Ukuhlolisisa
I-analog yokufaka isithiyo sokuphepha esinomsebenzi wokuvikela ukukhuphuka kwegazi sinikela ngokuphakelwa kwamandla okuhlukileko kwama-transmitter amabili namathathu 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. Kwama-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.

Qaphela: 1. I-PHD-11TD-21+ ayifaki ingcenye ye-2 yokuphuma.
2. Ukuphakelwa kwamandla wesitimela samandla kungumsebenzi ongakhetha kiwo. Abasebenzisi kufuze
tjho indlela yokuphakelwa kwamandla lokha nawu-oda.
Sibawa uqale ukunamathiselwa ekhasini 89.
