Ukuhlolisisa
I-H series backplane mounting isolated safety barriers at detection side: PHD-12HF-277, digital input and output, single input and dual output.
Isithiyo esihlukanisiweko singatjhugulula iswitjhi yokutjhidelana nokufaka kokuthintana endaweni eyingozi kube siginali yokuthintana ye-relay bese idlulisela endaweni ephephileko.
I-relay yokukhipha ifakwe iswitjhi yokukhetha "VULA/VALA" ubujamo. Ukungezelela, kunesibonakaliso sokufaka esifitjhani namkha esivulekileko se-alamu, isekhethi inikela amandla wesensa yokufaka.
Umkhiqizo lo udinga umthombo wamandla ozijameleko.
Isitjengiso sesimo sesiginali sisethwe emkhanyweni obomvu nophuzi ukutjengisa ubujamo bokusebenza kwe-relay yokukhipha, lokha nayithusako khona-ke ukukhanya kuba bomvu, ngesikhathi sokusebenza okujayelekileko ukukhanya kuba mthubi.
| Ivoltheji yokuphakela | 20~35VDC, ukusetjenziswa kwamandla |
| Isiginali yokufaka | Tjhugulula ukuthintana nofana amaswitjhi wokusondelana (NAMUR) |
| Ukuphakela ivoltheji yesensa endaweni | 8V |
| Ubunjalo bokufaka isiginali | Umtjhini wokufaka endaweni: >2.1mA, utjengisa bona uvuliwe; Umtjhini wokufaka endaweni: |
| Umphumela endaweni ephephileko | Isikhathi sokuphendula: 20ms, ikghono lokutjhayela: 250VAC/2A, 30VDC/2A ngaphasi komthwalo oqinileko |
Okuphumako kuvamise ukuba “Vula”/“Vala” | Lokha iswitjhi yokudayela i-K1, i-K3 isehlangothini elithi "VULWE", ukuphuma kwe-relay ku-"VALI" |
| Lokha iswitjhi yokudayela i-K1, i-K3 isehlangothini elithi "OFF", ukuphuma kwe-relay "KUVULWA" | |
| Lokha iswitjhi yokudayela i-K2, K4 isehlangothini elithi "ON", isekhethi ikhetha ukutjengisa umsebenzi we-alamu ye-LFD yokukhanya okubomvu | |
| I-LFD | Umtjhini wokufaka endaweni>7mA, i-alamu ye-short-circuit (SC), i-alamu yokufaka endaweni |
| Ukungeniswa kokuthintana kweswitjhi, lokha nakutlhogeka umsebenzi wokuthola ukuvalwa, i-resistor ye-22KΩ kufanele ixhunywe ngokufana emaphethelweni womabili weswitjhi (Sibawa uqale iswitjhi yokuthintana II emfanekisweni weentambo ongezansi) | |
| Inomboro yokufaka nokukhipha | 1 okufakwako 2 okuphumako |
| Iinsetjenziswa ezisebenzako | I-Dry contact nofana i-NAMUR proximity switch ngokuya nge-DIN 19234 standard |
| Ipharamitha yokutjhisa | Izinga lokutjhisa lokusebenza: -20°C~+60°C, izinga lokutjhisa lokugcina: -40°C~+80°C |
| Umswakama ohlobene | 10%~95% RH akukho ukutjhisa |
| Amandla we-dielectric | Phakathi kwehlangothi eliphephileko nelingaphephileko (≥3000VAC/min); hlangana nokuphakelwa kwamandla netheminali engaphephiko (≥1500VAC/min) |
| Ukujamelana nokuvikela | ≥100MΩ (phakathi kokufaka/ukukhipha/ukuphakelwa kwamandla) |
| Ubukhulu | Ubukhulu 15.8mm * ububanzi 104.8mm * ukuphakama 116.1mm |
| Ukukhambisana kwe-elekthromagnethi | Ngokuya nge-IEC 61326-1 (GB/T 18268), i-IEC 61326-3-1 |
| Itshwayo elivikela ukuqhuma | [Exia Ga]IIC, [Exia Da]IIIC |
| Umzimba wesitifiketi | I-CQST (i-China National Quality Supervision and Test Center of Explosion Protected Electrical Products) |
| Imingcele eqinisekisiweko (hlangana namatheminali 1-2) | Um:250VAC/DC,Uo=10.5VDC,Io=14mA, Po=37mW,Co=2.4μF,Lo=165mH. |
| Iimfuneko zendawo yokufaka | Ingahlanganiswa namathulusi ku-0 zone nge IIA, IIB, IIC irhasi eyingozi Ifakwe endaweni ephephileko, ingahlanganiswa namathulusi wokuphepha wangaphakathi eendaweni eziyingozi ukuya ku-Zone 0, IIC, Zone 20, kanye ne-IIIC |
| MTBF | ≤100000h |
