Hiki i ka AI895 Analog Input Module ke hoʻopili pololei i nā transmitters 2-wire a me kahi pilina pili hiki iā ia ke hoʻopili i nā transmitters 4-wire me ka nalowale ʻole o ka HART. ʻO ka AI895 Analog Input Module he 8 mau kaha. Aia ka module i nā ʻāpana palekana Intrinsic Safety ma kēlā me kēia kahawai no ka hoʻopili ʻana i nā mea 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 ʻana o ka volta hoʻokomo o ka hoʻokomo o kēia manawa he 3 V maʻamau, ua komo pū ʻo PTC. Hiki i ka mea hoʻolako transmitter no kēlā me kēia kahawai ke hāʻawi i ka liʻiliʻi o 15 V ma kahi 20 mA loop i kēia manawa i ka mana Ex i hōʻoia ʻia i nā transmitters a ua kaupalena ʻia i 23 mA i nā kūlana overload. Hiki ke hoʻohana ʻia ʻo TU890 a me TU891 Compact MTU me kēia module a hiki iā ia ke hoʻohui i ʻelua uea i nā mea hana me ka ʻole o nā mea hoʻopau. TU890 no nā noi Ex a me TU891 no nā noi ʻole Ex.
Nā hiʻohiʻona a me nā pono
• 8 kaha no 4...20 mA, hoʻokahi hoʻokomo unipolar.
• HART kamaʻilio.
• 1 pūʻulu o nā kaha 8 i hoʻokaʻawale ʻia mai ka lepo.
• Ka mana a me ka nānā 'ana no Ex i hōʻoia 'ia i elua-uwea transmitters.
• ʻAʻole mālama i ka ikehu hoʻokomo analog no nā kumu mana waho.
Nā MTU e pili ana i kēia huahana
