Webfact the hardware fault tolerance is 0 (HFT=0) and considering the achieved SFF, which is smaller than 90%, the devices fulfil the requirements for the hardware integrity up to SIL 2 of IEC 61511-1, table 6 and IEC61508-2, table 2. Safety function: Sensing of the position of valves or actuators. Certified up to SIL 2. Model Series . λ. 1/h ... http://www.iesystems.com.au/wp-content/uploads/2024/06/Achieving-Hardware-Fault-Tolerance-Updated-Nov-2016.pdf WebPFD needs for SIL 3 and all of the hardware fault tolerance (HFT) requirements for SIL 3 as a simplex (HFT = 0, 1oo1) device but SC = 2, then this only meets the overall requirements of SIL 2. The SC that an element can achieve is defined during the element design phase; therefore, it is applicable to a HFT of 0. cheap flights from nashville to honolulu
