Chithunzi cha ABB AI895 3BSC690086R1
AI895 gawo lolowera la analogi limatha kulumikizana mwachindunji ndi ma transmitters a 2-waya, ndipo ndi maulumikizidwe apadera, imatha kulumikizananso ndi ma transmitter 4 popanda kutaya magwiridwe antchito a HART. AI895 analogi gawo lolowera lili ndi 8 njira. Gawoli limaphatikizapo zida zotetezera zotetezedwa panjira iliyonse yolumikizira zida zamakina m'malo owopsa popanda kufunikira kwa zida zina zakunja.
Njira iliyonse imatha mphamvu ndikuwunika njira yotumizira mawaya awiri ndi kulumikizana kwa HART. Kutsika kwamagetsi komwe kumalowetsapo nthawi zambiri kumakhala 3 V, kuphatikiza PTC. Magetsi opatsira panjira iliyonse amatha kupereka osachepera 15 V pa 20 mA loop pakali pano kuti azitha kugwiritsa ntchito ma transmitters ovomerezeka a Ex-certified, ochepera 23 mA m'malo odzaza.

Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
-Kodi ABB AI895 3BSC690086R1 ndi chiyani?
ABB AI895 3BSC690086R1 ndi gawo lolowera la analogi lomwe ndi la ABB's System 800xA mndandanda wazogulitsa. Amagwiritsidwa ntchito kwambiri polandila ma analogi m'makina opangira makina ndikuwasintha kukhala ma siginecha a digito kuti apitilize kusanthula ndi kusanthula.
-Ili ndi ma tchanelo angati olowera?
AI895 3BSC690086R1 ili ndi njira 8 zolowera zosiyana zoperekedwa ku muyeso wa thermocouple/mV.
-Kodi miyeso yake ndi yotani?
Njira iliyonse imatha kukonzedwa kuti imayeza mumitundu yosiyanasiyana -30 mV mpaka +75 mV liniya, kapena mtundu wofananira wa thermocouple.
-Kodi mawonekedwe ake ndi chiyani?
Imodzi mwa njira (channel 8) ikhoza kukhazikitsidwa kuti ikhale yoyezera kutentha kwa "cold end" (yozungulira), kotero ingagwiritsidwe ntchito ngati njira ya CJ ya tchanelo.
