Txheej txheem cej luam
Kev tiv thaiv kev nyab xeeb nrog kev tiv thaiv kev tiv thaiv kev ua haujlwm ntawm kev hloov pauv input relay outputs, uas cais thiab xa tawm cov tswv yim tawm tswv yim los ntawm kev sib txuas lossis cov kev sib txuas sib txuas hauv cov chaw muaj kev puas tsuaj mus rau thaj tsam kev nyab xeeb nrog cov khoom tso tawm los ntawm kev tiv thaiv kev nyab xeeb. Kev kuaj xyuas kab yog ua tiav los ntawm LED nyob rau sab saum toj ntawm lub module. Lub dial hloov ntawm lub module yog siv los teem lub tswv yim thiab tso zis nyob rau hauv-theem los yog thim rov qab tswj, raws li zoo raws li pab kom los yog lov tes taw cov kab txhaum lub tswb ceeb toom muaj nuj nqi.
Cov khoom no xav tau lub zog ywj pheej, nrog cov khoom siv hluav taws xob cais tawm, cov tswv yim, thiab cov khoom siv tawm.
