Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe sokufakwa kwe-analog sinikeza ukunikezwa kwamandla okuhlukanisiwe kwama-transmitter amabili namathathu ezindaweni eziyingozi. Isignali engu-4~20mA ekhiqizwa yi-transmitter noma umthombo wamanje idluliselwa kusuka endaweni eyingozi iye endaweni ephephile, ngaleyo ndlela iqhube umthwalo endaweni ephephile. Kwabathumeli bezintambo ababili noma abathathu noma amasignali omthombo wamanje, lesi sisithiyo sokuphepha sisekela ukuxhumana okuqondile kwesignali yedijithali ye-Hart ebekwe phezu kwesignali engu-4~20mA futhi sinomsebenzi we-alamu yokuphuka kwentambo. Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zokunikezwa kwamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.
