The 40-197 is a 34 Channel Fault Insertion switch, primarily designed
for routing simulated fault conditions in automotive and aerospace
applications involving the reliability testing of safety critical controllers.
A low cost 16 Channel option is also available.
It is designed to be able to route different fault conditions between the
test xture and the equipment under test, including:
• Open-Circuit
• Short-Circuit between UUT connections
• Short-Circuit to other signals such as Power, Ignition & Ground via
fault buses
Through relays on each channel enable signals to be held open-
circuit. Four fault insertion buses allow channels to be shorted
together or to be connected to an external fault condition such as
power, ignition or ground.
For further exibility, each fault bus includes a changeover switch
to select one of two external fault conditions.
The default state of the unit is with all through relays closed and all
fault insertion relays open, giving an un-interrupted path between
the test xture and the equipment under test.
