Nonincendive FTAs (tam sim no limiting) Qee qhov Field Termination Assemblies (FTAs) uas tau siv nyob rau hauv Cov Txheej Txheem Ua Haujlwm Zoo Tshaj Plaws muaj cov resistors hauv cov khoom siv hluav taws xob los txwv qhov tam sim no muaj nyob rau hauv lub teb terminals. Cov khoom siv hluav taws xob no tau raug tshuaj xyuas thiab tau lees paub los ntawm Factory Mutual tias yog Nonincendive. Qhov no txhais tau hais tias yog tias cov kab hluav taws xob hauv teb tau raug qhib, luv luv, lossis hauv av thiab HPM ua haujlwm ib txwm, cov xaim yuav tsis tso tawm lub zog txaus los ua kom muaj hluav taws kub hauv qhov chaw taws teeb. Table 5-3 yog ib daim ntawv teev cov analog input, analog output, thiab digital input FTAs uas muaj Nonincendive outputs. Tsis tas li ntawd, thaum digital output circuits ntawm digital output FTA yog tam sim no thiab voltage txwv rau cov qib tsim nyog los ntawm tus neeg siv, cov zis digital FTA kuj tuaj yeem suav tias yog Nonincendive. Cable thiab load tsis (qhov chaw tsis muaj) Yuav kom paub meej tias lub teb circuits tsis muaj peev xwm ntawm igniting ib tug teev flammable vapor, qhov luaj li cas ntawm cov cable thiab load tsis yuav tsum tau paub thiab tswj. Table 5-3 muab qhov siab tshaj plaws tso cai qhov tseem ceeb ntawm cov kev txwv rau txhua qhov FTAs uas tau teev tseg hauv cov lus. Kev pom zoo ntawm hluav taws xob code Feem ntau, kev xaim hluav taws xob hauv Division 2 qhov chaw muaj kev phom sij yuav tsum tau ua raws li cov cai hauv zos; Txawm li cas los xij, hauv qee qhov kev txiav txim siab, Cov xov hlau tsis muaj zog yuav tsum tsis ua raws li cov cai ntawm Division 2 thaiv kab, tab sis tuaj yeem siv txoj kev xaim uas tsim nyog rau qhov chaw zoo tib yam. Saib ANSI/ISA S12.12, ntu "Cov Khoom Siv Hluav Taws Xob Rau Kev Siv Hauv Chav Kawm I, Division 2 Hazardous [Classified] Qhov Chaw." Tam sim no limiting resistor tus nqi Tus nqi ntawm cov resistors ntawm cov npe FTAs raug xaiv kom paub tseeb tias qhov phem tshaj plaws luv luv Circuit Court tam sim no nyob rau hauv ib qho chaw txaus ntshai ntawm tsawg dua 150 milliamps rau cov khoom siv ua haujlwm. Raws li NFPA ntawv tshaj tawm #493, Intrinsically Safe Apparatus rau Siv nyob rau hauv Division 1 Hazardous Locations, 150 milliamps los ntawm ib tug 24 Vdc qhov chaw yog qis dua qhov pib ignition nyob rau hauv ib tug resistive Circuit Court rau gases nyob rau hauv pab pawg A txog D ib puag ncig.
