and replace the fuse to get the device back to normal operation after a transient
event. This is not convenient in many applications, which is why the STS.01 is a
superior option.
A short-circuit test is also defined in ISO 16750-2, Section 4.10, where all inputs and
outputs must be tied to the power source and then to ground for a duration of 60
seconds each. This verifies there is no damage to the device when the user
accidentally connects an I/O line to the wrong terminal. The STS.01 completed all of
these tests assuming a 24V system, resulting in a very robust device.
Refer to ISO 16750-2, ISO 7637-2, and ISO 7637-3 for a complete list of
specifications. The STS.01 successfully meets all of the requirements defined.
