PHD-11HD-21
Kubuka konkhe
Sithiyo sekuphepha lesihlukanisiwe eceleni kwekutfola: PHD-11HD-21, kufaka kanye nekukhipha kwe-analog, 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. Lo mkhicito udzinga umphakelo wemandla lotimele. Lomkhicito usekela siginali ye-HART kanye ne-alamu yekuyekeliswa.
Emapharamitha lamakhulu ebuchwepheshe |
|
Linani letiteshi: | lokufaka lokukodwa kanye nekuphuma lokukodwa |
Kuphakelwa kwemandla: |
|
Ivoltheji yekuniketa gezi: | ~ 35V DC, kusetjentiswa kwemandla cishe 1.5W (24V DC, lokukhipha 20mA) |
Kuvikelwa kwemandla: | kuvikelwa kwemandla lokubuyela emuva |
Lokufakwako lokuyingoti: |
|
Siginali yekufaka: | 2-intambo, 3-intambo noma umtfombo wamanje 4-20mA (HART). |
Ivoltheji yekusabalalisa: | ivoltheji levulekile-yesiyingi ≤28V, ivolthi lekhiphako ≥15.5V uma lesiyingi singu-20mA. |
Umphumela weluhlangotsi lwekuphepha: |

Inkomba ye-LED: | Luhlata—lolukhombisa emandla |
Sikhatsi sekuphendvula: | 2ms kuya ku 90% welinani lekugcina |
Emandla ekuvikela: | siphetfo lesiphephile ngaphakathi kanye nekuphela lokungaphephi ngaphakathi (≥3000V AC / min); kuphakelwa kwemandla kanye nekuphela lokungaphephi emkhatsini we (≥1500V AC/min) |
Kumelana nekuvikela: | ≥100MΩ (kufaka/kukhipha/kuphakelwa kwemandla emkhatsini) |
Kuhambisana kwe-electromagnetic: | ngekuhambisana ne-IEC 61326-1 (GB / T 18268), IEC 61326-3-1. |
Emadivayisi lasebentako: | Umdluliseli wetintambo letingu-2, umdluliseli wetintambo letingu-3, luphawu lwemtfombo wamanje. |
Indzawo yekufaka: | ingahlanganiswa ne IIA, IIB, IIC igesi leyingoti, tintfo tekusebenta letiphephile ngekwemvelo eNdzaweni 0. |
