PHD-11TD-21

Ukuhlolisisa

Isithiyo sokuphepha esihlukanisiweko ehlangothini lokuthola: i-PHD-11TD-21, ukungena nokukhipha kwe-analog, ukufakwa okukodwa nokukhipha okukodwa.

^ 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 wangaphandle we-20-35VDC.

^ Umkhiqizo lo usekela isiginali ye-HART kanye ne-alamu yokuvala.

* Qaphela: Nangabe udinga amanye amapharamitha womkhiqizo lo, sibawa uthintane nokusekela kwethu kwezobuchwepheshe. Nangabe umphumela ungamanye amapharamitha, utjengiswa yinomboro 9, begodu amapharamitha athileko atjengiswa ngemva kwenomboro yemodeli.

Ukuhlolisisa

I-analog yokufaka isithiyo sokuphepha esihlukanisiweko sinikela ngamandla ahlukanisiwekoukuphakela iinsetjenziswa ezimbili - nezintathu zokudlulisa iintambo eendaweni eziyingozi.

Isiginali ye-4~20mA eyakhiwe mtjhini wokudlulisa namkha umthombo wamanje idluliselwa ukusuka endaweni eyingozi ukuya endaweni ephephileko, ngaleyo ndlela iqhuba umthwalo endaweni ephephileko. Kuma-transmitter amabili nofana amathathu weentambo nofana amatshwayo womthombo wamanje, isithiyo sokuphepha lesi sisekela ukukhulumisana okuqondileko kwesiginali yedijithali ye-Hart ebekwe phezu kwesiginali ye-4~20mA begodu inomsebenzi we-alamu yokuphuka kwentambo.

Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.
