3.6.1
Isolation
Within the fieldbus node, there are three electrically isolated potentials:
•
Electrically isolated fieldbus interface via transformer
•
Electronics of the fieldbus couplers/controllers and the I/O modules
(internal bus)
•
All I/O modules have an electrical isolation between the electronics
(internal bus, logic) and the field electronics. Some digital and analog input
modules have each channel electrically isolated, please see catalog.
