Kev tsiv teb tsaws Kev Siv Lub Rooj Sib Tham Sib Tham Thaum FBM217 yog siv los hloov 100 Series FBMs, nws cov kev sib txuas txiav txiav txiav txim siab raws li qhov twg 100 Series FBM raug hloov. Feem ntau, 100 Series FBM tau hloov pauv yog FBM tseem ceeb thiab tej zaum yuav tau siv nrog kev nthuav dav FBM. Ib qho FBM217 muab kev sib txuas lus I/O rau ob qho tib si 100 Series sib npaug lub ntsiab thiab nthuav dav TAs. Txhawm rau muab cov terminals txaus rau cov ntaub ntawv tawm tswv yim, ob lub rooj sib tham txiav tawm yog siv nrog FBM217 - ib qho rau cov khoom siv hluav taws xob txuas rau lub ntsiab FBM hloov, thiab ib qho rau cov khoom siv hluav taws xob rau kev hloov pauv FBM. Lub "expansion" termination assembly yog daisychained mus rau "lub ntsiab" kev txiav txim los ntawm cov expansion cables teev nyob rau hauv Table 3 nyob rau nplooj 16. Lub rooj "FUNCTIONAL SPECIFICATIONS - TERMINATION ASSEMBLIES" nyob rau nplooj 9 teev cov kev txiav txim sib dhos uas yuav tsum tau los hloov ob lub 100 series loj FBMs. Xwb, FBM217 tuaj yeem lees txais kev xa xov los ntawm Termination Assembly Adapter (TAA) es tsis txhob siv cov rooj sib tham txiav tawm thaum hloov 100 Series FBMs. Qhov no tau tham hauv Termination Assembly Adapter Modules rau 100 Series Hloov Kho (PSS 21H-2W4 B4). Discrete Inputs Ntau yam kev txiav tawm cov rooj sib tham muaj los txhawb kev cuam tshuam ntawm cov teeb liab hauv cheeb tsam mus rau qib qis FBM input circuits. Lub rooj sib txoos ua haujlwm txiav tawm txhawb cov tswv yim teeb liab txias rau FBM nrog rau kev sib cais channel. Nco ntsoov tias rau kev teeb tsa uas siv lub ntsiab thiab nthuav dav TAs, I / O teeb liab txias circuits yog tsim los ua raws li 100 Series FBM I / O subsystem. Qhov no muab rau kev ua haujlwm I / O sib npaug thaum hloov kho los ntawm 100 Series rau 200 Series kho vajtse. Lub teeb liab cua txias circuits yog nyob rau ntawm tus ntxhais boards uas tau mounted nyob rau hauv lub tivthaiv npog ntawm lub termination assemblies. Txhawm rau kho cov teeb meem, cov kev txiav tawm no muab kev sib cais kho qhov muag, kev txwv tam sim no, qhov hluav taws xob attenuation thiab xaiv lub davhlau ya nyob twg los txuas rau cov khoom siv hluav taws xob sab nraud. Tsawg Voltage Discrete Inputs Cov khoom siv hluav taws xob tsawg (tsawg dua 60 V dc) siv cov kev sib dhos tsis sib haum. Inputs yog qhov ntsuas hluav taws xob lossis hom kev sib cuag. Voltage monitor inputs yuav tsum muaj qhov hluav taws xob sab nraud. Kev sib txuas lus nkag siab siv FBM pab +24 V dc fais fab mov rau cov chaw ntub dej. Ib qho kev thauj khoom yuav xav tau rau kev ua haujlwm kom raug ntawm cov khoom nkag. High Voltage Discrete Inputs Lub high voltage input circuits txhawb 125 V dc, 120 V ac, los yog 240 V ac. Voltage monitor inputs yuav tsum muaj qhov chaw voltage. Qee cov qauv ntawm lub rooj sib txoos txiav tawm muaj ib khub ntawm sab nraud excitation voltage terminals, uas faib cov neeg siv khoom siv wetting voltage rau txhua qhov kev tawm tswv yim ntawm lub rooj sib txoos. Cov terminals no tso cai rau lub zog teb los ua daisy chained ntawm lub davhlau ya nyob twg los ua ke.
