Txheej txheem cej luam
Lub switching input transistor output signal isolator hloov cov input signal los ntawm qhov switch contact lossis proximity switch mus rau hauv transistor output los ntawm kev cais tawm. Lub teeb LED nyob rau sab saum toj ntawm lub module qhia txog kev ua haujlwm ntawm kev kuaj pom kab txhaum. Lub switch ntawm lub module siv los xaiv theem ntawm cov channel thiab seb puas xav tau kev ua haujlwm ntawm kev kuaj pom kab txhaum.
Cov khoom no yuav tsum tau siv hluav taws xob ntawm nws tus kheej, thiab lub hwj chim muab hluav taws xob, cov tswv yim thiab cov zis tawm raug cais tawm.
| Cov tswv yim | |
| Lub teeb liab nkag | Hloov cov neeg sib cuag / cov hloov pauv sib thooj |
| Lub zog ntawm lub sensor | Txog li 8V |
| Qhov ntau zaus ntawm cov tswv yim | ≤5kHz |
| Cov yam ntxwv ntawm cov tswv yim / tso zis: | |
| Tam sim no ntawm qhov chaw nkag | > 2.1mA, qhov tso zis kaw, qhia ON; |
| Thaum | |
| Kev tswj hwm hloov pauv ntawm theem tig rov qab thiab theem ib txwm ntawm cov zis ec | Thaum lub khawm hloov K1, K3 nyob rau sab "ON", cov zis transistor ec nyob rau hauv theem tig rov qab. |
| Thaum lub khawm hloov K1, K3 nyob rau sab "OFF", qhov tso zis transistor ec nyob rau theem ib txwm. | |
| Thaum lub khawm K2, K4 nyob rau sab "ON", lub voj voog xaiv qhia txog lub teeb liab LFD lub tswb ceeb toom. | |
| Tso zis | |
| Teeb liab tso zis | Transistor |
| Cov yam ntxwv ntawm cov zis | NPN hom transistor emitter lossis collector qhib qhov hluav taws xob tso zis |
| Muaj peev xwm tsav tsheb | Tam sim no tso zis ≤ 20mA (1.2k Ω), siab tshaj plaws sab hauv tam sim no 100mA, nruab nrog kev tiv thaiv tam sim no luv luv |
| Cov kev cai yooj yim | |
| Fais fab mov | 20 ~ 35VDC |
| Kev siv hluav taws xob | |
| LED qhia | Ntsuab: Qhov qhia txog lub zog |
| Daj: Cov zis transistor hauv lub xeev ua haujlwm ib txwm | |
| Liab: qhia txog LFD, lub tswb ceeb toom txog kab txhaum | |
| Cov ntsuas kub | Kub ua haujlwm: -20 ℃ ~ + 60 ℃, |
| Kub cia: -40 ℃ ~ + 80 ℃ | |
| Cov av noo sib piv | 10% ~ 95% RH tsis muaj dej noo |
| Lub zog rwb thaiv tsev | ≥2000VAC/min (nruab nrab ntawm cov tswv yim/tso zis/hwj chim muab lus) |
| Kev tiv thaiv rwb thaiv tsev | 100MΩ (500VDC) (ntawm cov tswv yim / tso zis / fais fab mov) |
| Kev sib raug zoo ntawm hluav taws xob | GB/T 18268 (IEC 61326-1) |
| MTBF | 80000 teev |
| 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 |
Lus Cim: 1. PHG-12TF-288 tsis suav nrog qhov nkag 2.
2. 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.
Kev Tshawb Pom Kab Txhaum
Cov neeg siv tuaj yeem xaiv sab "ON" ntawm lub qhov hloov ntawm sab saum toj ntawm lub module kom ua haujlwm nrhiav qhov txhaum thiab qhia lub tswb los ntawm lub teeb liab LED. Tam sim no nkag mus rau hauv qhov chaw> 7mA, lub tswb luv luv (SC); Tam sim no nkag mus rau hauv qhov chaw
