I-PHD-11TD-21

Isishwankathelo

Isithintelo sokhuseleko esizimeleyo kwicala lokufumanisa: i-PHD-11TD-21, igalelo kunye nemveliso ye-analog, igalelo elinye kunye nemveliso enye.

^ Umqobo ohlukanisiweyo ungawuhlukanisa kwaye udlulisele isignali ye-4 ~ 20mA okanye isignali ye-DC 4 ~ 20 mA eyenziwe ngumthumeli kwindawo eyingozi kwindawo ekhuselekileyo. Xa umthumeli enezixhobo ezimbini okanye ezintathu, umqobo wokhuseleko unika amandla kumthumeli.

^ Le mveliso ifuna umbane wangaphandle we-20-35VDC.

^ Le mveliso ixhasa isignali ye-HART kunye ne-alamu yokuqhawula.

* Qaphela: Ukuba ufuna ezinye iiparameters zale mveliso, nceda unxibelelane nenkxaso yethu yobugcisa. Ukuba imveliso yezinye iiparameters, iboniswa yinombolo 9, kwaye iiparameters ezithile ziboniswa emva kwenombolo yomzekelo.

Isishwankathelo

Umqobo wokhuseleko ozimeleyo ongenayo i-analog unika amandla ahlukeneyoukubonelela ngee-transmitter ezimbini nezithathu kwiindawo ezinobungozi.

Isignali ye-4~20mA eveliswa yitransmitter okanye umthombo wangoku idluliselwa ukusuka kwindawo enobungozi ukuya kwindawo ekhuselekileyo, ngaloo ndlela iqhuba umthwalo kwindawo ekhuselekileyo. Kwiitransmitter ezimbini okanye ezintathu zentambo okanye imiqondiso yomthombo wangoku, olu thintelo lokhuseleko luxhasa unxibelelwano oluya kwicala elinye lwesignali yedijithali yeHart ebekwe kwisignali ye-4~20mA kwaye inomsebenzi we-alamu yokuqhekeka kwentambo.

Le mveliso ifuna umbane ozimeleyo, onezixhobo zombane ezizimeleyo, izixhobo zokufaka, kunye nezixhobo zokukhupha.
