PH D-22T F-2727
Txheej txheem cej luam
Kev tiv thaiv kev nyab xeeb ntawm kev tshawb pom sab: PHD-22TF-2727, digital input thiab output, dual input thiab dual tso zis.
Qhov thaiv kev sib cais tuaj yeem hloov pauv qhov sib thooj sib txuas thiab kev sib txuas lus hauv thaj chaw txaus ntshai rau lub teeb liab sib txuas thiab xa mus rau thaj chaw nyab xeeb.
Cov zis relay yog nruab nrog kev xaiv hloov ntawm "ON / OFF" qhov xwm txheej. Tsis tas li ntawd, muaj ib qho input signal short-circuit los yog qhib-circuit tswb qhia, lub Circuit Court muab hwj chim rau lub input sensor.
Cov khoom no xav tau 20-35VDC fais fab mov sab nraud.
Lub teeb liab teeb liab qhia tau teeb tsa hauv lub teeb liab thiab daj los qhia txog kev ua haujlwm ntawm cov zis relay, thaum lub tswb nrov ces lub teeb liab, thaum lub sijhawm ua haujlwm lub teeb daj.
* Tsheb npav fais fab mov, thov mus saib cov ntawv txuas ntxiv kom paub meej.
| Muab hluav taws xob | 20 ~ 35VDC, kev siv hluav taws xob |
| Input teeb liab | Hloov kev sib cuag / sib thooj hloov |
| Supply voltage los ntawm sensor sab ntawm qhov chaw | 8 V |
| Teeb liab input yam ntxwv | On-site input tam sim no:> 2.1mA, nws txhais tau tias ON; on-site input tam sim no: |
| Hloov hysteresis: 0.2ms | |
| Relay tso zis yam ntxwv | Lub sij hawm teb: 20ms, muaj peev xwm tsav tsheb: 250VAC / 2A, 30VDC / 2A nyob rau hauv qhov hnyav hnyav. |
| Tso zis "ON" / "OFF" hu rau conversion tswj | Thaum lub xov tooj hloov K1, K3 nyob rau ntawm "ON" sab, lub relay tso zis yog "OFF". |
| Thaum lub xov tooj hloov K1, K3 nyob rau ntawm "OFF" sab, lub relay tso zis yog "ON". | |
| Thaum lub dial hloov K2, K4 nyob rau sab "ON", lub Circuit Court xaiv qhia lub teeb liab relay tswb muaj nuj nqi. | |
| Qhia lub teeb tswb muaj nuj nqi | On-site input tam sim no> 7mA, luv-circuit tswb (SC), on-site input tam sim no |
| Rau kev hloov kev sib txuas lus, thaum lub disconnection nrhiav kom tau muaj nuj nqi, ib tug 10KΩ resistor yuav tsum tau kev cob cog rua thaum uas tig mus ntawm ob kawg ntawm lub hloov (Thov saib tus hloov hu II nyob rau hauv cov nram qab no wiring daim duab) | |
| Number of input thiab output | 2 input 2 tso zis |
| Siv tau cov khoom siv teb | Kev sib cuag qhuav lossis NAMUR sib thooj hloov raws li DIN 19234 tus qauv. |
| Kub parameter | Ua haujlwm kub: -20 ℃ - + 60 ℃, cia kub: -40 ℃ - + 80 ℃ |
| kwv tij huab cua humidity | 10% ~ 95% RH tsis muaj condensation |
| Dielectric zog | Nruab nrab ntawm sab hauv kev nyab xeeb thiab tsis muaj kev nyab xeeb sab hauv (≥ 3000VAC / min); nruab nrab ntawm cov khoom siv hluav taws xob thiab lub davhlau ya nyob twg tsis muaj kev nyab xeeb (≥ 1500VAC / min) |
| Rwb thaiv tsev tsis kam | ≥100MΩ (nruab nrab ntawm cov tswv yim / tso zis / fais fab mov) |
| Sab nraud qhov ntev | Thickness 12.5mm x dav 108mm x siab 118mm |
| Electromagnetic compatibility | Raws li IEC 61326-1 (GB / T 18268), IEC 61326-3-1 |
| Kev tawg pov thawj | [Exia Ga] IIC |
| Daim ntawv pov thawj kev nyab xeeb ua haujlwm | SIL3 raws li IEC 61508 EN 61511 tus qauv |
| Certification Lub Cev | CQST (Tuam Tshoj National Quality Supervision and Test Center for Explosion Protected Electrical Products) |
| Certified parameters (nruab nrab ntawm terminals 3-4,1-2) | Um = 250V Ua = 10.5V Kuv = 15 mA Co = 1.7μF Luas = 150 mH Po = 39.4 mW |
| Installation site Requirements | Nws tuaj yeem txuas nrog cov cuab yeej hauv 0 cheeb tsam nrog ⅡA, ⅡB, ⅡC roj txaus ntshai |
