Thlennak luhternak transistor chuahnak signal isolator nih thlennak pehtlaihnak asiloah naihnak thlennak in luhnak signal kha thlennak in transistor chuahnak ah a thlen. Line palhnak hmuh khawhnak riantuannak cu module cunglei ah a ummi LED ceunak nih a langhter. Module i thlennak cu channel i a dirhmun le line palhnak hmuh khawhnak riantuannak a herh le herh lo thimnak caah hman a si.
Hi thilri hi amah tein thazaang pek a hau, cun thazaang peknak, luhnak le chuahnak terminal pawl cu an i then.
