1.4 Functional Safety (Optional)
The P16800 decouples signals from safety-related signal circuits without influencing them. The input
signal is transmitted to the output signal with the specified accuracy in a functionally safe manner.
The nameplates on the products clearly specify the product properties.
SRAC – Safety Related Application Conditions
The information regarding use of the P16800 and the conditions of use specified in this User Manual
are to be followed as safety-related application conditions (SRACs) in order to achieve the specified
functional safety characteristics regarding absence of interaction and signal transmission. The rein-
forced insulation of the SIL product between input and output and the specified limits for altitude,
overvoltage category, and working voltage must be observed.
