I-PHD-11TD-21

Ukubuka konke

Isithiyo sokuphepha esihlukanisiwe ohlangothini lokutholwa: i-PHD-11TD-21, okokufaka nokukhipha kwe-analog, okokufaka okukodwa nokukhipha okukodwa.

^ Isithiyo esihlukanisiwe singahlukanisa futhi sidlulisele isignali engu-4~20mA noma isignali ye-DC 4~20 mA ekhiqizwe yi-transmitter endaweni eyingozi endaweni ephephile. Uma i-transmitter iyisistimu yezintambo ezimbili noma ezintathu, isithiyo sokuphepha sinikeza amandla ku-transmitter.

^ Lo mkhiqizo udinga ugesi wangaphandle ongu-20-35VDC.

^ Lo mkhiqizo usekela isignali ye-HART kanye ne-alamu yokunqamula.

* Qaphela: Uma udinga amanye amapharamitha alo mkhiqizo, sicela uxhumane nosekelo lwethu lobuchwepheshe. Uma umphumela ungeminye imingcele, ukhonjiswa yinombolo 9, kanti amapharamitha athile akhonjiswa ngemuva kwenombolo yemodeli.

Isithiyo sokuphepha esihlukanisiwe sokufakwa kwe-analog sinikeza amandla ahlukanisiweukuhlinzekwa kwama-transmitter amabili namathathu ezindaweni eziyingozi.

Isignali engu-4~20mA ekhiqizwa yi-transmitter noma umthombo wamanje idluliselwa isuka endaweni eyingozi iye endaweni ephephile, ngaleyo ndlela iqhube umthwalo endaweni ephephile. Kuma-transmitter amabili noma amathathu noma amasignali omthombo wamanje, lesi sivimbelo sokuphepha sisekela ukuxhumana okuqondiswayo 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.
