Mobili relay ye fɛnba ye min nafa ka bon kosɛbɛ mobili ka ciriw kɔnɔ. A ka baara koloma ye ka kurunba dɔ Kɔrɔsi ni kurunba fitinin ye, ka se ka sɛrɛkili sɛgɛsɛgɛli ni lakanani sɔrɔ otomatiki la. Kɛrɛnkɛrɛnnenya la, ni donna hakɛ (i n’a fɔ tension, current, temperature, a ɲɔgɔnnaw) sera dancɛ dɔ ma min latigɛra ka kɔn, relay kɔnɔna kuran-magnetiki-sitɛmu bɛ contacts (kontakw) bila ka da walima ka da, o la, a bɛ circuit principal (kurunba) ka on/off cogoya kɔlɔsi. O jogo in b’a to a bɛ se ka baara caman kɛ mobili ɛntɛrinɛti sitɛmuw kɔnɔ:
Circuit Control and Switching: Mobili relayw bɛ kɛ kosɛbɛ motɛriw ɲɛminɛyɔrɔw (ECU), yeelenbɔlanw, fiɲɛbɔlanw, fiɲɛbɔlanw ani ko wɛrɛw la. Misali la, ni bolifɛntigi ye yeelenba dɔw da, relay bɛ kuran taamasiyɛn barikama dɔ sɔrɔ ka bɔ switch (switch) la, o bɛ kɔnɔna kuran-magnetiki bobine lawuli ka fanga di, o bɛ kɛ sababu ye ka fɛnw datugu, o cogo la, a bɛ ɲɛfɛlan ciriw siri ɲɔgɔn na ani ka lanpanw mana. Nin "small-scale control of large-scale" dilancogo in bɛ a yɛrɛ tanga kuran caman ma ka tɛmɛ switch fɛ k'a ɲɛsin switch ma, ka minɛnw ka ɲɛnamaya janya.
Doni caman lakanani ani lakanani danfara: Ni motɛrɛ daminɛna walima ni a kɛra sɛrɛkili surun ye, relay bɛ se ka minɛnw tiɲɛni bali ni a ye ciriw tigɛ joona. Misali la, starter relay bɛ tigɛ a yɛrɛma motɛri daminɛ kɔfɛ, o bɛ starter motɛri bali ka sumaya kojugu ka da a baara waati jan kan. O waati kelen na, relayw bɛ sɛrɛkiliw bɔ ɲɔgɔn na minnu ka teli ka wuli ka bɔ ɲɔgɔn na ka bɔ tension dɔgɔmanninw ka kunnafonidilanw na, o bɛ baarakɛlaw ka lakana sabati.
Logic Operations and Signal Amplification: Bi mobili bɛ baara kɛ ni Electronic Control Units (ECU) caman ye, ani relays bɛ se ka logique controle multi-condition. Misali la, fiɲɛbɔlanw bɛ a ɲini ka ɲɔgɔnkanu dɔnni taamasiɲɛw ni mobili teliya taamasiɲɛw dɔn waati kelen na; relais bɛ baara kɛ ni hakilina jɛlenw ye walasa k’a dɔn ni u bɛna fiɲɛbɔlan daminɛ, k’a lajɛ ko lakanani minɛn bɛ baara kɛ dɔrɔn cogoya kɛrɛnkɛrɛnnenw na.
Multi-Signal Distribution: Body Control Module (BCM) kɔnɔ, relay kelen bɛ se ka doni caman kɔlɔsi. Misali la, relay kelen bɛ se ka kɔnɔna kalanlanw, da yeelenw ani bagasi lanpanw ɲɛnabɔ waati kelen na, ka wiriyaw labɛncogo nɔgɔya ani ka dɔ bɔ dɛsɛ hakɛw la.
