Voltalis echelon pcbA voltalis relays ziyilelwe ukulawula langoku kwisekethe.Ngokuqhelekileyo zisetyenziselwa ukulayita nokucima izixhobo zombane, ezifana nezibane, iinjini, njl.njl. Iireyiyidi ziqhagamshelwe kwibhodi yesekethe eprintiweyo (PCB) kwaye zisetyenziselwa ukulawula ukuhamba kwangoku.I-PCB inamacandelo amaninzi, anje nge resistors, capacitors, transistors, diodes, kunye namanye amalungu e-electronic.I-voltalis relay iqhagamshelwe kwi-PCB ngeseti yezikhonkwane ezidityaniswe kumacandelo ahlukeneyo e-relay yesekethe emva koko isetyenziselwa ukulawula ukuhamba kwangoku ngokutshintsha izikhonkwane ezivulekileyo okanye ezivaliweyo.
