Daidaitawar Electromagnetic Electromagnetic (EMC): Kowane tashar fitarwa tana haɗa abubuwan kariya ta EMC, yana tabbatar da ingantaccen aiki a cikin matsanancin yanayin lantarki na masana'antu.
4. Haɗin Tsari da Daidaitawa:
An tsara shi don S800 I / O: Daidai yana haɗawa cikin tashar ABB S800 I / O, yana mai da shi kyakkyawan zaɓi don gina tsarin sarrafawa da aka rarraba a cikin Tsarin 800xA.
Sadarwar ModuleBus: Yana sadarwa tare da mai sarrafawa ta hanyar babban sauri, ModuleBus abin dogaro, yana ba da damar sarrafa fitarwa da sauri da amsa matsayi.
3. Bayanin Aiki da Ƙa'idar Aiki
Tsarin DO802 yana aiki azaman haɗin kai mai hankali tsakanin tsarin S800 I/O da manyan masu kunna wutar lantarki. Babban aikinsa shine canza siginar sarrafa dabaru na ƙananan matakin daga mai sarrafawa zuwa siginonin lantarki masu ƙarfi waɗanda ke iya tuƙi na'urorin filin kai tsaye.
Tsarin Cikin Gida:
Kowace tashar fitarwa tana samar da cikakkiyar siginar sigina, tana ƙunshe da abubuwa masu zuwa:
Optical Isolation Barrier: Provides electrical isolation between the control system side (logic side) and the field side (power side), preventing high voltage and noise from entering the sensitive control system.
Direba Relay: Yana karɓa kuma yana ƙara sigina daga na'urar gani da ido, yana samar da isasshiyar tuƙi don na'urar relay.
Relay Electromagnetic: The core switching element. Lokacin da coil ɗin ya sami kuzari, lambobinsa na al'ada Buɗe (NO) suna rufewa, suna haɗa kewayen kaya na waje. Lokacin da aka daina samun kuzari, lambobin sadarwa suna buɗewa ta ƙarfin bazara.
Ma'anar Matsayin Fitarwa (LED): An haɗa shi da da'ira, yana haskakawa lokacin da tashar ta kunna (fitarwa '1'), yana ba da ra'ayi na gani na gida.
Abubuwan Kariyar EMC: Yawanci sun haɗa da RC snubber circuits, varistors, ko freewheeling diodes, da dai sauransu. Waɗannan suna ɗaukar arcs ɗin da aka haifar yayin sauyawar lamba da kuma mayar da ƙarfin lantarki (EMF) daga lodin inductive, kare lambobin sadarwa da kuma hana tsangwama na lantarki.
Gudun Aiki:
Mai sarrafa tsarin yana aika umarnin fitarwa zuwa tsarin DO802 ta ModuleBus.
Ƙwararrun na'ura ta ciki tana aiwatar da umarni kuma tana watsa sigina ta hanyar na'urar gani da ido zuwa da'irar direban relay na tashar daidai.
Da'irar direba tana ƙarfafa coil ɗin relay, yana haifar da rufe lambobin sadarwa.
Load ɗin waje (misali, coil lamba, haske mai nuna alama) yana karɓar wuta daga samar da filin ta rufaffiyar lambobin sadarwa kuma yana aiki.
A lokaci guda, alamar matsayin tashar LED tana haskakawa.
ModuleBus yana ci gaba da saka idanu akan ƙarfin 24 V daga ModuleBus. Idan wannan ƙarfin ya zama maras kyau, tsarin nan da nan ya ba da rahoton kuskure ta hanyar ModuleBus kuma zai iya kunna aikin OSP bisa ga saitunan sa, yana sanya duk abubuwan da aka fitar zuwa cikin aminci bayan jinkiri.
4. Shigarwa da Haɗi
Haɗin Tsari:
DO802 yana amfani da hanyar haɗin kai mai sauƙi kuma madaidaiciya. An sanye da tsarin tare da mai haɗawa mai iya cirewa wanda ke nuna jimlar tashoshi 16 (tashoshi 8 x 2 tashoshi/tashar). Tashoshi biyu na kowane tashoshi ana yiwa lakabin 'xA' da 'xB' (inda x shine lambar tashar 1-8). Don fitarwar watsa shirye-shiryen Buɗewa (NO), yawanci haɗa gefe ɗaya na wadatar filin zuwa 'xA' da gefen kaya zuwa 'xB'. Ɗayan gefen nauyin yana haɗawa da baya zuwa wancan gefen samar da filin, yana kammala kewayawa.
Misalin Waya (Channel 1):
Tasha 1A: Haɗa zuwa gefen filin samar da filin 'tabbatacce' ko 'Layi (L)' (misali, 110V DC ko 250V AC).
Tasha 1B: Haɗa zuwa tasha ɗaya na na'urar lodi (misali, na'urar tuntuɓar mota).
Sauran tasha na na'urar lodi: Haɗa zuwa gefen 'negative' ko 'Neutral (N)' gefen samar da filin.
Bayanan shigarwa:
Koyaushe yi shigarwa da wayoyi tare da katse wutar lantarki.
Bi girman waya da buƙatun juzu'i da aka kayyade a cikin tebur da ke sama don tabbatar da amintaccen haɗin haɗin gwiwa.
Don kayan aikin inductive (misali, injuna, coils na relay), yana da mahimmanci don ƙara da'irori masu kariya (kamar daidaitattun diodes masu motsi ko RC snubbers) kamar yadda jagorar ko daidaitaccen aiki ya ba da shawarar don tsawaita rayuwar sadarwar.
Yi aiki da hanyar da ta dace ta hanyar keɓance igiyoyin wuta daga igiyoyin sigina don rage tsangwama.
