Abstract

COMUTAçãO POR RELé. A presente invenção refere-se a uma comutação por relé com pelo menos dois relés (K1, K2) situados em conexão em série ou em conexão paralela em uma tensão de alimentação (UV). Para obter uma sequência de desconexão de relé em caso de interrupção da tensão de alimentação e portanto para aumentar a segurança, é previsto que os relés (K1, K2) apresentem tensões mínimas de manutenção (UHalt,minl; UHalt,min2) e/ou resistências de bobina (Rspl; Rsp2)
