The 40-480 is designed to simulate the operation
of automotive switches where dirty contacts
or leaking current can be expected from switch
contamination. It allows automotive I/O devices
to be tested for correct operation under adverse
conditions. The design includes protection circuits
that ensure module damage cannot be caused
by wiring faults or UUT failures. Each module can
support up to 32 channels and is suitable for both
12 V and 42 V automotive applications.
Using the simulator, the sensor control systems
used in automotive application can be checked for
their tolerance of switches working in the difficult
operating conditions found with automotive
applications.
