I-PH D-22T F-2727
Uhlolojikelele
Isithiyo sokuphepha esisodwa ohlangothini lokutholwa: PHD-22TF-2727, okokufaka kwedijithali nokuphumayo, okokufaka okukabili kanye nokuphuma kabili.
Umgoqo ohlukanisiwe ungaguqula iswishi ye-proximity kanye nokokufaka kokuxhumana endaweni eyingozi kusignali yokuxhumana edluliselwe futhi uyidlulisele endaweni ephephile.
I-relay ephumayo ifakwe inkinobho yokukhetha yesimo esithi "VULIWE/CIMILE". Ngaphezu kwalokho, kukhona isignali yokufaka i-short-circuit noma inkomba ye-alamu evulekile, isifunda sinikeza amandla enzwa yokufaka.
Lo mkhiqizo udinga ugesi wangaphandle we-20-35VDC.
Inkomba yesimo sesignali isethwe ekukhanyeni okubomvu nokuphuzi ukuze ibonise isimo sokusebenza se-relay ephumayo, uma isethuse bese ukukhanya kuba bomvu, ngesikhathi sokusebenza okuvamile ukukhanya kubaphuzi.
* Ukunikezwa kwamandla ebhasi, sicela ubone isithasiselo ukuze uthole imininingwane.
| I-voltage yokuhlinzeka | 20~35VDC, ukusetshenziswa kwamandla |
| Isignali yokokufaka | Shintsha othintana naye/ukusondela |
| Hambisa i-voltage kusuka ohlangothini lwenzwa esizeni | 8V |
| Izici zokufaka isignali | Okokufaka okusendaweni: >2.1mA, kusho VULIWE; okokufaka okusendaweni: |
| Shintsha i-hysteresis: 0.2ms | |
| Izici zokukhipha edluliselwe | Isikhathi sokuphendula: 20ms, umthamo wokushayela: 250VAC/2A, 30VDC/2A ngaphansi komthwalo ophikisayo. |
| Okukhiphayo "VULIWE"/"VALIWE" isilawuli sokuguqula othintana naye | Uma inkinobho yokudayela i-K1, i-K3 iseceleni kokuthi "ON", okukhiphayo kokudluliselana "KUVALIWE". |
| Uma inkinobho yokudayela i-K1, i-K3 isehlangothini elithi "VALIWE", okukhiphayo ku-relay "KUVULIWE". | |
| Lapho inkinobho yokudayela i-K2, i-K4 iseceleni kokuthi "ON", isekethe ikhetha okubonisa umsebenzi we-alamu yokudlulisa ukukhanya okubomvu. | |
| Ibonisa umsebenzi we-alamu okhanyayo | Okokufaka okusendaweni > 7mA, i-alamu ye-short-circuit (SC), yamanje okokufaka endaweni |
| Okokufaka kothintana naye okushintshayo, lapho umsebenzi wokuthola ukunqanyulwa udingeka, isimelaphi esingu-10KΩ kufanele sixhunywe ngokuhambisana kuzo zombili iziphetho zeswishi (Sicela ubone othintana naye weswishi II kumdwebo wezintambo ongezansi) | |
| Inombolo yokokufaka nokuphumayo | 2 okokufaka 2 okukhiphayo |
| Imishini yasensimini esebenzayo | Oxhumene naye okomile noma ukushintsha kwe-NAMUR okusondele ngokuhambisana nezinga le-DIN 19234. |
| Ipharamitha yezinga lokushisa | Izinga lokushisa lokusebenza: -20 ℃- +60 ℃, izinga lokushisa lokulondoloza: -40 ℃- +80 ℃ |
| Umswakama womoya ohlobene | 10%~95%RH ngaphandle kokujiya |
| Amandla e-Dielectric | Phakathi kohlangothi oluphephile ngaphakathi kanye nohlangothi olungaphephile ngaphakathi (≥ 3000VAC/min); phakathi kokunikezwa kwamandla kanye netheminali engaphephile ngaphakathi (≥ 1500VAC/min) |
| Ukumelana ne-insulation | ≥100MΩ (phakathi kokufaka/okuphumayo/ukunikezwa kwamandla) |
