• Tsarin Intrinsically Safe: An tabbatar da ATEX Zone 2 gaba ɗaya don samar da haɗin kai mai aminci, kariya daga fashewa ga injinan filin.
• Daidaiton Bayanai na HART: Yana wuce canje-canjen bincike da sigogi na saiti na sakandare kai tsaye ta kan madaukai 4–20 mA na yau da kullum.
• Kulawa Ba Tare da Tsayawa Ba: Injiniyan hot-swap cikakke yana ba da damar cirewa da saka module a kunne ba tare da katse tsarukan da ke aiki ba.
• Keɓewar Tasha zuwa Tsari: Cikakkun katangar keɓewar lantarki suna toshe gurɓatattun ‘ground loop’ da tasoshin wutar lantarki masu ƙarfin gaske.
