Emerson o hlahisa li-valve tse netefalitsoeng tsa SIL 3

Emerson o hlahisitse likopano tsa li-valve tsa pele tse fihlelang litlhoko tsa ts'ebetso ea moralo oa Safety Integrity Level (SIL) 3 ho latela maemo a IEC 61508 a Khomishene ea Machabeng ea Electrotechnical. Litlhapi tsenaDigital IsolationLitharollo tsa lintlha tsa ho qetela li sebeletsa litlhoko tsa bareki bakeng sa li-valve tse koalang lits'ebetsong tsa ts'ebetso ea ts'ireletso e matla (SIS).

Ntle le tharollo ena, basebelisi ba tlameha ho hlakisa likarolo tsohle tsa li-valve, ba reke e 'ngoe le e' ngoe, 'me ba li kopanye hore e be kakaretso e sebetsang. Esita le haeba mehato ena e etsoa ka nepo, kopano ea mofuta ona e tloaelehileng e ntse e ke ke ea fana ka melemo eohle ea kopano ea Digital Isolation.

Boenjiniere ba valve ea ho thibela tšireletso ke mosebetsi o boima. Maemo a tloaelehileng le a ferekaneng a ts'ebetso a tlameha ho hlahlojoa ka hloko le ho utloisisoa ha ho khethoa likarolo tsa valve le actuator. Ho phaella moo, motsoako o nepahetseng oa li-solenoids, li-brackets, li-couplings le lisebelisoa tse ling tsa bohlokoa li tlameha ho hlalosoa le ho lumellana ka hloko le valve e khethiloeng.
