PHD-12TF-288
Overview
Isolated chengetedzo chipingamupinyi padivi rekuonekwa: PHD-12TF-288, dijitari kupinza uye kubuda, kupinza kamwe chete uye mbiri kuburitsa.
^ Iyo yakasarudzika chipingamupinyi inogona kushandura iyo yepedyo switch uye yekubata yekubatanidza munzvimbo ine njodzi kune transistor inobuda chiratidzo uye ichiendesa kunzvimbo yakachengeteka. Iyo inobuda transistor pakati pe ec inoshongedzerwa neanosarudza switch ye "inverted phase/normal phase" , mukuwedzera, kune yekuisa chiratidzo chepfupi chedunhu kana yakavhurika yedunhu alarm chiratidzo, dunhu rinopa yekupinza sensor magetsi.
^ Ichi chigadzirwa chinoda ekunze 20-35VDC magetsi.
^ Chiratidzo chechimiro chechiratidzo chakaiswa muchiedza chitsvuku uye chero kuratidza mamiriro ekushanda kweiyo relay inobuda, kana iri yekutyisa ipapo chiedza chitsvuku, panguva yekushanda kwemazuva ose chiedza chinenge chero.
* Bhazi magetsi emagetsi, ndapota ona appendix yeruzivo.
| Supply voltage | 20 ~ 35VDC, kushandiswa kwesimba |
| Input chiratidzo | Chinja kuonana/pedyo chinja |
| Supply voltage kubva kune sensor side pane saiti | 8V |
| Maitiro ekuisa masaini | Pa-saiti yekuisa ikozvino:> 2.1mA, zvinoreva ON; Pa-saiti yekuisa ikozvino: |
| Chinja hysteresis: 0.2ms | |
| Transistor kubuda maitiro | NPN mhando transistor emitter kana muunganidzi akavhurika redunhu goho, dhiraivha kugona: kubuda ikozvino ≤20mA (1.2KΩ), yemukati yakakura ikozvino 100mA. Yakashongedzerwa neshort-circuit current protection |
| Shandura kutonga pakati pechikamu chakatenderedzwa uye chakajairika chikamu chezvinobuda ec | Kana dial switch K1 iri pa "ON", iyo transistor inobuda ec iri muchikamu chakadzora |
| Kana dial switch K1 iri pa "OFF", iyo transistor inobuda ec iri muchikamu chakajairika | |
| Kana K2 iri pa "ON", circuti ichasarudza iyo dzvuku mwenje inoratidza alarm basa | |
| Kuratidza light alarm function | Munda wekuisa ikozvino> 7mA, pfupi-circuit alarm (SC), pane-saiti yekuisa ikozvino |
| Nhamba yekupinda uye kubuda | 1 kuisa 2 kubuda |
| Zvishandiso zvemumunda zvinoshanda | Dry kuonana kana NAMUR yepedyo switch zvinoenderana neDIN 19234 standard. |
| Tembiricha parameter | Kushanda tembiricha: -20 ℃~+60 ℃, tembiricha yekuchengetedza: -40 ℃~+80 ℃ |
| Hunyoro hwemhepo | 10% ~ 95% RH pasina condensation |
| Dielectric simba | Pakati pemukati yakachengeteka divi uye isiri-mukati yakachengeteka divi (≥ 3000VAC/min); pakati pemagetsi uye isiri-yakachengeteka terminal (≥ 1500VAC/min) |
| Insulation resistance | ≥100MΩ (pakati pekuisa/kubuda/magetsi) |
| Zviyero zvekunze | Ukobvu 12.5mm x upamhi 108mm x kukwirira 118mm |
| Electromagnetic kuenderana | Maererano neIEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
| Kuputika-chiratidzo chiratidzo | [Exia Ga]IIC |
| Functional safety certification | SIL3 zvinoenderana neIEC 61508 EN 61511 zviyero |
| Certification Body | CQST(China National Quality Supervision uye Test Center yeKuputika Kwakachengetedzwa Kwemagetsi Zvigadzirwa) |
| Certified parameters (pakati pematerminals 3-4) | Um=250V Uo=10.5V I=15mA Co=1.7μF Lo=150mH Po=39.4mW |
| Installation site Zvinodiwa | Inogona kubatanidzwa nezviridzwa munzvimbo ye0 ine ⅡA, ⅡB, ⅡC gasi rine njodzi. |
| MTBF | ≤100000h |
