Qhov feem ntau siv cov qauv analog kom muaj nuj nqis hluav taws xob hauv kev lag luam yog xa cov analog kom muaj nuj nqis nrog 4 ~ 20mA DC tam sim no.Yog vim li cas rau kev siv lub teeb liab tam sim no yog tias nws tsis yooj yim rau kev cuam tshuam nrog, thiab qhov kev tawm tsam sab hauv ntawm qhov tam sim no yog infinite.Cov hlau tsis kam series nyob rau hauv lub voj tsis cuam tshuam qhov raug, thiab tuaj yeem xa mus rau ntau pua meters ntawm tus khub twisted zoo tib yam.Qhov siab tshaj ntawm 20mA yog vim yog qhov yuav tsum tau tawg: lub txim hluav taws xob tshwm sim los ntawm kev tawg tam sim no ntawm 20mA tsis txaus rau ignite cov roj.Yog vim li cas vim li cas qhov qis qis tsis tau teem caij raws li 0mA yog txhawm rau txheeb xyuas cov kab tawg: nws yuav tsis qis dua 4mA hauv kev ua haujlwm ib txwm muaj.Thaum cov kab sib kis tau tawg vim qhov ua txhaum thiab lub voj tam sim no poob rau 0, 2mA feem ntau yog teem raws li qhov tawg kab tswb nqi.
