Pickering Intros Fault Insertion Modules
Fault insertion module.
Clacton on Sea, UK — Pickering Interfaces has introduced two new modules, the 40-193 and 40-194. 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. Each module supports 7 channels into which faults can be 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 16VDC, both modules are suitable for 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, for finding controller system response to intermittent fault occurrences. Both modules include software support for LabView RT and QNX Real Time Operating Systems.
