Product Overview

Lub Trusted® TMR 24 Vdc Digital Output Module cuam tshuam rau 40 cov khoom siv teb. Triplicated diagnostic tests yog ua nyob rau hauv lub Module nrog rau kev ntsuas rau tam sim no, thiab voltage ntawm txhua feem ntawm cov tso zis tso zis channel. Kev ntsuam xyuas kuj tau ua rau daig rau thiab daig tawm tsis ua tiav. Kev ua txhaum cai yog ua tiav los ntawm Triple Modular Redundant (TMR) architecture nyob rau hauv Module rau txhua qhov ntawm 40 cov zis tawm. Tsis siv neeg kab saib xyuas cov cuab yeej teb yog muab. Cov yam ntxwv no ua rau lub Module txhawm rau txheeb xyuas ob qho tib si qhib thiab luv luv Circuit Court tsis ua haujlwm hauv thaj chaw thaiv thiab cov khoom siv thauj khoom. Lub Module muab on-board Sequence of Events (SOE) qhia nrog rau kev daws teeb meem ntawm 1 ms. Kev hloov pauv ntawm lub xeev ua rau muaj kev nkag mus rau SOE. Cov zis hluav taws xob tau txiav txim siab los ntawm qhov ntsuas hluav taws xob thiab ntsuas tam sim no ntawm-board Module. Qhov Module no tsis raug pom zoo rau kev sib txuas ncaj qha rau thaj chaw muaj kev phom sij thiab yuav tsum tau siv ua ke nrog Intrinsic Safety Barrier li

Lub TMR 24 Vdc Digital Output Module yog ib tug tswv cuab ntawm Kev Ntseeg ntau yam ntawm Input/Output (I/O) Modules. Txhua qhov Trusted I/O Modules sib koom ua haujlwm thiab daim ntawv. Nyob rau theem dav tshaj plaws, tag nrho I / O Modules interface rau Inter-Module Bus (IMB) uas muab lub zog thiab tso cai rau kev sib txuas lus nrog TMR Processor. Tsis tas li ntawd, tag nrho cov Modules muaj lub teb interface uas siv los txuas rau Module cov cim tshwj xeeb hauv thaj teb. Txhua Modules yog Triple Modular Redundant (TMR).

1.1.Field Termination Unit (FTU)

Field Termination Unit (FTU) yog ntu ntawm I / O Module uas txuas tag nrho peb FIUs mus rau ib qho kev sib tshuam. FTU muab Pab Pawg Fail Safe Switches thiab passive Cheebtsam tsim nyog rau cov teeb liab txias, tiv thaiv dhau-voltage, thiab EMI / RFI lim. Thaum muab tso rau hauv Trusted Controller lossis Expander Chassis, FTU field connector interconnects mus rau Field I / O Cable Assembly txuas rau tom qab ntawm Chassis. Qhov txuas SmartSlot tau dhau los ntawm HIU mus rau kev sib txuas ntawm FTU. Cov teeb liab no ncaj qha mus rau qhov chaw txuas thiab tswj kev sib cais los ntawm I / O cov cim ntawm FTU. Qhov txuas SmartSlot yog qhov kev sib txuas ntse ntawm Active thiab Standby Modules rau kev sib koom tes thaum hloov Module.

1.2.Field Interface Unit (FIU)

Field Interface Unit (FIU) yog ntu ntawm Module uas muaj cov kab hluav taws xob tshwj xeeb tsim nyog los cuam tshuam rau cov hom phiaj I / O cov cim. Txhua Module muaj peb FIUs, ib qho rau ib daim. Rau TMR 24 Vdc Digital Output Module, FIU muaj ib theem ntawm cov zis hloov qauv, thiab sigma-delta (ΣΔ) tso zis hluav taws xob rau txhua qhov ntawm 40 qhov chaw tawm. Ob qhov ntxiv ΣΔ circuits muab kev xaiv saib xyuas ntawm sab nraud I / O cov khoom siv hluav taws xob.

FIU tau txais lub zog cais tawm los ntawm HIU rau kev xav. FIU muab lub zog txias ntxiv rau kev ua haujlwm voltages xav tau los ntawm FIU circuitry. Ib qho kev sib cais 6.25 Mbit / sec serial txuas txuas txhua FIU rau ib qho ntawm HIU hlais. FIU kuj ntsuas ntau yam ntawm on-board "kev tu tsev" cov cim qhia uas pab saib xyuas kev ua haujlwm thiab kev ua haujlwm ntawm Module. Cov teeb liab no suav nrog cov khoom siv hluav taws xob hluav taws xob, kev siv tam sim no, kev siv hluav taws xob ntawm lub rooj tsav xwm thiab lub rooj tsav xwm kub.

1.3. Host Interface Unit (HIU)

Lub HIU yog lub ntsiab lus nkag mus rau Inter-Module Bus (IMB) rau Module. Nws kuj muab kev faib hluav taws xob thiab hauv zos programmable ua lub zog. HIU yog tib seem ntawm I/O Module los txuas ncaj qha mus rau IMB Backplane. HIU yog ib qho ntawm feem ntau siab ncaj siab I / O hom thiab muaj hom kev vam khom thiab cov khoom siv ntau yam haujlwm. Txhua HIU muaj peb daim ntawv ywj pheej, feem ntau hu ua A, B, thiab C. Txhua qhov kev sib txuas ntawm peb lub hlais sib xyaw ua ke los pab tiv thaiv kev sib cuam tshuam ntawm cov hlais. Txhua daim hlais raug suav tias yog Fault Containment Region (FCR), vim tias qhov txhaum ntawm ib daim hlais tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lwm cov hlais. HIU muab cov kev pabcuam hauv qab no uas muaj rau cov Modules hauv tsev neeg: • Kev sib txuas lus siab ceev nrog TMR Processor ntawm IMB interface. • FCR Interconnect Bus ntawm cov hlais los pov npav cov ntaub ntawv IMB tuaj thiab faib tawm cov ntaub ntawv I/O Module rau IMB. • Galvanically cais cov ntaub ntawv serial interface rau FIU hlais. • Redundant fais fab sib koom ntawm dual 24 Vdc chassis muab qhov hluav taws xob thiab kev tswj fais fab rau lub zog logic rau HIU circuitry. • Magnetically cais hwj chim rau FIU hlais. • Serial data interface rau FPU rau Module raws li txoj cai LEDs. • SmartSlot txuas ntawm Active thiab Standby Modules rau kev sib koom ua ke thaum hloov Module. • Digital Signal Processing los txo cov ntaub ntawv hauv zos thiab kuaj tus kheej. • Cov peev txheej nco hauv zos rau khaws cia Module ua haujlwm, teeb tsa, thiab cov ntaub ntawv I/O teb. • On-board tsev tu, uas saib xyuas cov kev siv voltages, tam sim no noj thiab board kub.
