Isishwankathelo
Isithintelo sokhuseleko esifakwe kwi-analog sibonelela ngombane ozimeleyo kwiitransmitter ezimbini nezintathu kwiindawo ezinobungozi. Isignali ye-4~20mA eveliswa yitransmitter okanye umthombo wangoku idluliselwa ukusuka kwindawo enobungozi ukuya kwindawo ekhuselekileyo, ngaloo ndlela iqhuba umthwalo kwindawo ekhuselekileyo. Kwiitransmitter ezimbini okanye ezintathu zentambo okanye imiqondiso yomthombo wangoku, esi sithintelo sokhuseleko sixhasa unxibelelwano oluya kwicala elinye lwesignali yedijithali yeHart ebekwe kwisignali ye-4~20mA kwaye inomsebenzi we-alamu yokuqhekeka kwentambo. Le mveliso ifuna umbane ozimeleyo, kunye nombane ohlukeneyo, i-input, kunye ne-output terminals.
