PHD-11TD-21

Kubuka konkhe

Sithiyo sekuphepha lesihlukanisiwe eceleni kwekutfola: PHD-11TD-21, kufaka kwe-analog kanye nekukhipha, kufaka lokukodwa kanye nekukhipha lokukodwa.

^ Lesivimbelo lesihlukanisiwe singahlukanisa futsi sidlulisele luphawu lwe-4 ~ 20mA noma luphawu lwe-DC 4 ~ 20 mA lolukhicitwa ngumdluliseli endzaweni leyingoti kuya endzaweni lephephile. Uma umdluliseli luhlelo lwetintambo letimbili noma letintsatfu, sivimbo sekuphepha siniketa emandla kumdluliseli.

^ Lomkhicito udzinga umtfombo wamandla wangaphandle we-20-35VDC.

^ Lomkhicito usekela luphawu lwe-HART kanye ne-alamu yekuyekeliswa.

* Caphela: Uma udzinga letinye tilinganiso talomkhicito, sicela utsintse ukwesekwa kwetfu kwebuchwepheshe. Uma lokukhiphako kunguletinye tilinganiso, kukhonjiswa yinombolo 9, futsi imikhawulo letsite ikhonjiswa ngemuva kwenombolo yemodeli.

I-analog input ehlukanisiwe sivimbelo sekuphepha inikeza emandla ehlukanisiwekuphakelwa kwetintsambo letimbili - kanye naletintsatfu etindzaweni letiyingoti.

Le 4 ~ 20mA signal leyakhiwa ngumdluliseli noma umtfombo wamanje idluliselwa kusuka endzaweni leyingoti kuya endzaweni lephephile lokukhiphako, ngaleyo ndlela kushayela umtfwalo endzaweni lephephile. Kubabili - noma labatsatfu labadlulisela tintsambo noma timphawu temtfombo wamanje, lesivimbelo sekuphepha sisekela kukhulumisana lokubili kwesiginali yedijithali yeHart lefakwe ngetulu kwesiginali ye-4 ~ 20mA futsi inemsebenti we-alamu yekuphuka kwetintambo.

Lomkhicito udzinga kuphakelwa kwemandla lokutimele, ngekuphakelwa kwemandla lokuhlukile, kufaka, kanye netiphetho tekukhipha.
