Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe sokufaka i-analog esinomsebenzi wokuvikela ukukhuphuka 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 izimpawu zomthombo 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 zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.

Qaphela: 1. I-PHD-11TD-21+ ayifaki ingxenye engu-2 yokukhipha.
2. Ukunikezwa kwamandla kwesitimela sikagesi kungumsebenzi ongawukhetha. Abasebenzisi kudingeka
cacisa imodi yokunikezwa kwamandla uma u-oda.
Sicela ubheke okunamathiselwe ekhasini 89.
