Kuj tseem siv rau ntawm cov hlua, lub qhov rooj, cov winches, cov daus, cov cua nkag/tso pa tawm, tsheb tawm thiab lwm yam thim rov qab daim ntawv thov. Module tau thim rov qab cov kev taw qhia ntawm lub tshuab thaum qhov tsim nyog tswj hwm lub zog tau ua haujlwm nrog lub plawv dhia los ntawm kev hloov pauv.

Hauv qhov no, qhov kev xa rov qab ua haujlwm li cas?

A thim rov qab hwj chim relay pab saib xyuas lub zog hauv lub tshuab hluav taws xob, nws kuaj pom a thim rov qab lub zog muaj zog, thiab relay tam sim ntawd tshem tawm cov kev sib txuas rau cov khoom siv hluav taws xob sib txuas lossis lwm qhov chaw siv hluav taws xob, yog li tiv thaiv lub tshuab hluav taws xob los ntawm kev puas tsuaj.

Ib sab saum toj no, DPDT relay ua haujlwm li cas? DPDT sawv rau ob-ncej ob-pov relay uas yog cov khoom siv hluav taws xob siv los cais ob lub voj voog hluav taws xob thiab txuas lawv sib nqus. Lawv feem ntau siv los cuam tshuam cov hluav taws xob hluav taws xob, uas ua haujlwm ntawm qhov hluav taws xob qis rau hluav taws xob hluav taws xob uas ua haujlwm ntawm qhov hluav taws xob siab.

Ib tus kuj tseem yuav nug, dab tsi yog qhov rov qab solenoid?

Reversing Solenoids . Kev sib xyaw ntawm ob solenoids hauv ib pob los txo tus nqi thiab ua kom txuag tau qhov chaw ntau tshaj plaws thaum tseem muab cov xov hluav taws xob yooj yim dua. Ob qho tseem ceeb solenoids muab lub zog ua kom muaj zog rau lub cav hlau nplaum ruaj khov, Qhia Ntxiv.

Vim li cas thim rov qab fais fab siv?

Rov qab fais fab relay yog kev tiv thaiv kev taw qhia relay , uas tiv thaiv rov ntws ntawm hwj chim hauv thim rov qab kev taw qhia. A relay yog siv los tiv thaiv rov ntws ntawm hwj chim los ntawm lub tshuab hluav taws xob nquag mus rau cov khoom siv hluav taws xob lossis lwm lub tshuab hluav taws xob thaum lub tshuab hluav taws xob ua haujlwm ua ke nrog lwm lub tshuab hluav taws xob lossis hluav taws xob.
