Txheej txheem cej luam
Cov ntaub ntawv nkag mus rau hauv thaj chaw muaj kev phom sij |
|
Lub teeb liab nkag | Hloov cov neeg sib cuag / cov hloov pauv sib thooj |
Lub zog ntawm lub sensor | Txog li 8V |
Kev hloov pauv tus nqi | ＜10kHz |
Cov yam ntxwv ntawm cov tswv yim / tso zis: |
|
Tam sim no ntawm qhov chaw nkag | > 2.1mA, qhov tso zis kaw, qhia ON; |
Cov zis feem ntau "Qhib" / "Kaw" Kev tswj hwm kev hloov pauv sib cuag | Thaum lub khawm K1-K4 nyob rau sab "ON", qhov tso zis relay yog "Normally closed", thaum lub khawm K1-K4 nyob rau sab "OFF", qhov tso zis relay yog "Normally open". |
Cov zis tawm hauv thaj chaw nyab xeeb |
|
Teeb liab tso zis | Kev xa xov |
Muaj peev xwm tiv tauj tau | 250VAC/2A, 30VDC/2A thaum raug cov khoom thauj resistive |
Lub sijhawm teb | 20ms |
Cov kev cai yooj yim |
|
Fais fab mov | 20 ~ 35V DC |
Kev siv hluav taws xob | ≤85mA (24V fais fab mov, thaum lub relay tiv tauj kaw) |
LED qhia | Ntsuab: Qhov qhia txog lub zog |
Cov ntsuas kub | Kub ua haujlwm: -20 ℃ ~ + 60 ℃, |
Cov av noo sib piv | 10% ~ 95% RH tsis muaj dej noo |
Lub zog rwb thaiv tsev | Nruab nrab ntawm sab muaj kev nyab xeeb thiab sab tsis muaj kev nyab xeeb (≥3000VAC/min); |
Kev tiv thaiv rwb thaiv tsev | ≥100MΩ (nruab nrab ntawm cov tswv yim / tso zis / fais fab mov) |
EMC | Raws li IEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
Cov kev cai ntawm cov hlau | Qhov seem hla ≥ 0.5mm²; Lub zog rwb thaiv tsev ≥ 500V |
Cov khoom siv hauv thaj teb siv tau | Cov khoom siv hauv teb xws li cov khoom sib cuag qhuav lossis NAMUR hom qhov hloov pauv qhov sib xws uas ua raws li tus qauv DIN19234 |
Qhov chaw teeb tsa | Nruab rau hauv thaj chaw muaj kev nyab xeeb, nws tuaj yeem txuas nrog cov cuab yeej kev nyab xeeb hauv thaj chaw txaus ntshai txog thaj chaw 0, IIC, Zone 20, thiab IIIC. |
| Daim ntawv pov thawj muaj kev nyab xeeb | |
| Lub cim tiv thaiv kev tawg | [Ex ia Ga] IIC [Ex ia Da] ⅢC |
| Tus qauv tiv thaiv kev tawg | GB/T 3836.1-2021 GB/T 3836.4-2021 |
| Cov Chaw Nres Tsheb 5-4, 5-6 2-1, 2-3 | Um: 250V AC/DC, Uo = 10.5V DC, Io = 15mA, Po = 39.4mW, Co = 1.7μF, Lo = 165mH. |
| Lub koom haum pov thawj | CQST (Tuam Tshoj Lub Chaw Saib Xyuas Kev Zoo thiab Kev Ntsuas rau Cov Khoom Siv Hluav Taws Xob Tiv Thaiv Kev Tawg) |
Lus Cim: 1. Lub hwj chim ntawm lub tsheb ciav hlau fais fab yog ib qho kev xaiv ua haujlwm. Cov neeg siv yuav tsum qhia meej hom kev muab hluav taws xob thaum xaj khoom. Thov saib daim ntawv txuas ntawm nplooj ntawv 89. Rau qhov hloov pauv sensor, yog tias xav tau LFD function, yuav tsum txuas nrog resistor.
