Pickering Interfaces, a provider of modular solutions for switching and signal simulation for electronic testing and verification, extends its range of modules in PXI format for fault insertion typically used in Hardware-in-the-Loop (HIL) simulation applications for the validation of electronic control units.
The 40-202 PXI Fault Insertion Switches are available with 22 or 11 fault insertion channels capable of switching currents of 2A.
It was primarily designed to simulate fault conditions in automotive and avionics test applications involving reliability testing of safety-critical control units.
These PXI modules meet differential signalling requirements. They offer the possibility of inserting three different types of fault conditions between the test fixture and the unit under test: open circuit, short circuit between signal pairs and short circuit to user applied fault conditions such as power or ground.
The relays integrated in these modules can simulate open circuit conditions on either side or both sides of a signal pair.
Relays between each channel pair allow adjacent signals to be short-circuited, while relays between signal paths and the faulted connection allow external fault conditions to be applied.
The switching topology of the 40-202 fault insertion modules allows the interconnection of the switching channels to design a complex fault insertion system.
The 40-202 series integrates Pickering’s eBIRST solution to identify faulty module relays. Pickering’s Switch Path Manager software can also be used to simplify signal routing within complex switching systems.
All Pickering Interfaces products are guaranteed for three years.
