Stebėjimo relės - tai relės, kurios, aptikus gedimą, įjungia grandinės pertraukiklį. Relė - tai elektra valdomas jungiklis, naudojamas grandinės maitinimui įjungti arba išjungti.
Stebėjimo relės yra sudėtingesnės už įprastas reles, nes jos turi reguliuojamas veikimo sąlygas, o įprastos relės persijungia pagal fiksuotą ribą. Jos matuoja tam tikrą parametrą, pavyzdžiui, įtampą ar temperatūr...
