Voltalis echelon pcbA voltalis relays dzakagadzirirwa kudzora ikozvino mudunhu.Iwo anowanzo shandiswa pakuchinja nekudzima midziyo yemagetsi, semwenje, mota, nezvimwewo. Marelay akabatana neakadhindwa redunhu board (PCB) uye anoshandiswa kudzora kuyerera kwezvino.Iyo PCB ine zvikamu zvakati wandei, senge resistors, capacitors, transistors, diode, uye zvimwe zvemagetsi zvikamu.Iyo voltalis relay yakabatana nePCB kuburikidza neseti yepini iyo yakabatana kune akasiyana zvikamu zvedunhu relay inozoshandiswa kudzora kuyerera kwazvino nekuchinja mapini akavhurika kana kuvharwa.
