ABB AO895 3BSC690087R1 Chithunzi cha Analogi
AO895 Analog Output Module ili ndi mayendedwe 8. Mutuwu umaphatikizapo zigawo za chitetezo cha Intrinsic Safety ndi mawonekedwe a HART pa njira iliyonse kuti agwirizane ndi kukonza zipangizo m'madera owopsa popanda kufunikira kwa zipangizo zina zakunja.
Chanelo chilichonse chimatha kuyendetsa mpaka 20 mA loop pakali pano ngati chosinthira cha Ex-certified current-to-pressure converter ndipo chimakhala ndi 22 mA podzaza. Makanema asanu ndi atatu onse ali olekanitsidwa ndi ModuleBus ndi magetsi mgulu limodzi. Mphamvu yopita kumagawo otulutsa imasinthidwa kuchokera ku 24 V pamalumikizidwe amagetsi.

Kutaya mphamvu 4.25 W
Zomwe zimagwiritsidwa ntchito pano + 5 V module basi 130 mA wamba
Kugwiritsa ntchito masiku ano +24 V kunja 250 mA wamba, <330 mA max
Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
-Kodi ntchito za module ya ABB AO895 ndi ziti?
Module ya ABB AO895 imapereka zizindikiro zotulutsa analogi zomwe zingagwiritsidwe ntchito kuwongolera ma actuators, ma drive othamanga, ndi zida zina zomwe zimafuna kuti ma siginecha a analogi agwire ntchito. Imatembenuza deta yamakina owongolera kukhala ma siginecha akuthupi omwe angagwiritsidwe ntchito kuwongolera machitidwe a zida zolumikizidwa.
-Kodi module ya AO895 ili ndi njira zingati zotulutsa?
Njira 8 zotulutsa analogi zimaperekedwa. Njira iliyonse imatha kupanga 4-20 mA kapena 0-10 V siginecha.
-Zomwe zili mu gawo la ABB AO895 ndi ziti?
Amapereka kuwongolera kolondola komanso magwiridwe antchito odalirika. Mitundu yotulutsa ma siginecha yosinthika imatha kukhazikitsidwa kuti ipereke ma siginecha apano (4-20 mA) kapena magetsi (0-10 V). Lili ndi mphamvu yodzifufuza kuti iwonetsetse thanzi la dongosolo ndikuzindikira mavuto. Zimaphatikizana ndi machitidwe a ABB 800xA kapena S800 I/O kudzera munjira zoyankhulirana monga Modbus kapena fieldbus.
