Protokol HART petlje od 4–20 mA i izolacija kanala
Iako je prvenstveno infrastruktura kućišta, DNCF primenjuje Honeywell principe izolacije koji se koriste u HART okruženjima sa petljama od 4–20 mA. Svaki čvor dobija nezavisno napajanje preko dvostrukog napajanja čvorova (DNPWR), čime se obezbeđuje izolacija između kanala LCN modula. Ova arhitektura sprečava smetnje između redundantnih čvorova i stabilizuje komunikaciju u okviru porodice sistema TDC 3000.
Često postavljana pitanja
P: Da li DNCF kućište može biti pod napajanjem tokom umetanja modula? O: Ne, moduli se smeju umetati ili uklanjati samo kada je kućište isključeno iz napajanja, kako bi se sprečila nedefinisana stanja.
P: Koliko čvorova može istovremeno da podrži? O: Kućište podržava do dva čvora, od kojih je jedan konfigurisan sa tri ploče, a drugi sa dve ploče.
P: Kolika je maksimalna potrošnja kućišta? O: Kućište troši do 50 W pri punom opterećenju.
Smernice za instalaciju na terenu
Montirajte kućište u standardni 19-inčni rek, uz poravnanje prednjeg i zadnjeg kaveza za kartice.
Uverite se da ventilatori za prinudno hlađenje nisu blokirani kako bi se održala termička stabilnost.
Sprovedite AC ulazno ožičenje odvojeno od signalnih kablova kako biste smanjili EMI.
Proverite uzemljenje kućišta i oklopnih veza pre uključivanja napajanja.
Potvrdite adresiranje čvorova i raspodelu slotova na ploči pre instalacije.
