Olona phawu luqhelekileyo lusetyenziswayo lwe-analog yombane kushishino kukuhambisa ubungakanani be-analog nge-4 ~ 20mA DC yangoku.Isizathu sokusebenzisa umqondiso wangoku kukuba akulula ukuphazamiseka, kwaye ukuchasana kwangaphakathi komthombo wangoku akupheli.Uluhlu lokumelana nocingo kwi-loop aluchaphazeli ukuchaneka, kwaye lunokudluliselwa ngamakhulu eemitha kwisibini esijijekileyo esiqhelekileyo.Umda ophezulu we-20mA ngenxa yeemfuno zobungqina bokuqhuma: amandla e-spark abangelwa ukuphulwa kwangoku kwe-20mA ayanele ukutshisa igesi.Isizathu sokuba kutheni umda ongaphantsi ungamiselwanga njenge-0mA kukufumanisa umgca ophukileyo: awuyi kuba ngaphantsi kwe-4mA ekusebenzeni okuqhelekileyo.Xa umgca wothumelo uphukile ngenxa yesiphoso kwaye i-loop yangoku yehla ukuya kwi-0, i-2mA ihlala ibekwe njengexabiso le-alamu yomgca ophukileyo.
