Product Overview

I-Trusted® TMR 24 Vdc Digital Output Module ijongana nezixhobo zentsimi ezingama-40. Iimvavanyo zokuxilonga eziphindwe kathathu zenziwa kuyo yonke iModyuli kubandakanywa imilinganiselo yangoku, kunye ne-voltage kwisahlulo ngasinye setshaneli ephumayo evotelweyo. Iimvavanyo zikwasetyenziselwa ukungaphumeleli kunye nokuxinga. Ukunyamezela impazamo kuphunyezwa ngoyilo lwe-Triple Modular Redundant (TMR) ngaphakathi kweModyuli nganye yeetshaneli zemveliso ezingama-40. Ukubekwa esweni komgca ozenzekelayo wesixhobo sommandla unikiwe. Eli nqaku lenza ukuba iModyuli ibone zombini iintsilelo ezivulekileyo nezimfutshane kwi-wiring yentsimi kunye nezixhobo zokulayisha. IModyuli ibonelela ngokulandelelana kweziganeko (SOE) ebhodini ngesisombululo se-1 ms. Utshintsho lwemveliso yelizwe lubangela ukungena kwe-SOE. Iimeko zemveliso zimiselwa ngokuzenzekelayo ngamandla ombane kunye nemilinganiselo yangoku ebhodini kwiModyuli. Le Modyuli ayivunywanga uqhagamshelo oluthe ngqo kwiindawo ezinobungozi kwaye kufuneka isetyenziswe ngokudityaniswa nezixhobo ze-Intrinsic Safety Barrier.

Iqela ngalinye elinjalo liQela laMandla (PG).

Imodyuli ye-TMR 24 Vdc yeZiphumo zeDijithali lilungu loluhlu oluThenjiweyo lweeModyuli zeNgeniso/Isiphumo (I/O). Zonke iiModyuli ezithembekileyo ze-I/O zabelana ngokusebenza okufanayo kunye nefom. Kwinqanaba eliqhelekileyo, zonke iiModyuli ze-I / O zijongana ne-Inter-Module Bus (IMB) enika amandla kwaye ivumela unxibelelwano kunye ne-TMR Processor. Ukongeza, zonke iiModyuli zinojongano lwasendle olusetyenziselwa ukuqhagamshela kwiimpawu ezithile zeModyuli entsimini. Zonke iiModyuli ziyi-Triple Modular Redundant (TMR).

1.1.IYunithi yokuTyelwa kweNdawo (FTU)

I-Field Termination Unit (FTU) licandelo le-I/O Module edibanisa zonke ii-FIU ezintathu kwi-interface yentsimi enye. I-FTU ibonelela ngeQela lokuShintsha ngokuKhuselekileyo kunye neenxalenye ze-passive eziyimfuneko kwimo yesignali, ukukhuselwa kwe-voltage ngaphezulu, kunye nokucoca i-EMI/RFI. Xa ifakwe kwi-Trusted Controller okanye i-Expander Chassis, i-FTU isidibanisi sentsimi sidibanisa kwiNdibano ye-Cable ye-Field I / O eqhotyoshelwe ngasemva kwe-Chassis. Ikhonkco le-SmartSlot ligqithiselwe kwi-HIU ukuya kuqhagamshelwano lwentsimi nge-FTU. Ezi zibonakaliso zihamba ngokuthe ngqo kwidibansi yentsimi kwaye zigcine ukuzihlukanisa kwiimpawu ze-I / O kwi-FTU. Ikhonkco le-SmartSlot lunxibelelwano olukrelekrele phakathi kweeModyuli eziSebenzayo kunye nezokulinda ulungelelwaniso ngexesha lokutshintshwa kweModyuli.

1.2.IYunithi yoNxibelelwano lweNdawo (FIU)

I-Field Interface Unit (FIU) licandelo leModyuli equlathe iisekethe ezithile eziyimfuneko ukujongana neentlobo ezithile zeempawu ze-I/O zentsimi. Imodyuli nganye ineFIUs ezintathu, enye ngesilayi. Kwimodyuli ye-TMR 24 Vdc Digital Output, i-FIU iqulethe inqanaba elilodwa le-output switch structure, kunye ne-sigma-delta (ΣΔ) yesiphaluka semveliso nganye kwimveliso ye-40 yentsimi. Iisekethe ezimbini ezongezelelweyo ze-ΣΔ zibonelela ngokujongwa okukhethiweyo kwintsimi yangaphandle ye-I/O yombane wokubonelela.

I-FIU ifumana amandla angawodwa kwi-HIU ngengqiqo. I-FIU ibonelela ngemeko yombane eyongezelelweyo kwimibhobho yokusebenza efunwa yi-FIU circuitry. Ikhonkco elizimeleyo le-6.25 Mbit/sec lidibanisa i-FIU nganye kwenye yezilayi ze-HIU. I-FIU iphinda ilinganise uluhlu lweempawu "zokugcinwa kwendlu" ebhodini ezincedisa ukubeka esweni ukusebenza kunye neemeko zokusebenza zeModyuli. Le miqondiso ibandakanya amandla ombane ombane, ukusetyenziswa kwangoku, umbane wesalathiso osebhodini kunye nobushushu bebhodi.

1.3. IYunithi yoNxibelelwano loMamkeli (HIU)

I-HIU yindawo yokufikelela kwi-Inter-Module Bus (IMB) yeModyuli. Ikwabonelela ngonikezelo lwamandla kunye namandla okusebenza acwangcisiweyo asekuhlaleni. I-HIU kuphela kwecandelo le-I/O Imodyuli yokuqhagamshela ngqo kwi-IMB Backplane. I-HIU iqhelekile kwiintlobo ezininzi zengqibelelo ephezulu ye-I/O kwaye inohlobo oluxhomekeke kunye noluhlu lwemveliso imisebenzi eqhelekileyo. I-HIU nganye iqulethe izilayi ezithathu ezizimeleyo, ezibizwa ngokuqhelekileyo njenge-A, B, kunye ne-C. Zonke i-interconnections phakathi kwezilayi ezithathu zibandakanya ukwahlukana ukuze kuthintelwe nayiphi na intsebenziswano ephosakeleyo phakathi kwezilayi. Isilayi ngasinye sithathwa njengeFault Containment Region (FCR), njengesiphoso kwisilayi esinye asinamphumo ekusebenzeni kwezinye izilayi. I-HIU ibonelela ngezi nkonzo zilandelayo zixhaphakileyo kwiiModyuli kusapho: • Unxibelelwano oluNyamezelwa yiFault ngesantya esiphezulu kunye neProsesa yeTMR ngojongano lwe-IMB. • FCR Interconnect Ibhasi phakathi kwezilayi ukuvota idatha ye-IMB engenayo nokusasaza idatha yeModyuli ye-I/O ephumayo kwi-IMB. • Ujongano lwedatha olulungiselelweyo olubekwe yedwa kwizilayi zeFIU. • Ulwabelwano lwamandla olungafunekiyo ombane odityanisiweyo we-24 Vdc chassis kunye nolawulo lwamandla ombane wengqiqo kwisekethe ye-HIU. • Amandla abekwe odwa ngokwemagnethi kwizilayi zeFIU. • Ujongano lwedatha yothotho kwiFPU yeemodyuli zemodyuli ze-LED. • Ikhonkco leSmartSlot phakathi kweeModyuli eziSebenzayo kunye nezokulinda ulungelelwaniso ngexesha lokutshintshwa kweModyuli. • Ukwenziwa kweMiqondiso yeDijithali ukwenza ukunciphisa idatha yendawo kunye nokuzixilonga. • Imithombo yenkumbulo yendawo yokugcina ukusebenza kweModyuli, uqwalaselo, kunye nedatha ye-I/O yendawo. • Ukugcinwa kwendlu ebhodini, ebeka iliso kwireferensi yombane, ukusetyenziswa kwangoku kunye nobushushu bebhodi.
