A tlangpi in
H series hnulei vanlawng chiahnak ah a dang tein chiahmi himnak khamnak hna cu hmuh khawhnak lei ah: PHD-22HF-2727, digital luhternak le chuahnak, luhnak pahnih le chuahnak pahnih.
A dang tein chiahmi khamnak nih ttihnung hmun ah a naihnak thlennak le pehtlaihnak luhternak kha relay pehtlaihnak signal ah a thlen khawh i a himnak hmun ah a kuat khawh.
A chuakmi relay cu "ON/OFF" dirhmun thimnak thlennak he aa tlum. Cun, luhternak signal tawite-circuit asiloah on-circuit ralrin peknak hmelchunhnak a um, circuit nih luhternak sensor caah thazaang a pek.
Hi thilri nih hin amah tein mei a herh.
Signal dirhmun langhtertu cu a sen le a sen in ceunak in chiah a si i chuahmi relay riantuan ning a langhter, ralrin peknak caah a si tikah ceunak cu a sen, a ttha tein riantuan lio ah ceunak cu a sen.
