The 40-193 is a 7-Channel Fault Insertion switch designed
for the simulation of fault conditions in automotive systems.
It is able 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 other signals such as Power, Ignition &
Ground via Fault Insertion Bus
Through relays on each channel enable signals to the UUT
to be held open-circuit. Fault Insertion Buses allow any
channel to be shorted to any other channel and enable
any channel to be connected to an external signal such as
Power, Ignition or Ground to simulate fault conditions.
Range Description:
• 40-193-001 7 Channels, One Fault bus.
• 40-193-002 7 Channels, Two Fault buses.
The 40-193 uses miniature automotive relays with 20 A hot
or cold switching current. All relays are normally open.
