40-191 6-Channel Fault Insertion Switch
Schematic Diagram
The 40-191 is a 6 Channel Fault Insertion switch designed
for the simulation of fault conditions in automotive systems.
It is capable of carrying 40 A on single channel or 30 A on all
channels simultaneously and provides a robust solution to
high current fault insertion.
It is designed to insert 3 different fault conditions between the
test fixture and the equipment under test:
• Open-Circuit
• Short-Circuit between UUT connections
• Short-Circuit to external signals
Channel through relays enable signals to the UUT to be set
open-circuit. Two fault insertion buses can be used to short
channels together or connect a channel to an external signal
such as power, ignition or ground to simulate fault conditions.
The 40-191 uses solid state switching capable of withstanding
inrush current greater than 120 A and peak voltage of 40 V.
With an indefinite number of switching operations the 40-191
can hot switch AC or DC with no life degradation.
