The 40-193 and 40-194 modules provide a compact solution for simulating both high and low-current faults when testing control systems
Pickering Interfaces has added the 40-193 and 40-194 to its range of PXI Fault Insertion solutions The new modules provide a compact solution for simulating both high and low-current faults when testing control systems, which is especially useful in a Hardware-in-the-Loop (HILS) test applications

Pickering Interfaces has a range of BRIC second-generation PXI multislot matrix modules.
Each module supports seven channels which faults can have injected.
Each channel can be opened (to simulate an open circuit) or shorted to one of two fault connections (such as ground or battery supply).
Channels can also be shorted together to simulate other types of wiring faults.
With a current rating of 20A at 16V DC, both modules are ideally suited to automotive applications.
The 40-194 version has additional circuitry making it capable of switching both high-current and low-current loads, overcoming the problem of high current relays, which require a minimum current to wet the contacts after prolonged hot switching events.
Each module has been designed to ensure robust operation over many test cycles and each allows faults to be hot switched into the system while tests are running, perfect for finding controller system response to intermittent fault occurrences.
Both modules include software support for LabView RT and QNX real-time operating systems.
