Mawdaw relay ngu ai gaw, n-gun kaba hpe hkang lu na matu, n-gun kaji hpe lang nna bungli galaw ai electronic hkang ai jak langai mi re. Shi a madung bungli ni gaw, shi hkum shi gram lajang ai, shim lum ai hku makawp maga ai, circuit galai shai ai, galai shai ai lam ni rai nga ai. Mawdaw relay langai hkrat sum mat yang, mawdaw a bungli nkau mi gaw hkrak n galaw lu na re.
Mawdaw relay langai a masa hpe chyam yu na matu lawu na ladat ni hpe lang mai ai:
Relay ngu ai gaw, masat da ai input quantity hpe jaw nna, aten law law hkam la lu ai majaw, wan pru ai circuit hta hkang ai quantity hpe tau hkrau masat da ai lahkam galai shai wa hkra galaw lu ai wan n-gun hpe hkang ai jak langai mi re. Input gaw madang langai ngai de hkrat sum mat nna, aten galu hkra nga yang, system gaw shawng na masa de bai nhtang wa na re.
1. Relay n-gun rawng ai (sh) n-gun rawng ai hpe hkam sha na matu stethoscope (sh) na a lata hpe lang u. Rai yang, madung hku nna hkrak hkrak bungli galaw nga ai.
2. Relay a coil n-gun hpe shadawn na matu digital multimeter lang na. Typically 2kΩ a lawu kaw rai ra ai.
3. Power off galaw da ai shaloi, n-gun n-gun hpe shadawn yu u. Resistance gaw zero hte ni ai (sh) grai n law ai rai ra ai.
Ndai chyam dinglik ladat ni hpe hpawng de dat yang, mawdaw relay a masa hpe hkrak chye lu ai. Tatut hta, masa lam ni hpe madung tawn nna, hkum tsup ai hku sawk sagawn ai lam galaw ra ai, dai gaw, shut ai hku dawdan ai majaw sum mat ai lam ni hpe koi lu na matu rai nga ai.
