Linking the DP/PA Coupler into the System
Uses of the DP/PA Coupler
The DP/PA coupler is available in two versions:
S
DP/PA coupler Ex [i]: You can attach all field devices certified for
PROFIBUS-PA and that are located within the hazardous area.
S
DP/PA coupler: You can attach all field devices that are certified for
PROFIBUS-PA and that are outside the hazardous area.
The DP/PA coupler is an accompanying component according to EN 50014 or
EN 50020 and must be installed outside the hazardous area.
