I-ABB AI895 3BSC690086R1 Imojuli yokufaka ye-Analog
Imojula yokufaka ye-analog ye-AI895 ingaxhumeka ngokuqondile kuma-2-wire transmitter, futhi ngoxhumo oluthile, ingaphinda ixhume kuma-4-wire transmitter ngaphandle kokulahlekelwa ukusebenza kwe-HART. Imojuli yokufaka ye-analog ye-AI895 ineziteshi eziyi-8. Imojula ihlanganisa izingxenye ezivikelekile zangaphakathi ezivikelekile esiteshini ngasinye sokuxhuma imishini yenqubo ezindaweni eziyingozi ngaphandle kwesidingo semishini yangaphandle eyengeziwe.
Isiteshi ngasinye singanika amandla futhi sigade isidlulisi senqubo esinezintambo ezimbili kanye nokuxhumana kwe-HART. Ukwehla kwamandla kagesi okokufaka kwamanje ngokuvamile kungu-3 V, okuhlanganisa ne-PTC. Ukunikezwa kwamandla kagesi wesiteshi ngasinye kukwazi ukunikeza okungenani i-15 V ku-20 mA loop yamanje ukuze inike amandla ama-Transmitter ezinqubo eziqinisekisiwe, anqunyelwe ku-23 mA ezimeni zokugcwala ngokweqile.
Idatha enemininingwane:
Ukulungiswa 12 bits
Ukuzihlukanisa Iqembu phansi
Ngaphansi/ngaphezulu kwebanga 1.5 / 22 mA
Iphutha elingu-0.05% elijwayelekile, umkhawulo ongu-0.1%.
Ithempelesha yokushayela engu-100 ppm/°C evamile
Isihlungi sokufaka (isikhathi sokukhuphuka 0-90%) 20 ms
Umkhawulo wamanje Amandla esithumeli esikhawulelayo eyakhelwe ngaphakathi
I-CMRR, 50Hz, 60Hz >80 dB
I-NMRR, 50Hz, 60Hz >10 dB
Isilinganiso se-voltage ye-insulation 50 V
I-Dielectric test voltage 500 V AC
Ukuchithwa kwamandla 4.75 W
Ukusetshenziswa kwamanje +5 V module ibhasi 130 mA ejwayelekile
Ukusetshenziswa kwamanje +24 V kwangaphandle okungu-270 mA okujwayelekile, <370 mA umkhawulo
Imibuzo evame ukubuzwa ngomkhiqizo imi kanje:
-Iyini i-ABB AI895 3BSC690086R1?
I-ABB AI895 3BSC690086R1 iyimojula yokufaka ye-analog eyingxenye yochungechunge lwemikhiqizo ye-ABB's System 800xA. Isetshenziswa kakhulu ukuthola amasiginali e-analog ezinhlelweni ezizenzakalelayo futhi iguqulelwe kumasiginali wedijithali ukuze kuqhutshekwe nokucubungula nokuhlaziya.
-Mangaki amashaneli okufakwayo enawo?
I-AI895 3BSC690086R1 ineziteshi zokufaka ezihlukene ezingu-8 ezinikezelwe esilinganisweni se-thermocouple/mV.
-Liyini ibanga layo lokulinganisa?
Isiteshi ngasinye singalungiselelwa ukuthi silinganise ku--30 mV kuya ku-+75 mV eqondile, noma uhlobo oluhambisanayo lwe-thermocouple.
-Iziphi izici zokucushwa kwesiteshi sayo?
Esinye seziteshi (isiteshi 8) singalungiselelwa ukukala izinga lokushisa "elibandayo" (ama-ambient), ngakho singasetshenziswa njengesiteshi se-CJ sesiteshi.
