This PXI fault insertion switch uses solid state switching elements and is capable of carrying 40A on single channel or 30A on all channels at the same time and provides a robust solution to high current fault insertion. It is designed to be able to insert three different fault conditions between the test fixture and the equipment under test: Open-Circuit Short-Circuit between UUT connections Short-Circuit to external signals Through relays on each channel enable signals to the UUT to be set open-circuit. Fault Insertion Buses allow any channel to be shorted to any other channel and also enable any channel to be connected to an external signal such as Power, Ignition or Ground to simulate fault conditions. The module is supplied with 2 fault buses.
