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 12V and 24V automotive applications.
