PXI 1A Fault Insertion Switch 11-Channel
40-195-101
Relay
The 40-195 is a 22 Channel Fault Insertion Switch, primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert different fault conditions on pairs of signals between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Relays in-line with the signal paths allow open circuit conditions to be simulated on either side or both sides of a signal pair. Relays between each channel pair enable adjacent signals to be shorted, and relays between signal paths and the "Fault" connection allow the application of external user applied fault conditions.
