Ma relay amagalimoto ndi ma relay omwe amagwiritsidwa ntchito pamagalimoto. Ma relay awa amasintha mphamvu zonyamula katundu wambiri ndipo amakhala ndi kugwedezeka kwakukulu komanso kukana kugwedezeka.
Mphamvu zamagetsi zamagalimoto nthawi zambiri zimakhala 12V, ndipo voteji ya coil nthawi zambiri imapangidwa kuti ikhale 12V. Chifukwa cha mphamvu ya batri ndi kusakhazikika kwamagetsi; zovuta zachilengedwe; ndi kukoka pang'ono-magetsi (V Ochepera kapena ofanana ndi 60% VH, ovoteledwa voteji); coil overvoltage amaloledwa kufika 1.5VH. Kugwiritsa ntchito mphamvu ya ma coil ndikokwera kwambiri, nthawi zambiri 1.6-2W, zomwe zimapangitsa kuti kutentha kukweze kwambiri. Zofunikira zachilengedwe ndizovuta kwambiri: mu chipinda cha injini, kutentha kozungulira ndi -40 digiri mpaka 125 digiri; m'malo ena, osiyanasiyana ndi -40 digiri mpaka 85 digiri. Zolumikizira zomwe zimagwiritsidwa ntchito m'chipinda cha injini ziyenera kupirira mchenga, madzi, mchere ndi mafuta; kugwedezeka ndi kugwedezeka nazonso ndizofunikira kwambiri.
Relay yowongolera ili ndi magawo awiri akulu: dongosolo lowongolera ndi dongosolo loyendetsedwa. Chifukwa chomwe ma relay owongolera amatha kuchita nawo gawo lowongolera ndikuti chizindikiro china, monga mphamvu yamagetsi, maginito, matenthedwe, kapena kuwala kwakuthupi, chimalowetsedwa mudongosolo lake ndikufikira pamtengo wina, kuchuluka kolamulidwa kwa dongosolo loyendetsedwa (lomwe limadziwikanso kuti gawo lotulutsa) limatha kusintha mwadzidzidzi kuchoka ku ziro kupita ku mtengo wina, kapena kuchokera pamtengo wina, kuwongolera ndi kupititsa patsogolo, kuwongolera, kuwongolera, kupulumutsa, kupulumutsa, kubweretsa ziro. zambiri. Makhalidwe a ma relay owongolera ndikuti amatha kuwongolera mphamvu yayikulu ndi kamphindi kakang'ono.
