The 40-202 is a 22 or 11 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 xture and the equipment under test:
• Open-Circuit
• Short-Circuit between signal pairs
• Short-Circuit between signal pairs and user applied signals
such as Power or Ground.
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 fault conditions.
The switching topology of the 40-202 allows switching channels to
be interconnected so that complex fault insertion systems can be
constructed.
