Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko ehlangothini lokuthola: i-PHD-22HD-2121, ukufakwa nokukhipha kwe-analog, ukufakwa okubili nokukhipha okubili.
Isithiyo esihlukanisiweko singahlukanisa begodu sidlulisele isignali ye-4~20mA nofana isignali ye-DC 4~20 mA eyenziwe mtjhini wokudlulisa endaweni eyingozi ukuya endaweni ephephileko. Lokha umtjhini wokudlulisa uneentambo ezimbili nofana ezintathu, isithiyo sokuphepha sinikela umtjhini wamandla.
Umkhiqizo lo udinga umthombo wamandla ozijameleko.
Umkhiqizo lo usekela isiginali ye-HART kanye ne-alamu yokuvala.
