Kubuka konkhe
Sithiyo sekuphepha lesihlukanisiwe eceleni kwekutfola: PHD-12TF-288, kufaka kwedijithali kanye nekukhipha, kufaka lokukodwa kanye nekukhipha lokubili.
^ Lesivimbelo lesihlukanisiwe singagucula switch yekusondzelana kanye nekufaka kwekutsintsana endzaweni leyingoti kube luphawu lwekuphuma lwe-transistor bese luyidlulisela endzaweni lephephile. I transistor lokukhipha emkhatsini ec ifakwe switch ukukhetha "sigaba inverted / sigaba evamile" , ngaphezu kwaloko, kukhona input signal circuit esifushane noma inkomba ye-alamu yesekhethi evulekile, lesisekethe inikeza input inzwa umphakelo amandla.
^ Lomkhicito udzinga umtfombo wamandla wangaphandle we-20-35VDC.
^ Inkomba yesimo sesiginali isethwe ekukhanyeni lokubovu nalokumtfubi kukhombisa simo sekusebenta se-relay yekukhipha, uma kungekwekwesabisa ke kukhanya kubovu, ngesikhatsi sekusebenta lokujwayelekile kukhanya kumtfubi.
* Kuphakelwa kwemandla ebhasi, sicela ubuke sithasiselo kute utfole imininingwane.
| Ivoltheji yekuphakela | ~ 35VDC, kusetjentiswa kwemandla |
| Siginali yekufaka | Shintja kuchumana/kusondzelana |
| Niketa ivoltheji kusuka eceleni kwenzwa kusayithi | 8V |
| Timphawu tekufaka tesiginali | On-site lokufaka zamanje:> 2.1mA, kusho ON; I-site yekufaka lamanje: |
| Shintsha kucindzeteleka: 0.2ms | |
| Timphawu te-transistor | NPN uhlobo transistor emitter noma umcokeleli kuvulekile kwesiyingi lokukhipha, umthamo wekushayela: lokukhipha lamanje ≤20mA (1.2KΩ), yangaphakathi esiphezulu samanje 100mA. Ifakwe sivikelo se-short-circuit yamanje |
| Kushintja kulawula emkhatsini wesigaba lesigucukile kanye nesigaba lesijwayelekile semiphumela ec . | Uma inkinobho yekushayela K1 ise "ON", umphumela we-transistor ec usesigabeni lesigucukile . |
| Uma inkinobho yekushaya K1 ise "OFF", lokukhipha kwe-transistor ec kusesigabeni lesijwayelekile . | |
| Uma i K2 ise . "ON", lesiyingi sitawukhetsa umsebenti we-alamu lekhombisa kukhanya lokubovu | |
| Kukhombisa umsebenti we-alamu yekukhanya | Insimu yekufaka nyalo >7mA, i-alamu yesifundza lesifishane (SC), i-alamu yekufaka endzaweni |
| Inombolo yetintfo letifakwako naletiphumako | 1 lokufakako 2 lokuphumako |
| Tintfo tekusebenta ensimini letisebentako | Kutsintsana lokomile noma kushintja kwekusondzelana kwe-NAMUR ngekuhambisana nelizinga le-DIN 19234. |
| Ipharamitha yekushisa | Lokushisa lokusebenta: -20 ° C ~ + 60 ° C, lokushisa kwekugcina: - 40 ° C ~ + 80 ° C |
| Umswakama wemoya | 10% ~ 95% RH ngaphandle kwekuncibilika |
| Emandla e-dielectric | Emkhatsini weluhlangotsi loluphephile ngaphakathi kanye neluhlangotsi lolungaphephile ngaphakathi (≥ 3000VAC / min); emkhatsini wekuphakelwa kwemandla kanye nesiphelo lesingaphephi ngekhatsi (≥ 1500VAC / min) |
| Kumelana nekuvikela | ≥100MΩ (emkhatsini wekufaka / lokukhiphako / kuphakelwa kwemandla) |

| Kuhambisana kwe-elekthromagnethi | Ngokusho IEC 61326-1 (GB / T 18268), IEC 61326-3-1. |
| Limaki lelingaqhumi | [Exia Ga]IIC |
| Sitifiketi sekuphepha lesisebentako | SIL3 ngekuya kwemazinga e-IEC 61508 EN 61511 |
| Umtimba Wesitifiketi | CQST (China Sikhungo Sekugadza Lizinga Nekuhlola Sive Semikhicito Yagezi Levikelwe Ekuqhumeni) |
| Emapharamitha lacinisekisiwe (emkhatsini wematheminali 3-4) | Um=250 V Uo=10.5V Mi=15mA Co=1.7μF Lo=150mH I-Po = 39.4mW |
| Tidzingo tendzawo yekufaka | Kungaxhunywa ngetintfo tekusebenta ku 0 zone nge IIA, IIB, IIC igesi leyingoti . |
