Ukuhlolisisa
I-analog output isolated safety barrier ene-surge protection barrier ingenza ukudluliswa kwe-4~20mA amatshwayo ukusuka eensetjenzisweni ezisendaweni ephephileko ukuya endaweni eyingozi, iqhube i-valve positioner, i-elekthri/pneumatic converter neminye imitjhini endaweni, begodu isekele ukudluliswa okubili kwama-HART amasignali wedijithali ngomsebenzi we-alamu ye-wirebreak. Umkhiqizo lo udinga umthombo wamandla ozijameleko, begodu umthombo wamandla, okufakwako nokuphumako kuhlukaniswe.

Ubukhulu
Imidwebo ye-Skema
Qaphela: Umsebenzi we-power rail ngumsebenzi ongakhetha kiwo, begodu abasebenzisi kufuze bacaciseindlela yokuphakelwa kwamandla lokha nawufaka i-oda
Ukukhethwa kwezixhumanisi zesitimela samandla kungabhekisa ekhasini 89 le "Isithasiselo"
