Analog luhtermi a dang tein chiahmi himnak khamnak nih ttihnung hmun ah hri pahnih le pathum caah a dang tein mei a pek. Transmitter asiloah current source nih a chuahmi 4~20mA signal cu tihnung hmun in a himnak hmun chuahnak ah a kuat, cucaah a himnak hmun ah thilrit a kalpi. Wire kuatnak pahnih asiloah pathum asiloah a tu lio thawngthanhnak caah, hi himnak khamnak nih hin 4~20mA signal cung ah chiahmi Hart digital signal kha lam hnih in pehtlaihnak a bawmh i hri a rawhnak ralrin peknak rian a ngei. Hi thilri nih hin a dang tein mei a herh, a dang tein mei a herh, luhternak le chuahnak terminal hna he.
