Failure rates and SSF for 70.1150...23 (AC240V)
Failure rates and SSF for 70.1150...25 (AC/DC24V)
The PFH and PFD
avg
values were calculated assuming that the time to restore the system is 8h (MTTR = 72h). Furthermore, the calculation was
based on a lifetime of 10 years (T
1
= 10y). The common cause factor was determined as per the tables of the DIN EN 61508 for sensor systems
and logics.
Calculations DIN EN ISO 13849-1 Performance Level PL d - Low voltage 230V
Calculations DIN EN ISO 13849-1 Performance Level PL d - Safety extra low voltage 24V
3. The MTTF
d
value of a partial system must be limited to 100 years as per the DIN EN ISO 13849-1 requirements.
