ABB AI895 3BSC690086R1 Analog Input Module
Hiki i ka AI895 analog input module ke hoʻopili pololei i nā transmitters 2-wire, a me nā pili kiko'ī, hiki iā ia ke hoʻopili i nā transmitters 4-wire me ka nalowale ʻole o ka hana HART. ʻO ka AI895 analog input module he 8 mau kaha. Aia i loko o ka module nā ʻāpana palekana palekana ma kēlā me kēia kahawai no ka hoʻopili ʻana i nā polokalamu kaʻina hana ma nā wahi pōʻino me ka ʻole o ka pono o nā mea ʻē aʻe o waho.
Hiki i kēlā me kēia kahawai ke mana a nānā i kahi transmitter kaʻina hana ʻelua a me ke kamaʻilio HART. ʻO ka hāʻule o ka volta hoʻokomo no ka hoʻokomo o kēia manawa he 3 V maʻamau, me ka PTC. Hiki i ka mana transmitter no kēlā me kēia kahawai ke hāʻawi i ka liʻiliʻi o 15 V ma 20 mA loop i kēia manawa i ka mana Ex-certified process transmitters, kaupalena ʻia i 23 mA i nā kūlana overload.
ʻikepili kikoʻī:
Hoʻoholo 12 bits
Hui kaawale i ka honua
Ma lalo o ka laulā 1.5 / 22 mA
Hapa 0.05% maʻamau, 0.1% kiʻekiʻe
ʻO ka neʻe ʻana o ka mahana he 100 ppm/°C maʻamau
Kānana hoʻokomo (manawa piʻi 0-90%) 20 ms
Ka palena o kēia manawa ʻO ka mana transmitter palena i kēia manawa
CMRR, 50Hz, 60Hz >80 dB
NMRR, 50Hz, 60Hz >10 dB
He 50 V ka puʻuwai hoʻokaʻawale i koho ʻia
Volta ho'āʻo dielectric 500 V AC
Hoʻopau mana 4.75 W
ʻO ka hoʻohana ʻana i kēia manawa +5 V module bus 130 mA maʻamau
Hoʻohana i kēia manawa +24 V waho 270 mA maʻamau, <370 mA kiʻekiʻe
ʻO nā nīnau i nīnau pinepine ʻia e pili ana i ka huahana penei:
-He aha ka ABB AI895 3BSC690086R1?
ʻO ka ABB AI895 3BSC690086R1 kahi module input analog nona ka ABB's System 800xA series of products. Hoʻohana nui ia no ka loaʻa ʻana o nā hōʻailona analog i nā ʻōnaehana automation a hoʻololi iā lākou i nā hōʻailona kikohoʻe no ka hana hou ʻana a me ka nānā ʻana.
-ʻEhia ka nui o nā ala komo?
Aia ka AI895 3BSC690086R1 he 8 mau ala komo ʻokoʻa i hoʻolaʻa ʻia no ke ana thermocouple/mV.
-He aha kona laulā ana?
Hiki ke hoʻonohonoho ʻia kēlā me kēia kahawai e ana ma kahi ākea o -30 mV a +75 mV linear, a i ʻole ke ʻano thermocouple pili.
-He aha nā hiʻohiʻona o kāna hoʻonohonoho ʻana i ke kahawai?
Hiki ke hoʻonohonoho ʻia kekahi o nā kahawai (channel 8) no ke ana wela "cold end" (ambient), no laila hiki ke hoʻohana ʻia ma ke ʻano he kahawai CJ o ke kahawai.
