7.5 4/8 F-DI DC24V PROFIsafe Digital Electronic Module
Conditions for achieving SIL/Category/PL
The table below lists the conditions which have to be met for achieving the various safety
categories.
Table 7- 18
Note
You can operate the various inputs of an F-DI module simultaneously in SIL2/Category
3/PLd and SIL3/Category 3 or 4/PLe. You only have to connect the inputs and assign the
parameters as shown in the following chapters.
