ABB AI880A 3BSE039293R1 High Integrity Analoji yolowera gawo
AI880A High Integrity Analog Input Module idapangidwa kuti izingosintha kamodzi kokha komanso kochepera. Module ili ndi njira 8 zolowera pano. Kukana kolowera ndi 250 ohm.
Module imagawa ma transmitter akunja kunjira iliyonse. Izi zimawonjezera kulumikizana kosavuta kugawira zoperekera kwa 2- kapena 3-waya transmitters. Mphamvu ya transmitter imayang'aniridwa ndipo pano ndi yochepa. Makanema asanu ndi atatu onse adasiyanitsidwa ndi ModuleBus mugulu limodzi. Mphamvu ku Module imapangidwa kuchokera ku 24 V pa ModuleBus.
AI880A imagwirizana ndi malingaliro a NAMUR NE43, ndipo imathandizira kusinthika mopitirira ndi pansi pa malire.

Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
-Kodi ABB AI845 ndi chiyani?
ABB AI845 ndi gawo lolowera la analogi lomwe limasintha ma analogi kukhala ma data a digito omwe dongosolo lowongolera limatha kukonza. Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi masensa ndi zida zomwe zimapanga ma analogi, monga masensa kutentha (RTDs, thermocouples), ma transmitters, ndi zida zina zokhudzana ndi ndondomeko.
-Ndi mitundu yanji yazizindikiro zomwe gawo la AI845 lingagwire?
Zizindikiro zamakono (4-20 mA, 0-20 mA).
Mphamvu yamagetsi (0-10 V, ± 10 V, 0-5 V, etc.) zizindikiro
Resistance (RTDs, thermistors), mothandizidwa ndi mitundu ina monga 2, 3, kapena 4-waya RTDs
Thermocouples (ndi chipukuta misozi chozizira choyenera ndi mzere)
-Kodi zofunikira zamphamvu za AI845 ndi ziti?
AI845 imafuna magetsi a 24V DC kuti agwire ntchito.
