GPH6000-MM01-EN.00

Safety Parameters

The following parameters allow for Performance Level (PL) and Safety Integrity Level (SIL) applications:

ƛ DU single channel = 3.02 x 10-6 (1/h)
MTTFd = 1/3.02 x 10-6 (1/h) = 331,125 hours = 37.7 years

(MTTFd ≃ MTBFd)

NOTE: The MTTFd value is valid only if it does not exceed the annual average number of operations in the following parameter table.
