FAQ
Yuav ua li cas yog tias koj siv lub relay tsis tu ncua hauv lub tsheb?
Koj pheej hmoo ua tsis tau thaum ntxov. Cov relays tsis tu ncua tsis tuaj yeem tiv tshav kub, kev co, lossis ya raws hauv tsheb. Koj lub tsheb lub tshuab hluav taws xob yuav tsum tsis ua haujlwm lossis puas lawm.
Yuav ua li cas koj paub yog hais tias ib tug relay yog automotive qib?
Saib rau specs zoo li 12V lossis 24V coil voltage, siab tam sim no, thiab IP kev ntsuas (xws li IP67). Lub relay yuav tsum hais txog kev siv tsheb ntawm daim ntawv lo lossis cov ntaub ntawv.
Koj puas tuaj yeem sib pauv 4-pin relay rau 5-pin relay?
Koj tuaj yeem siv 5-pin relay nyob rau hauv qhov chaw ntawm 4-pin yog tias koj txuas tus pins txoj cai. Tus pin ntxiv cia koj hloov ntawm ob lub voj voog. Nco ntsoov xyuas koj daim duab kab hluav taws xob.
Vim li cas automotive relays tau tsim -hauv diodes?
Ua-hauv diodes tiv thaiv koj lub tsheb hluav taws xob los ntawm qhov hluav taws xob sib kis. Thaum koj tua lub relay, lub diode nres tam sim ntawd surges uas yuav ua rau puas rhiab qhov chaw.
Qhov twg koj feem ntau pom automotive relays nyob rau hauv ib lub tsheb?
Koj pom lawv hauv lub thawv fuse, hauv qab lub hood, lossis tom qab dashboards. Lawv tswj tej yam xws li lub taub hau, roj twj, thiab kiv cua.
