General Description Field I/O signals txuas mus rau FBM subsystem ntawm DIN rail mounted termination assemblies (TAs). Ntau hom TAs muaj nyob nrog FBMs los muab kev sib txuas ntawm I / O teeb liab, teeb liab txias, kev sib cais kho qhov muag los ntawm cov teeb liab surges, kev sib txuas hluav taws xob sab nraud, thiab / lossis kev sib txuas rau kev tiv thaiv FBM thiab / lossis cov khoom siv teb raws li qhov xav tau los ntawm FBM tshwj xeeb. Txij li cov yam ntxwv no tau tsim rau hauv cov kev sib dhos txiav tawm (qhov xav tau), hauv cov ntawv thov feem ntau tsis tas yuav muaj cov cuab yeej txiav tawm ntxiv rau kev ua haujlwm hauv cheeb tsam xws li kev tiv thaiv hluav taws xob lossis teeb liab (xws li fusing thiab hluav taws xob faib). Kev txiav tawm tuaj yeem siv tau nrog ib qho FBM207 lossis nrog ib khub rov qab (ob FBM207s). Lub DIN rail mounted termination assemblies txuas mus rau FBM subsystem baseplate los ntawm kev tshem tawm cov cables. Thaum siv nrog ib tug redundant module khub, qhov kev txiav txim los ua ke yog txuas nrog lub baseplate siv ib tug redundant adapter (P0926ZY). Lub DIN rail mounted TAs txuas mus rau lub redundant adapter los ntawm txoj kev tshem tawm cable. Cov kab hluav taws xob rau ob qho tib si thiab kev teeb tsa tsis tu ncua muaj nyob rau hauv ntau qhov ntev, txog li 30 meters (98 ko taw), tso cai rau kev txiav tawm cov rooj sib txoos rau hauv lub qhov rooj lossis hauv ib qho chaw nyob ib sab. Xa mus rau Table 2 ntawm nplooj ntawv 12 rau kev txiav cov kab zauv thiab cov lus qhia tshwj xeeb. Discrete Inputs Termination assemblies nrog discrete inputs txhawb kaum rau 2-xaim discrete input signals ntawm passive low voltage theem ntawm tsawg dua 60 V dc thiab active high voltage theem ntawm 125 V dc, 120 V ac, los yog 240 V ac. Active termination assemblies txhawb cov tswv yim teeb liab txias rau FBMs. Txhawm rau teeb tsa cov teeb meem, cov kev txiav tawm no tuaj yeem muab kev sib cais kho qhov muag, kev txwv tam sim no, txo suab nrov, txo qis hluav taws xob, lossis xaiv lub davhlau ya nyob twg los txuas rau sab nraud excitation voltage. 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 rau FBM207 yog hom ntsuas hluav taws xob. Voltage monitor inputs yuav tsum muaj qhov hluav taws xob sab nraud. Kev sib txuas lus nkag siab siv FBM pab +24 V dc lossis +48 V dc, muab rau txhua qhov kev tawm tswv yim ntawm lub rooj sib txoos, rau cov chaw ntub dej. Ib qho kev thauj khoom yuav tsis xav tau rau kev ua haujlwm zoo ntawm cov tswv yim channel. Ib lub diode tej zaum yuav xav tau rau dc inductive load nkaus xwb. High Voltage Discrete Inputs Lub high voltage input circuits txhawb 125 V dc, 120 V ac, los yog 240 V ac. Inputs tuaj yeem yog qhov ntsuas hluav taws xob lossis hloov hom. Voltage monitor inputs yuav tsum muaj qhov chaw voltage. Hloov cov inputs siv cov neeg siv khoom siv hluav taws xob excitation voltage siv rau cov terminals nplooj siab rau ntawm lub rooj sib txoos txiav thiab muab faib rau ntawm qhov kev txiav tawm mus rau txhua qhov kev tawm tswv yim. Txhawm rau kho cov teeb liab, voltage attenuation circuits yog nyob rau ntawm tus ntxhais boards mounted nyob rau hauv lub tivthaiv npog ntawm lub rooj sib txoos txiav.
