Probability of Failure on Demand Calculation To calculate the probability of dangerous failure on demand (PFD) of a safety-related function, the PFD values for all components used within this function must be taken into consideration. In the case of dual-channel applications, the AS-Interface safe input module does not significantly contribute to the PFD or PFH (probability of dangerous failure per hour) of the overall system. - Page 25 Twinsburg, Ohio 44087 · USA Tel. +1 330 4253555 E-mail: sales@us.pepperl-fuchs.com Asia Pacific Headquarters Pepperl+Fuchs Pte Ltd.
