II. Babban Ayyuka

Babban ayyuka na IS200EXHSG3A sun haɗa da, amma ba'a iyakance su ba, masu zuwa:

1. 41 DC Contactor Drive

IS200EXHSG3A yana ba da direbobi masu lamba 41 DC guda biyu (K41A, K41B), wanda direbobi ke sarrafawa akan EMIO. Direba a kan EMIO yana buƙatar duka umarni daga Filin Shirye-shiryen Ƙofar Ƙofar (FPGA) da lambar sadarwar 86G kafin a ƙarfafa direban. Ko dai FPGA ko lambar sadarwar 86G na iya sa direban ya daina kuzari.

A cikin tsarin sarrafawa da yawa (G3), abubuwan shiga daga M1, M2, da masu kula da C suna sarrafa relays guda uku da aka haɗa a cikin da'irar zaɓe na 2-fita-3. Ana amfani da coil na relay ta 24V dc daga M1 da M2.

Ba kamar nau'ikan G1 da G2 ba, sigar G3 ta tsallake da'irar mai gudanarwa na yanzu. Direba yana ba da wutar lantarki ta 125V akai-akai (P125) zuwa nada, maimakon haɓakar ƙarfin wutan lantarki wanda ke biye da yanayin riƙon yau da kullun.

Siginonin matsayi na de-excitation sun samo asali ne daga hukumar EDEX, an tsara su a kan EXHS, kuma ana aika su zuwa EMIO-M1 da EMIO-M2 (don sarrafawa mai yawa).

4. Kula da Shigar da Tuntuɓi

Hukumar IS200EXHSG3A tana kawo lambobin taimako don 53A, 53B, da 41 don saka idanu ta EMIO. A cikin ƙarin sarrafawa, ana watsa siginar zuwa masu kula da M1, M2, da C. An jika lambobin sadarwa guda uku ta 70 V dc da aka kawo daga EXHS. Wutar lantarki daga matosai J12M1 da J12M2 an ware resistor kuma ana bayarwa ga lambobin sadarwa. Wetting ƙarfin lantarki iya bambanta daga 63 zuwa 84 V dc. Sakamakon sigina yana nuna fan zuwa M1, M2, da C. Da'irar saka idanu na lamba yana kan EMIO.

5. Shigar da Matsayin Crowbar

Ana ba da siginar matsayin Crowbar daga allunan EDEX guda biyu zuwa EMIO-M1 da EMIO-M2 ta hanyar EXHS. Da'irar kwandishan akan EXHS tana lura da abubuwan da aka shigar daga allunan EDEX. Idan ko wanne ya canza zuwa ƙananan impedance (gudanar crowbar), yana aika sigina zuwa EMIO a cikin M1.

6. Sigina Conditioning Circuits

A cikin sarrafawa mai yawa, ana ba da siginar cirewa daga allunan EDEX guda biyu zuwa EMIO-M1 da EMIO-M2 ta hanyar EXHS. Akwai da'irori na sigina guda biyu akan EXHS, ɗaya don kowane sigina. EXHS yana maimaita siginar zuwa EMIO.
