Isishwankathelo
Igalelo le-analog elikhethekileyo lomqobo wokhuseleko kunye nomsebenzi wokukhusela utyando lubonelela ngobonelelo lwamandla oluzimeleyo kwii-transmitters ezimbini kunye nezintathu zocingo kwiindawo ezinobungozi. Umqondiso we-4-20mA owenziwe ngumthumeli okanye umthombo wangoku uthunyelwa ukusuka kwindawo enobungozi ukuya kwindawo ekhuselekileyo, ngaloo ndlela uqhuba umthwalo kwindawo ekhuselekileyo. Kwii-transmitters ezimbini okanye ezintathu zocingo okanye izibonakaliso zomthombo wangoku, lo mqobo wokhuseleko uxhasa unxibelelwano lwe-bidirectional ye-Hart yedijithali yesiginali efakwe kwi-4-20mA uphawu kwaye inomsebenzi we-alam yokuqhawula ucingo.
Le mveliso ifuna unikezelo lwamandla oluzimeleyo, kunye nonikezelo lwamandla olulodwa, igalelo, kunye neetheminali eziphumayo.
