Select Your Safety Product Now!An assessment of a safety relevant system is performed easier if the risk of failure of the relevant components is already known. For that purpose, Pepperl+Fuchs offers a large number of products with a SIL/PL assessment. On this site, choose from various selection criteria like safety integrity level, performance level, device function, and signal type to quickly find the SIL/PL assessed device that you are looking for.

More Industry-Moving InnovationsNEW! Complete SIL 3 Portfolio for All Signal Types
With the new SIL 3 output drivers, Pepperl+Fuchs has closed the last gap in its portfolio of SIL-3-certified isolated barriers. Intrinsically safe SIL 3 components are now available for all signal types—digital and analog, for control signals to the actuators and for measurement signals from the field, as devices for DIN rail mounting and as isolating components for termination boards.
For practical applications, this means that the previously necessary workaround with redundant SIL 2 components is no longer necessary for SIL 3 applications: positioners, electric valves or HART IP converters in intrinsically safe SIL 3 applications can now be connected directly to the control system with a single safety barrier.
