I-PHD-12TD-211

Okokufaka endaweni enobungozi

Isignali yokufaka

Isidluliseli esinezintambo ezimbili noma ezintathu noma umthombo wamanje (isignali yedijithali ye-HART)

I-voltage yokusatshalaliswa kwe-transmitter

I-voltage yesekethe evulekile ingu-≤28V, kanti i-voltage yokuphuma ingu-≥15.5V uma isekethe ingu-20mA.

Umphumela endaweni ephephile

Isignali yokuphuma

4~20 mA(isignali yedijithali ye-HART)

Umthwalo wokukhipha

Uma ukhipha i-20mA, 0~500 Ω (kungenziwa ngezifiso)
Uhlobo lokukhipha i-voltage olukhethwayo, ukumelana nomthwalo RL ≥ 330k Ω

Amapharamitha ayisisekelo

I-voltage yokunikezela

20~35VDC

Ukusetshenziswa kwamandla

Uma ugesi ongu-24V, okukhipha okungu-20mA
≤95mA(PHD-12TD-211+)

Isikhombisi se-LED

Okuluhlaza: inkomba yamandla

Isikhathi sokuphendula

2ms ukufinyelela ku-90% wenani lokugcina

Ukukhukhuleka kwezinga lokushisa

0.005% FS/℃

Amapharamitha okushisa

Izinga lokushisa lokusebenza: -20℃ ~ +60℃,
Izinga lokushisa lokugcina: -40℃ ~ +80℃

Umswakama ohlobene

10%~95% RH akukho ukujiya

Amandla okuvala uthuli

Phakathi kohlangothi oluphephile ngokwemvelo kanye nohlangothi oluphephile ngokwemvelo (≥3000VAC/min); phakathi kokunikezwa kwamandla kanye nohlangothi oluphephile ngokwemvelo (≥1500VAC/min)

Ukumelana nokushisa

≥100MΩ (phakathi kokufaka/ukukhipha/ukunikezwa kwamandla)

Ukuhambisana kwe-electromagnetic

Ngokusho kwe-IEC 61326-1 (GB/T 18268), i-IEC 61326-3-1

I-MTBF

Amahora angu-100000

Izidingo zentambo

Isigaba esiphambeneyo ≥ 0.5mm2; Amandla okuvikela ≥ 500V

Imishini yasensimini esebenzayo

Isiginali yokudlulisela noma yomthombo wamanje (i-HART) enama-wire amathathu, amabili, anezintambo ezintathu

Indawo yokufaka

Indawo yokufaka: Uma ifakwe endaweni ephephile, ingaxhunywa kumathuluzi okuphepha angaphakathi ezindaweni eziyingozi kuze kufike ku-Zone 0, IIC, Zone 20, kanye ne-IIIC.

Isitifiketi esiphephile ngokwendalo
