ABB AI895 3BSC690086R1 Imodyuli yoNgeniso yeAnalog
Imodyuli ye-AI895 ye-analog input ingakwazi ukudibanisa ngokuthe ngqo kwii-2-wire transmitters, kunye nokudibanisa okuthe ngqo, inokuphinda idibanise kwi-4-wire transmitter ngaphandle kokulahlekelwa ukusebenza kwe-HART. Imodyuli ye-analog ye-AI895 ineendlela ezi-8. Imodyuli ibandakanya amacandelo okhuseleko angaphakathi kwitshaneli nganye yokudibanisa izixhobo zenkqubo kwiindawo ezinobungozi ngaphandle kwesidingo sezixhobo ezongezelelweyo zangaphandle.
Ijelo ngalinye linokunika amandla kunye nokubeka iliso kwi-transmitter yenkqubo yeentambo ezimbini kunye nonxibelelwano lwe-HART. Ukuhla kwamandla ombane kwigalelo langoku ngokuqhelekileyo yi-3 V, kuquka i-PTC. Unikezelo lwamandla othungelwano lwejelo ngalinye luyakwazi ukubonelela ubuncinci be-15 V kwi-20 mA loop yangoku kumandla othumelo lwenkqubo eqinisekisiweyo yangaphambili, ekhawulelwe kwi-23 mA kwiimeko zokugcwala.
Idatha eneenkcukacha:
Isisombululo 12 bits
Ukwahlula Iqela ukuya emhlabeni
Ngaphantsi / ngaphezulu koluhlu lwe-1.5 / 22 mA
Imposiso 0.05% eqhelekileyo, 0.1% ubuninzi

Isihluzi segalelo (ixesha lokunyuka 0-90%) 20 ms
Umda wangoku Uthungelwano lwangoku olwakhelwe ngaphakathi olunciphisa amandla othumeli
CMRR, 50Hz, 60Hz>80 dB
NMRR, 50Hz, 60Hz >10 dB
I-voltage elinganisiweyo ye-insulation 50 V
Umbane wovavanyo lwe-Dielectric 500 V AC
Ukutshatyalaliswa kwamandla 4.75 W
Ukusetyenziswa kwangoku +5 V ibhasi yemodyuli 130 mA eqhelekileyo
Ukusetyenziswa kwangoku +24 V yangaphandle 270 mA eqhelekileyo, <370 mA ubuninzi
Imibuzo edla ngokubuzwa malunga nemveliso yile ilandelayo:
-Yintoni i-ABB AI895 3BSC690086R1?
I-ABB AI895 3BSC690086R1 yimodyuli yokufaka i-analog eyeye-ABB's System 800xA uluhlu lweemveliso. Isetyenziselwa kakhulu ukufumana imiqondiso ye-analog kwiinkqubo ezizenzekelayo kwaye iguqulelwe kwiimpawu zedijithali ukwenzela ukuqhubeka nokuhlalutya.
-Zingaphi iitshaneli zongeniso enazo?
I-AI895 3BSC690086R1 ineendlela ezisi-8 ezihlukeneyo ezinikezelwe kumlinganiselo we-thermocouple/mV.
-Luthini uluhlu lwayo lomlinganiselo?
Ishaneli nganye inokumiselwa ukuba ilinganise kuluhlu lwe--30 mV ukuya ku-+75 mV umgca, okanye uhlobo oluhambelanayo lwe-thermocouple.
-Ziziphi iimpawu zoqwalaselo lwetshaneli yayo?
Enye itshaneli (itshaneli yesi-8) inokuqwalaselwa "isiphelo esibandayo" (i-ambient) yokulinganisa ubushushu, ngoko inokusetyenziswa njengejelo le-CJ letshaneli.
