imikhiqizo

4 kuya ku-20 mA umthombo. Isiteshi ngasinye esiphumayo sishayela umthwalo wangaphandle futhi sikhiqiza okukhiphayo okungu-0 kuye ku-20 mA. Amandla okudlulisa ukusuka kumojula ngayinye ayi-diode NOMA ahlanganiswe ndawonye ku-adaptha engasasebenzi ukuze kuqinisekiswe amandla angasebenzi. I-microprocessor yemojuli ngayinye isebenzisa uhlelo lokusebenza lwe-analog I/O, kanye nezinqubo zokuphepha eziqinisekisa impilo ye-FBM. Izinketho zeshaneli yokokufaka zihlanganisa ukukhetha okulungisekayo kwesikhathi sokuhlanganisa ngesisekelo semojuli ngayinye. Ukuvikeleka kwesiteshi okokufaka kuthuthukiswa ngokunika amandla kabusha iluphu yamanje yokokufaka kusukela kumandla kagesi wesiteshi ngasinye kumojuli ngayinye yokubhangqa. Izinketho ezilungisekayo kumamojula okuphepha okukhiphayo zifaka Isenzo Sokuhluleka-Ukuphepha (Ukubamba/Ukubuyela emuva), Idatha Yokuphuma Kwe-Analogi Yehlulekile-Ukuphepha Okuphephile (ngesisekelo sesiteshi ngasinye), I-Fieldbus I-Fail-Safe Enable, kanye Nesikhathi Sokubambezeleka Kwe-Fieldbus. Inketho ye-Analog Output Fail-Safe Fallback Data kufanele isethelwe okukhiphayo okungu-0 mA. Lokhu kususa elinye lamashaneli aphumayo angasasebenzi enkonzweni ngezinkinga ezibonakala njengemojula engakutholi kahle okukhiphayo okubhaliwe noma ukungaphumeleli ukuhlolwa kokuvikela ku-FBM microprocessor ebhalela kumarejista okukhiphayo. Ukusethwa kwenketho ye-Analog Output Fail-Safe Fallback Data yokukhipha okungu-0 mA nakho kunciphisa amathuba okuba nomphumela "wokufeyila phezulu". UKUNEMBA OKUPHEZULU Ukuze uthole ukunemba okuphezulu, imojula ihlanganisa iziguquli ze-sigmadelta zesiteshi ngasinye, esihlinzeka ngokufundwa kokufakwayo okusha kwe-analog njalo ngama-25 ms, kanye nesikhathi esilungisekayo sokuhlanganisa ukuze kususwe noma yimuphi umsindo wenqubo namaza wezintambo zamandla. Isikhathi ngasinye, i-FBM iguqulela okokufaka kwe-analog ngakunye kube ivelu yedijithali, ilinganisela lawa manani phakathi nenkathi ethile futhi inikeze inani elilinganiselwe kusilawuli. UKWETHEMBEKA OKUPHEZULU Ukuphinda kuphindwe kabili kwemojula, kuhlanganiswe nokumbozwa okuphezulu kwamaphutha, kunikeza isikhathi esiphezulu kakhulu sokutholakala kwesistimu engaphansi. I-Redundant Adapter ihlinzeka ngamaphoyinti okuhlola angasetshenziselwa ukuhlola ngezikhathi ezithile kanye nokukalwa kwe-voltage ephumayo yesidluliseli samandla ngasinye. Ukuhlola njalo ngezikhathi ezithile kungakhuphula ukutholakala kwezibalo zemojuli. I-Standard DESIGN FBM205 ine-aluminium yangaphandle emangelengele ukuze ivikeleke ngokomzimba amasekhethi. Izivalo eziklanyelwe ukukhwezwa ama-FBM zihlinzeka ngamazinga ahlukahlukene okuvikelwa kwemvelo, kuze kufike ezindaweni ezinokhahlo, ngokwe-ISA Standard S71.04. IZIKHOMBISI EZIBONAKALAYO Ama-diode akhipha ukukhanya (Ama-LED) afakwe ngaphambili kwemojuli ahlinzeka ngezinkomba zesimo sokubukwayo semisebenzi yeMojuli ye-Fieldbus. UKUSUSA/UKUBUYISELWA OKULULA Noma iyiphi imojuli ingase ishintshwe ngaphandle kokuphazamisa okokufaka kwenkambu noma amasignali okukhiphayo kumojula enhle. Imojuli ingasuswa/ishintshwe ngaphandle kokukhipha ikhebula yokunqanyulwa kwensimu yensimu, amandla, noma ikhebula yezokuxhumana. UKUXHUMANA KWA-FIELDBUS Imojuli Yezokuxhumana ye-Fieldbus noma i-Control Processor ixhuma kumojula engasadingeki ongu-2 Mbps i-Fieldbus esetshenziswa ama-FBM. I-FBM205 yamukela ukuxhumana okuvela kunoma iyiphi indlela (A noma B) ye-2 Mbps Fieldbus — uma umzila owodwa wehluleka noma ushintshwa ezingeni lesistimu, imojuli iqhubeka nokuxhumana endleleni esebenzayo.
