“Change will Always be There”
Another argument that is clearly in favour of the Bartec system is its flexibility. "Changes and individual requests will always be there, regardless of the reason," Schirmel says. "This is where flexibility is needed. If necessary, modules can easily be added or exchanged." Antares offers one advantage in this regard, where no other remote I/O system for the Ex area can keep up: flexible system approval. Until now, no company has managed to avoid having to clearly plan its remote I/O system and install it into certified Ex e enclosures with rigid approval. Users in particular had to undergo time–consuming and costly re-certification of the entire system any time a modification was made, regardless how minor. With Antares, however, it suffices to replace the system label if the temperature should change as a result of higher power. Effective immediately, electrical planning engineers are able to freely design their system, modify and expand it as needed, and install it into a simple, mechanically protected, standard industrial enclosure.
