Voltalis echelon pcbA voltalis relays li etselitsoe ho laola hona joale ka potoloho.Hangata li sebelisetsoa ho bulela le ho tima lisebelisoa tsa motlakase, tse kang mabone, li-motor, joalo-joalo. Li-relay li hokahane le boto ea potoloho e hatisitsoeng (PCB) 'me li sebelisetsoa ho laola phallo ea hona joale.PCB e na le likarolo tse 'maloa, tse kang resistors, capacitor, transistors, diode, le likarolo tse ling tsa elektroniki.The voltalis relay e hokahane le PCB ka sete ea lithakhisa tse hokahaneng le likarolo tse fapaneng tsa relay ea potoloho e ntan'o sebelisoa ho laola phallo ea hajoale ka ho chencha lithakhisa tse bulehileng kapa tse koetsoeng.
