ABB AO815 3BSE052605R1 Analog Fitar Module

Module Fitar Analog na AO815 babban aiki ne, babban abin dogaro na masana'antu-samfurin fitarwa na siginar analog a cikin tsarin zaɓin kayan aikin ABB Ability™ System 800xA®. An tsara shi don sarrafa kansa na masana'antu da tsarin sarrafa tsari, wannan ƙirar tana ba da tashoshi na fitarwa na 8 masu zaman kansu na 4… 20 mA na yanzu kuma yana goyan bayan ka'idar sadarwar HART ta hanyar aiki. Ya dace da aikace-aikacen masana'antu daban-daban waɗanda ke buƙatar ingantaccen siginar siginar analog.

Tare da ƙirar ƙira, ƙirar AO815 tana ba da cikakkiyar ƙididdigar kai, keɓancewar wutar lantarki mai ƙarfi, da ƙarfin hana tsangwama. Ana amfani dashi sosai a cikin tsarin sarrafa sarrafa kansa a cikin masana'antu kamar mai da iskar gas, sinadarai, samar da wutar lantarki, ƙarfe, da jiyya na ruwa, yana ba da ikon sarrafa daidaitattun na'urorin filin kamar bawuloli, masu kunna wuta, da masu sarrafa mitar mitoci.

3. Ka'idar aiki da bincike

Tsarin AO815 yana fasalta haɗaɗɗen babban aikin CPU da keɓancewar fitarwa, tare da kowane tashoshi yana amfani da juzu'in dijital-zuwa-analog mai zaman kanta da raka'o'in tuƙi na yanzu. Module ɗin yana yin gwajin kai-da-kai, gami da:

• Kuskuren Tashoshin Waje: An bayar da rahoton lokacin da aikin samar da wutar lantarki ya yi ƙasa da ƙasa, ko lokacin da fitarwar halin yanzu ke ƙasa da ƙimar da aka saita kuma ƙimar saita shine> 1 mA (buɗaɗɗen kewaye).

• Kuskuren Tashoshin Ciki: An bayar da rahoton lokacin da kewayar fitarwa ba zai iya samar da daidaitaccen ƙimar halin yanzu ba.

• Kuskuren Module: Ya haɗa da kuskuren transistor mai fitarwa, gajeriyar kewayawa, kuskuren checksum, laifin samar da wutar lantarki na ciki, ƙarewar sa ido, da sauransu.

Fannin gaba na module ɗin sanye take da alamun matsayi na LED (F/R/W/O) mai wakiltar Laifi, Gudu, Gargaɗi, da Saitin Fitarwa azaman Jihohin da aka ƙaddara, yana sauƙaƙe saurin warware matsalar kan yanar gizo.
