides seamless access to the full capabilities of each module, allowing users to manipulate connections individually or download output lists to implement hardware-timed sequences.

Although the PXI-2514 entered the National Instruments Maintenance phase on June 30, 2022, it remains available through Apex Waves, which will continue to buy, sell, and repair end-of-life NI hardware indefinitely.
