Functional Safety M-LB-(Ex-)5000-System
Planning
The values given in the following table are calculated for 2-wire, 3-wire or 4-wire applications
as field devices are usually connected by more than one wire. For the calculation, add the
numbers from the respective column to the numbers given for the safety loop. They are already
summarized for the respective application.
Safety Function
The safety function of the surge protection barrier is to behave like a piece of copper wire,
passing through the process signal without being altered.
Reaction Time
The reaction time is < 1 ms.
Note!
The fault indication output is not safety relevant.
Note!
See corresponding datasheets for further information.
