Bayanin Aiki

IS200EGDMH1AAB shine ainihin sashin aikin gano ƙasa a cikin tsarin sarrafa tashin hankali na EX2100. Babban manufarsa shine ganowa da auna juriya tsakanin kewaye filin janareta da ƙasa. Ƙananan juriya yana nuna kuskuren ƙasa, wanda zai iya haifar da mummunar lalacewa idan ba a magance shi da sauri ba.

A cikin tsarin da aka sake maimaitawa, ana saita nau'ikan EGDM guda uku azaman Mai sarrafawa (C) , Jagora 1 (M1) , da Jagora 2 (M2) . Tsarin kowane EGDM ana sarrafa shi ta saitin fil ɗin shirin akan mai haɗin P2. Kwamitin DSPX (Digital Signal Processor) a cikin rakiyar mai sarrafawa yana ƙayyade wane maigidan ne ke ba da siginar tuƙi zuwa mai jujjuya hankali a cikin EXAM attenuator module. Ana aika wannan bayanin ta hanyar EISB (Exciter Internal Serial Bus) zuwa tsarin C ta hanyar haɗin fiber-optic. Bayan karɓar wannan bayanin, tsarin C ko dai yana ba da ikon relay a cikin tsarin EXAM (idan M2 direba ne) ko kuma ya bar shi mara ƙarfi (idan M1 shine babban zaɓaɓɓen). A lokaci guda, ana aika sigina na banbanta zuwa M1 da M2 yana nuna maigidan da aka zaɓa, yana ba da damar janareta na siginar akan mai aiki da zaɓin tushen umarnin gwaji akan kowane module.

Maigidan mai aiki yana karɓar siginar oscillator daga DSPX akan hanyar haɗin fiber-optic, wanda yake jujjuya shi zuwa madaidaicin raƙuman murabba'in 50-volt mara kyau. Ana aika wannan ƙarfin lantarki ta hanyar kebul zuwa ƙirar EXAM kuma ana amfani da ita zuwa ƙarshen ma'aunin ma'ana. Sakamakon faɗuwar wutar lantarki a kan ma'aunin ma'ana ya yi daidai da juriyar kewaye filin filin.

VCO tana sarrafa mai watsa fiber-optic wanda ke aika sigina zuwa tsarin sarrafawa don sarrafawa.

IS200EGDMH1AAB kuma ya haɗa da fasalin gwaji. Na'urar sanyaya sigina na iya auna matakin fitarwa na amplifier ta hanyar saukar da gefen gada na mai jujjuya hankali akan umarni daga sashin sarrafawa. Hakanan tsarin C yana haifar da umarnin gwaji a kowane canji na siginar oscillator, wanda ke samar da siginar gwaji na 250 ms akan kowane nau'in (wanda ba za'a iya dawo da shi ba) don tabbatar da aikin da ya dace.

Samar da Wutar Lantarki da Ƙarfafa Sigina

Sashin samar da wutar lantarki na IS200EGDMH1AAB yana karɓar 24 V dc daga EPSM (Exciter Power Supply Module) da ya dace ta hanyar jirgin baya na EPBP. Yin amfani da mai canza DC-DC, yana haifar da:

• ± 65 V dc (wanda ba a keɓe ba) don amplifier mai ƙarfi a cikin sashin janareta na sigina.

• +5 V dc (keɓe) don dabaru.

• ± 15 V dc (keɓe) don sigina kwandishan.

Fitowar amplifier wutar lantarki tushen ƙarfin lantarki ne tare da abin fitarwa ƙasa da 1.0 ohm. Yana samar da raƙuman murabba'in ± 50 V tare da iyaka na yanzu na kusan 80mA. A lokacin aiki na al'ada, lokacin shine 5 seconds; yayin aikin gwaji, lokacin yana rage zuwa 400 ms.
