Bus topology Profibus PA according to FISCO - Fieldbus Intrinsically Safe Concept
Extensive systems as existing in bulk chemical, tank farms or petrochemical industry are automated in most cases with proven Namur-valve technology directly to the process actuators.
These are usually in some distance to the next process control station. Thus, there are areas with a very low number of control valves and position feedbacks. To keep the wiring efforts low and to avoid error sources the connection of these individual binary signals is established via a fieldbus, i.e. Profibus PA.
MEYLE offers concepts and systems for Ex Area using the technical knowledge of our application engineering team and components from market leading German manufacturers.
