2.1 Haɗin Hardware na Module
IS220PDIAH1B yana ɗaukar ƙira mai ƙima, da farko ya ƙunshi mahimman sassa uku:
BPPC Processor Board: Yana aiki a matsayin 'kwakwalwa', alhakin daidaita sadarwa tare da babban matakin sarrafawa, sarrafa bayanai, da sarrafa bincike. Idan aka kwatanta da wanda ya gabace ta, BPPC tana ba da ingantaccen ikon sarrafawa da ƙarin cikakken tallafin software (yana buƙatar ControlST* suite V04.04 ko kuma daga baya).
Hukumar Sayan Input Mai Hankali: Kayan aikin da aka keɓe don keɓancewar sigina, alhakin karɓar saƙon sigina daga hukumar tasha, aiwatar da canjin matakin, keɓewa, da tsarawa.
Mai Haɗi na DC-37-pin: Yana kan kasan tsarin, ana amfani da shi don haɗin haɗin kai tsaye zuwa allon shigarwar mai hankali, watsa siginar shigarwa 24, siginar gano ID, ikon nada, da umarnin amsawa da yawa.

3. Babban Ayyuka da Ka'idodin Aiki
3.1 Samun Siginar Tsare-tsare da Kwangila
Babban aikin IS220PDIAH1B shine samun daidai da dogaro da matsayi na busassun lambobin sadarwa guda 24. Gudun sarrafa siginar sa yana nuna ingantaccen ƙirar lantarki:
Yanayin Siginar Mataki Biyu:
Sharadi na Farko akan Hukumar Tasha: Tashar tashar tana ba da wutar lantarki mai jika (yana goyan bayan 24V DC, 48V DC, ko 125V DC) kuma yana amfani da shi ga lambar sadarwa ta filin ta hanyar resistor mai iyakancewa. Lokacin da lambar ke rufewa, ana yin madauki, yana samar da shigar yanzu.
Yanayin Sakandare a Module na I/O: Hukumar saye tana karɓar siginar wutar lantarki daga hukumar tasha kuma tana yin ƙarin kwandishan, gami da tacewa da canjin matakin, don dacewa da daidaitattun matakan fitarwa na na'ura.
Keɓewar gani: Kowane tashar shigarwa ta keɓe ta hanyar lantarki daga dabarun sarrafawa ta hanyar opto-coupler, wanda aka ƙididdige 1500V. Wannan yana hana tsangwama sosai kamar hawan wutar lantarki da bambance-bambance masu yuwuwar ƙasa daga gefen filin shiga ɓangaren tsarin sarrafawa, yana haɓaka haɓakar amo da amincin tsarin. Yana da mahimmanci a lura cewa tashoshin shigarwar 24 ba su keɓance da juna ba.
3.2 Variable Threshold Detection and Intelligent Diagnostics
This is a key technology employed by the IS220PDIAH1B to ensure input accuracy:
Dynamic Threshold Calculation: The comparator threshold for input detection is not fixed but is derived from the contact wetting voltage input from the terminal board. A mafi yawan aikace-aikace, wannan ƙarfin lantarki yana da ma'auni don samar da iyakar gano shigarwar kashi 50%. Misali, tare da wutar lantarki 125V DC, madaidaicin kusan 62.5V.
Kariyar Ƙarƙashin Ƙofa: Don hana yanayin shigarwa mara iyaka idan wutar lantarki ta faɗi zuwa sifili, ana manne bakin kofa zuwa mafi ƙarancin 13%.
Undervoltage Detection: If the contact wetting voltage falls below 40% of the nominal voltage, an undervoltage detector annunciates this condition to the control system, indicating unreliable signal quality.
Yanayin Gwajin Pulse: Tsarin yana aiwatar da gwajin ganowa ta atomatik kowane sakan 4. A cikin wannan yanayin, ana bugun bakin kofa da karfi da karfi sannan kuma a kasa, kuma tsarin yana duba martanin na'urorin gani. Duk tashar shigarwar da ta kasa amsa daidai ga wannan bugun gwajin ana yi mata alama a matsayin kuskure kuma yana haifar da ƙararrawa. Wannan tsarin yana gano yuwuwar al'amura kamar tsufa na optocoupler, buɗaɗɗen da'irori, ko kurakuran wayoyi na waje.
3.3 Tace shigarwar da Alamar Matsayi
Tace Hardware: Kowace tashar shigarwa tana sanye take da matatar kayan aiki na milli daƙiƙa 4, yadda ya kamata yana danne glitches na wucin gadi wanda ya haifar ta hanyar billa lamba ko tsangwama na lantarki, yana tabbatar da ingantaccen karatun matsayi.
Ƙimar Wutar Lantarki na AC: Tare da 125V DC wetting, ƙirar tana da ikon ƙin yarda da yanayin gama-gari na 60V RMS (50/60Hz), yana ba da damar ingantaccen siginar DC a cikin mahalli tare da tsangwama na AC.
Nunin Matsayin Filin: Module na gaba yana fasalta alamar rawaya matsayi na LED don kowane tashoshi na shigarwa 24. Lokacin da shigarwar ta sami kuzari (rufe lamba, sigina yana aiki), LED ɗin daidai yake haskakawa; lokacin da shigar da aka kashe kuzari (bude lamba), LED yana kashewa. Wannan yana ba wa ma'aikatan kulawa da ilhama ta hanyar tantance matsayi yayin gyara da kiyayewa.
