Ib qho opto-isolator yog ib qho khoom siv hluav taws xob uas hloov hluav taws xob teeb liab ntawm ob qhov sib cais los ntawm kev siv lub teeb. Opto-isolators tiv thaiv qhov hluav taws xob siab los ntawm kev cuam tshuam rau lub kaw lus tau txais lub teeb liab.
Lub hom phiaj ntawm kev cais opto yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm opto-isolator yog txhawm rau thaiv cov hluav taws xob siab thiab qhov hluav taws xob hloov pauv, kom qhov nce siab hauv ib feem ntawm lub kaw lus yuav tsis cuam tshuam lossis rhuav tshem lwm tus. qhov chaw.
Dab tsi yog opto cais relay?
Optically-isolated relays yog tus yam ntxwv los ntawm kev siv lub teeb emitting diode (LED) ntawm lawv cov tswv yim sab, MOSFETs ntawm cov zis sab thiab ib qho ntawm cov duab sensors nyob nruab nrab ntawm. Hauv kev ua haujlwm, tam sim no ntws los ntawm LED, uas tom qab ntawd tawm lub teeb.
opto tso zis yog dab tsi?
Ib optocoupler (tseem hu ua optoisolator) yog semiconductor ntaus ntawv uas tso cai rau lub teeb liab hluav taws xob xa mus ntawm ob lub voj voog sib cais. … Lub photosensor yog lub tso zis hluav taws xob uas kuaj pom lub teeb thiab nyob ntawm seb hom tso zis hluav taws xob, cov zis yuav yog AC lossis DC.
Yuav ua li cas opto coupler muab kev cais tawm?
Ib qho optocoupler ua tiav qhov kev sib cais no los ntawm coj cov cim qhia tias nws tau txais ntawm nws cov tswv yim thiab xa cov teeb liab siv lub teeb rau nws cov zis. Lub optocoupler txhais cov teeb liab ntawm nws cov tswv yim rau hauv lub teeb infrared siv lub teeb infrared emitting diode (LED).
