Cov tswv yim
Kev nyab xeeb nkag mus rau Kev Nyab Xeeb Kev Nyab Xeeb yuav yog De-energize rau kev tawm tswv yim lossis analog inputs.

Digital inputs
De-energize rau kev tawm tswv yim tawm tswv yim (feem ntau hu ua tsis muaj kev nyab xeeb) yuav siv rau txhua qhov kev nyab xeeb digital inputs. Tus naj npawb ntawm kev soj ntsuam kev nyab xeeb uas yuav tsum tau muaj rau txhua qhov kev nyab xeeb yuav nyob ntawm qhov tseem ceeb ntawm qib kev nyab xeeb (kev nyab xeeb kev nyab xeeb) yuav tsum ua tiav, 100% pov thawj kev ntsuas yuav tsum tau ua thiab qib kev kuaj mob muaj los ntawm cov cuab yeej teb.
Txhua qhov kev ruaj ntseg digital inputs yuav raug xa mus rau Digital Input Termination Card. Qhov twg qhov kev ruaj ntseg ruaj ntseg yuav tsum muaj ntau tshaj ib lub teb sensor saib xyuas qhov kev nyab xeeb, txhua qhov ntawm cov sensors no yuav tsum yog, qhov ua tau zoo, xaim rau cais Daim Ntawv Teev Npe. Qhov Simplex ib feem ntawm daim npav txiav tawm (piv txwv li, fuses) yuav tsum raug txiav txim siab rau kev txheeb xyuas kev ntseeg tau ua ib feem ntawm lub voj voog.

Daim npav Termination yuav txuas nrog Triguard SC300E Input Module ntawm tus qauv system cable uas txuas mus rau lub qhov (socket) ntawm qhov tsim nyog Daim Ntawv Kho Kho Kub Kho Mob lossis chassis qhov.
Los ntawm daim npav kho kub kho adapter, qhov xav tau, thiab lub chassis backplane connector lub teeb liab tawm tswv yim txuas nrog rau qhov teeb tsa digital input qhov chaw nyob qhov twg Digital Input Module yuav nyob.
Tag nrho cov chassis slots thiab, qhov twg yuav tsum tau, nws cov kev kho kub tus khub slots configured rau lub Digital Input Module yuav tsum muaj cov polarization yuam sij haum thiab configured rau hom module raws li tau teev nyob rau hauv Module thiab Chassis User Manuals.
Qhov twg qib kev ruaj ntseg yuav tsum tau siv cov sensors cais los saib xyuas tib yam kev nyab xeeb lawv yuav tsum tau teeb tsa kom cais cov Digital Input Modules qhov ua tau zoo.

Analog inputs
Analog transmitters yog siv los saib xyuas qhov tsis muaj kev nyab xeeb thiab muab qhov nce qib ntawm kev kuaj mob nrog rau kev nkag siab yooj yim tsis muaj kev nyab xeeb digital. Analog signals yeej ib txwm muab qhov tseem ceeb nyob rau hauv ib qho kev khiav hauj lwm ntau yam. Rau kev nyab xeeb ntsig txog kev xa khoom, qhov no yuav tsum yog 4-20 mA lossis 1-5 volts uas tso cai rau kev ua txhaum hauv qab no hais tias 3 mA (0.75 V) thiab 20 mA (5 V). Yog tias yuav tsum tau kuaj pom ntau dhau, yuav tsum siv 0-10 V input module. Txhua qhov kev soj ntsuam tsis raug los ntawm cov teeb liab analog yuav tsum tau siv los ntawm daim ntawv thov software los tsim cov txiaj ntsig tsis muaj kev nyab xeeb (piv txwv li, lub tshuab xa hluav taws xob ua tsis tiav xav tau kaw).
Tus naj npawb ntawm cov analog transmitters siv los saib xyuas qhov ntsuas kev nyab xeeb yuav yog nyob ntawm qib kev ncaj ncees (kev nyab xeeb kev faib tawm) qhov xav tau ntawm lub voj, 100% pov thawj kev ntsuas lub voj voog ntawm lub voj thiab qib kev kuaj mob muaj los ntawm lub tshuab xa tawm.
Lub teb analog teeb liab yog xaim mus rau Analog Input Termination Card. Qhov twg cov qib kev ruaj ntseg yuav tsum tau siv ntau tshaj ib lub transmitter los soj ntsuam qhov kev nyab xeeb tsis, ces cov analog input signals ntxiv yuav tsum tau wired rau cais Termination Cards qhov twg siv tau. Lub Simplex circuitry ntawm daim npav txiav yuav tsum raug txiav txim siab rau kev ntseeg tau raws li ib feem ntawm lub voj voog xa xov (piv txwv li, fuses thiab saib xyuas cov resistors qhov twg haum). Saib daim duab B-1.
Lub teeb liab txuas nrog los ntawm daim npav txiav mus rau Triguard SC300E input module ntawm tus qauv system cable, uas txuas mus rau lub qhov (socket) ntawm qhov tsim nyog Kub Kho Adapter Card lossis chassis connector.
