In the process industry, Ethernet APL creates the conditions for end-to-end communication right down to the field level. This opens up new possibilities for real- time plant monitoring (condition monitoring), transparent management of the equipment in use (asset management) and optimised maintenance work (predictive maintenance). However, as connectivity increases, so too do the demands on the availability of the communications infrastructure. Based on the BLITZDUCTORconnect and DEHNpipe solutions, which are specifically tailored to Ethernet-APL, DEHN offers a protection concept that reliably protects communication and field devices against the effects of lightning and surge events.
The process industry is increasingly relying on digital communication structures to make processes more efficient, monitor plant conditions in real time and plan maintenance measures more effectively. Ethernet APL (Advanced Physical Layer) is an important foundation for this. The technology enables end-to-end Ethernet communication from field devices right through to higher-level automation and IT systems, thereby creating the conditions for modern applications such as condition monitoring, asset management and predictive maintenance.
However, these new possibilities also place greater demands on the availability of the communications infrastructure. Overvoltages, such as those caused by lightning strikes or electromagnetic interference, can affect network interfaces, field switches and field devices. This can result in communication faults, data loss or unforeseen plant downtime. DEHN offers a tailored protection concept for Ethernet APL infrastructures to meet these requirements.
The BLITZDUCTORconnect protects the trace ports on Ethernet APL field switches from the effects of lightning and surges. The solution is tailored to the specific requirements of Ethernet APL port profiles and protects key network interfaces without adversely affecting the quality of communications.
In addition, DEHNpipe is used directly on field devices. This compact surge arrester is installed at the equipment interface, protecting sensitive components where process and diagnostic data are recorded. The solution is also suitable for use in potentially explosive atmospheres, thereby supporting the safe operation of modern Ethernet APL infrastructures right down to the field level.
The combination of BLITZDUCTORconnect and DEHNpipe provides a coordinated protection solution for Ethernet APL networks. Operators benefit from increased availability of their communications infrastructure and a reduced risk of downtime, as well as reliable protection for key process and diagnostic data.
