Zithunzi za ABB DI821 3BSE008550R1 Digital Input module
DI821 ndi 8 channel, 230 V ac/dc, digital input module ya S800 I/O. Gawoli lili ndi zolowetsa za digito 8. Mphamvu yamagetsi ya AC ndi 164 mpaka 264 V ndipo zolowetsa panopa ndi 11 mA pa 230 V ac The dc input voltage range ndi 175 mpaka 275 volt ndipo panopa ndi 1.6 mA pa 220 V dc Zolowetsazo zimakhala payekha.
Njira iliyonse yolowera imakhala ndi zoletsa zomwe zikuchitika, zida zotetezera za EMC, LED yolowera, chotchinga chodzipatula komanso chosefera cha analogi (6 ms).
Channel 1 ingagwiritsidwe ntchito ngati magetsi oyang'anira njira 2 - 4, ndipo njira 8 ingagwiritsidwe ntchito ngati magetsi oyang'anira njira 5 - 7. Ngati magetsi olumikizidwa ndi tchanelo 1 kapena 8 atha, zolowetsa zolakwika zimatsegulidwa ndipo Chenjezo. LED imayatsa. Chizindikiro cholakwika chikhoza kuwerengedwa kuchokera ku ModuleBus.

Mafunso omwe amafunsidwa pafupipafupi pazamalonda ndi awa:
-Kodi ABB DI821 ndi chiyani?
Module ya DI821 ikugwira ma sign a digito (binary) kuchokera kuzipangizo zam'munda. Imatembenuza zizindikiro izi kukhala deta yomwe dongosolo lolamulira lingathe kuchita.
-Ndi njira zingati zomwe DI821 imathandizira?
Gawo la DI821 limathandizira njira 8 zolowera digito, iliyonse yomwe imatha kulandira ma siginecha a binary
-Ndi mitundu yanji yazizindikiro zomwe gawo la DI821 lingagwire?
Module ya DI821 imatha kuthana ndi zolowetsa zowuma ngati zolumikizirana ndi zolumikizira zonyowa ngati ma siginecha a 24V DC. Nthawi zambiri amagwiritsidwa ntchito pazida zomwe zimatulutsa ma siginecha osiyanasiyana, monga masiwichi owuma, masensa oyandikira, masiwichi ochepera, mabatani, zolumikizirana.
