I-PHD-12TZ-*11
Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe: I-PHD-12TZ-*11, okokufaka kwesignali ye-RTD, okokufaka okukodwa kanye nokokukhipha okubili.
Isithiyo sokuphepha esihlukanisiwe singaguqula isignali yokufaka ye-RTD endaweni eyingozi ibe yi-4-20mA ekhishwayo yesignali bese siyidlulisela endaweni ephephile. Isekethe ifakwe i-single RTD signal input kanye ne-DC dual output.
Isignali yokukhipha engu-4-20mA, ingalungiswa ngokuhlakanipha. Ububanzi bangempela be-RTD bungasethwa yikhompyutha.
I-PHD-12TZ-*11, "*" ikhombisa uhlobo lokufaka lwe-RTD, sicela usebenzise ikhodi ukuze ubonise.
Lo mkhiqizo udinga ugesi wangaphandle ongu-20 ~ 35VDC.
Izinhlobo zesignali yokufaka kanye nobubanzi bokulinganisa
| Ikhodi | Imodeli ye-RTD | Ububanzi bokulinganisa | Ibanga elincane | Ukunemba kokuguqulwa |

Qaphela: 1. I-PHD-11TZ - * 1 ayifaki ingxenye yokukhipha 2
2. Umsebenzi wesitimela samandla ngumsebenzi ongawukhetha, futhi abasebenzisi kudingeka bacacise indlela yokunikezwa kwamandla lapho ubeka i-oda
Ukukhethwa kwezixhumi zesitimela sikagesi kungabhekisela ekhasini 89 le-"Annex"
3. Uma ufaka i-RTD yezintambo ezintathu, kubalulekile ukuqinisekisa ukuthi ezintathu izintambo zilingana ngobude ngangokunokwenzeka
4. Uma ufaka i-RTD enezintambo ezimbili, amatheminali okuvikela ukuphepha 4 no-2 kumele abe i-short circuits
