ABB DO890 3BSC690074R1 Zotulutsa Zapa digito IS 4 Ch
Gawoli limaphatikizapo zigawo zachitetezo cha Intrinsic Safety panjira iliyonse kuti zilumikizidwe kukonza zida m'malo owopsa popanda kufunikira kwa zida zina zakunja.
Module ya DO890 imagwiritsidwa ntchito potulutsa ma siginecha owongolera digito ku zida zakunja zakumunda. Amapereka kudzipatula kwamagetsi pakati pa zida zam'munda ndi machitidwe owongolera, zomwe zimathandiza kuteteza dongosolo ku phokoso lamagetsi, kulakwitsa, kapena kuphulika kwa mafakitale.
Njira iliyonse imatha kuyendetsa mphamvu ya 40 mA kukhala 300-ohm field load monga Ex-certified solenoid valve, alarm sounder unit, kapena chizindikiro cha nyali. Kuzindikira kotseguka ndi kwakanthawi kochepa kumatha kukhazikitsidwa panjira iliyonse. Makanema anayi onsewa ali olekanitsidwa pakati pa mayendedwe ndi ModuleBus ndi magetsi. Mphamvu yopita kumagawo otulutsa imasinthidwa kuchokera ku 24 V pazolumikizira zamagetsi.
TU890 ndi TU891 Compact MTU itha kugwiritsidwa ntchito ndi gawoli ndipo imathandizira kulumikizana ndi mawaya awiri pazida zopangira popanda ma terminals owonjezera. TU890 ya ma Ex applications ndi TU891 yamapulogalamu omwe si Ex.
Gawoli lili ndi njira 4 zodziyimira pawokha za digito ndipo zimatha kuwongolera mpaka zida za 4 zakunja.
Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
- Ndi zida ziti zomwe zitha kuwongoleredwa pogwiritsa ntchito gawo la DO890?
Zida zosiyanasiyana za digito zomwe zimafuna chizindikiro choyatsa / kuzimitsa zimatha kuwongoleredwa, kuphatikiza ma relay, ma solenoid, ma mota, ma actuator, ndi ma valve.
- Kodi cholinga cha ntchito yodzipatula yamagetsi ndi chiyani?
Ntchito yodzipatula imalepheretsa zolakwika, phokoso lamagetsi, ndi kuphulika kwa zipangizo zam'munda kuti zisamakhudze dongosolo lolamulira, kuonetsetsa kuti zikugwira ntchito bwino m'madera ovuta.
- Kodi ndimakonza bwanji gawo la DO890?
Kukonzekera kumachitika kudzera mu S800 I/O System Configuration Tool, pomwe njira iliyonse imatha kukhazikitsidwa ndikuwunika momwe zimagwirira ntchito.
