ABB AI895 3BSC690086R1 Analog Input Module
AI895 analog input module tuaj yeem txuas ncaj qha mus rau 2-xaim transmitters, thiab nrog cov kev sib txuas tshwj xeeb, nws tseem tuaj yeem txuas rau 4-xaim transmitters yam tsis poob HART functionality. AI895 analog input module muaj 8 raws. Lub module muaj xws li intrinsically muaj kev ruaj ntseg tiv thaiv Cheebtsam ntawm txhua channel rau kev sib txuas cov txheej txheem pab kiag li lawm nyob rau hauv tej qhov chaw txaus ntshai 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 rau cov tswv yim tam sim no feem ntau yog 3 V, suav nrog PTC. Lub transmitter fais fab mov rau txhua channel muaj peev xwm muab tsawg kawg 15 V ntawm 20 mA voj tam sim no rau lub zog Ex-certified txheej txheem transmitters, txwv rau 23 mA nyob rau hauv overload tej yam kev mob.

Cov lus nug nquag nug txog cov khoom yog raws li hauv qab no:
ABB AI895 3BSC690086R1 yog dab tsi?
ABB AI895 3BSC690086R1 yog ib qho analog input module uas belongs rau ABB's System 800xA series ntawm cov khoom. Nws yog tsuas yog siv los txais cov cim analog hauv cov tshuab automation thiab hloov lawv mus rau hauv cov teeb liab digital rau kev ua haujlwm ntxiv thiab kev tshuaj xyuas.
- Nws muaj pes tsawg lub tswv yim channel?
AI895 3BSC690086R1 muaj 8 qhov sib txawv input channel tshwj xeeb rau kev ntsuas thermocouple / mV.
- Nws qhov ntsuas qhov ntsuas yog dab tsi?
Txhua tus channel tuaj yeem teeb tsa los ntsuas hauv thaj tsam ntawm -30 mV rau +75 mV linear, lossis hom thermocouple sib raug.
-Dab tsi yog tus yam ntxwv ntawm nws txoj kev teeb tsa channel?
Ib qho ntawm cov channel (channel 8) tuaj yeem teeb tsa rau "txias kawg" (ambient) ntsuas kub, yog li nws tuaj yeem siv los ua CJ channel ntawm cov channel.
