AI895 Analog Input Module tuaj yeem cuam tshuam ncaj qha 2-xaim transmitters thiab nrog rau kev sib txuas tshwj xeeb nws tuaj yeem cuam tshuam 4-xaim transmitters yam tsis tau poob lub peev xwm HART.AI895 Analog Input Module muaj 8 raws.Lub module muaj xws li Intrinsic Safety tiv thaiv Cheebtsam ntawm txhua channel rau kev sib txuas rau cov txheej txheem cov cuab yeej nyob rau hauv tej yam kev puas tsuaj yam tsis tas yuav tsum tau ntxiv rau lwm yam khoom siv.Txhua tus channel tuaj yeem siv hluav taws xob thiab saib xyuas ob-xaim txheej txheem transmitter thiab HART kev sib txuas lus.Lub input voltage poob ntawm cov tswv yim tam sim no feem ntau yog 3 V, PTC suav nrog.Lub transmitter mov rau txhua channel muaj peev xwm muab tau yam tsawg kawg yog 15 V ntawm ib tug 20 mA voj tam sim no rau lub hwj chim Ex certified txheej txheem transmitters thiab yog txwv rau 23 mA nyob rau hauv overload tej yam kev mob. TU890 thiab TU891 Compact MTU tuaj yeem siv nrog cov qauv no thiab nws ua rau ob lub xaim txuas rau cov txheej txheem cov khoom siv yam tsis muaj qhov txuas ntxiv.TU890 rau Ex daim ntawv thov thiab TU891 rau cov ntawv tsis yog Ex.
Nta thiab cov txiaj ntsig
• 8 raws rau 4...20 mA, ib qho kawg unipolar inputs.
• HART kev sib txuas lus.
• 1 pawg ntawm 8 channel cais tawm hauv av.
• Fais fab thiab saib xyuas rau Ex certified ob-xaim transmitters.
• Tsis siv hluav taws xob khaws cov analog inputs rau cov khoom siv hluav taws xob sab nraud.
