Description of the “Safe State”, relay output
Contact open (relay de-energized)
Relay lifetime (Note2)
100 000 times
Note1: The 9116 contains no lifetime limiting components, therefore the PFH figures are valid
for up to 12 years, according to IEC 61508.
Note2: The user must calculate the product lifetime with regard to the relay lifetime.
