Isishwankathelo
Umqobo wokhuseleko olulodwa kwicala lokufumanisa: PHD-12TF-288, igalelo ledijithali kunye nemveliso, igalelo elinye kunye nemveliso emibini.
^ Umqobo osecaleni unokuguqula umtshintshi osondeleyo kunye negalelo loqhagamshelwano kwindawo enobungozi kwi-transistor output signal kwaye uyithumele kwindawo ekhuselekileyo. I-transistor ephumayo phakathi kwe-ec ixhotyiswe ngenguqu yokukhetha "isigaba se-inverted / isigaba esiqhelekileyo" , ukongeza, kukho i-input signal short circuit okanye isalathisi se-alarm yesiphaluka evulekileyo, isiphaluka sibonelela nge-input sensor power supply.
^ Le mveliso idinga umbane wangaphandle we-20-35VDC.
^ Isalathisi sesimo somqondiso sisekwe ekukhanyeni okubomvu kunye nokutyheli ukubonisa isimo sokusebenza kwe-relay ephumayo, xa iyinto eyothusayo ke ukukhanya kubomvu, ngexesha lokusebenza okuqhelekileyo ukukhanya kuphuzi.
* Umbane webhasi, nceda ubone isihlomelo ngeenkcukacha.
| Unikezelo lombane | I-20 ~ 35VDC, ukusetyenziswa kwamandla |
| Uphawu longeniso | Tshintshela umfowunelwa/ukusondela |

| Iimpawu zokungenisa umqondiso | Igalelo langoku kwisiza:>2.1mA, lithetha UKUVULA; Igalelo langoku kwisiza: |
| Tshintsha i-hysteresis: 0.2ms | |
| Iimpawu zemveliso yeTransistor | I-NPN yohlobo lwe-transistor emitter okanye umqokeleli ovulekileyo wesiphaluka imveliso, umthamo we-drive: i-output current ≤20mA (1.2KΩ), i-internal maximum current 100mA. Ixhotyiswe ngokhuseleko lwangoku lwesiphaluka esifutshane |
| Ukutshintsha ulawulo phakathi kwesigaba esijikelelweyo kunye nesigaba esiqhelekileyo seziphumo ec | Xa ifowuni yokucofa i-K1 ise-"ON", i-transistor output ec ikwinqanaba eliguqulweyo |
| Xa ukucofa ifowuni K1 iku "OFF", i-transistor output ec ikwinqanaba eliqhelekileyo | |
| Xa ikwi K2 "ON", iseti iya kukhetha isibane esibomvu se-alarm function | |
| Ibonisa umsebenzi we-alam wokukhanya | Igalelo lentsimi yangoku> 7mA, i-alarm ye-short-circuit (SC), i-on-site input current |
| Inani legalelo kunye nemveliso | Igalelo eli-1 2 imveliso |
| Izixhobo zentsimi ezisebenzayo | Umnxeba owomileyo okanye i-NAMUR yokutshintsha ukusondela ngokuhambelana ne-DIN 19234 standard. |
| Iparameter yobushushu | Ubushushu bokusebenza: -20℃~+60℃, ubushushu bokugcina:-40 ℃~+80℃ |
| Ukufuma komoya okunxulumeneyo | I-10% ~ 95% RH ngaphandle kokudibanisa |
| Amandla e-Dielectric | Phakathi kwecala elikhuselekileyo langaphakathi kunye necala elingakhuselekanga (≥ 3000VAC / min); phakathi konikezelo lwamandla kunye netheminali engeyoyangaphakathi ekhuselekileyo (≥ 1500VAC/min) |
| Ukumelana ne-insulation | ≥100MΩ (phakathi kwegalelo/imveliso/ubonelelo lwamandla) |
| Imilinganiselo yangaphandle | Ukutyeba 12.5mm x ububanzi 108mm x ukuphakama 118mm |
| Ukuhambelana kwe-electromagnetic | Ngokutsho kwe-IEC 61326-1(GB/T 18268), IEC 61326-3-1 |
| Uphawu olunobungqina bokudubula | [Exia Ga]IIC |
| Isiqinisekiso sokhuseleko esisebenzayo | I-SIL3 ngokwemigangatho ye-IEC 61508 EN 61511 |
| IZiko lesiQinisekiso | I-CQST(iZiko leSizwe lokuJonga uMgangatho kunye neZiko loVavanyo lokuPhuma kweeMveliso zoMbane eziKhuselweyo) |
| Iiparamitha eziqinisekisiweyo (phakathi kweetheminali 3-4) | Um=250V Uo=10.5V I=15mA Co=1.7μF Lo=150mH Po=39.4mW |
| IiMfuno zesiza sokufakela | Inokudityaniswa nezixhobo kwi-0 zone nge-ⅡA, ⅡB, ⅡC igesi eyingozi |
