PHD-12TZ-*11
Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko: i-PHD-12TZ-*11, ukufakwa kwesiginali ye-RTD, ukufakwa okukodwa nokuphuma okubili.
Isithiyo sokuphepha esihlukanisiweko singatjhugulula isiginali yokufaka ye-RTD endaweni eyingozi ibe yi-4-20mA yesiginali bese idlulisela endaweni ephephileko. Isekhethi ifakwe isiginali ye-RTD eyodwa yokufaka kanye nokukhipha okubili kwe-DC.
Isiginali yokuphuma engu-4-20mA, ingahlelwa ngokuhlakanipha. Ibanga langempela le-RTD lingasethwa yikhomphyutha.
I-PHD-12TZ-*11, "*" itjengisa umhlobo wokufaka we-RTD, sibawa usebenzise ikhodi ukutjengisa.
Umkhiqizo lo udinga umthombo wamandla wangaphandle we-20~35VDC.

Qaphela: 1. PHD-11TZ - * 1 ayifaki ingcenye yokukhipha 2
2. Umsebenzi we-power rail ngumsebenzi ongakhetha kiwo, begodu abasebenzisi kufuze bacacise indlela yokuphakelwa kwamandla lokha nawufaka i-oda
Ukukhethwa kwezixhumanisi zesitimela samandla kungabhekisa ekhasini 89 le "Isithasiselo"
3. Lokha nawufaka i-RTD yeentambo ezintathu, kuyatlhogeka bona uqinisekise bona iintambo ezintathu iintambo zinobude obulinganako ngendlela ekungakghoneka ngayo
4. Lokha nawufaka i-RTD eneentambo ezimbili, amatheminali wokuvikela 4 no-2 kufanele abe isekhethi emfitjhani
