Na adequa\u00e7\u00e3o de uma m\u00e1quina \u00e0 norma NR12<\/a>, existem alguns fatores que determinam a fun\u00e7\u00e3o e o modelo do rel\u00e9 de seguran\u00e7a a ser usado.<\/h1>\n

Tr\u00eas subsistemas envolvem o rel\u00e9 de seguran\u00e7a e estes est\u00e3o diretamente ligados \u00e0 especifica\u00e7\u00e3o do modelo mais adequado para a aplica\u00e7\u00e3o: o sensor na entrada, as caracter\u00edsticas do rel\u00e9 e os canais de sa\u00edda para o controle dos contatores de pot\u00eancia.<\/p>\n

<\/p>\n

\"subsistemas\"Inicialmente \u00e9 necess\u00e1rio saber o tipo do sensor<\/strong> que o rel\u00e9 ir\u00e1 monitorar, pois os modelos podem variar se a aplica\u00e7\u00e3o for para bot\u00e3o de emerg\u00eancia, porta de seguran\u00e7a, cortina de luz, acionamento bimanual ou outros. Al\u00e9m disso, existem modelos de rel\u00e9s exclusivos para cada sensor ou ainda aqueles que s\u00e3o multifuncionais.<\/p>\n

Toda vez que o rel\u00e9 for atuado, fun\u00e7\u00f5es operacionais e de movimenta\u00e7\u00e3o s\u00e3o imediatamente interrompidas, sejam elas parciais ou totais em uma m\u00e1quina. Para que o processo seja retomado, al\u00e9m de todo o sistema estar em modo seguro, \u00e9 necess\u00e1rio um comando para reativar os canais de sa\u00edda. Esse comando de reset<\/strong> pode ser manual ou autom\u00e1tico dependendo do processo e riscos que envolvem o operador desta m\u00e1quina.<\/p>\n

O controle dos contatores em s\u00e9rie, respons\u00e1veis pelo seccionamento redundante da alimenta\u00e7\u00e3o da m\u00e1quina, \u00e9 realizado pelos canais de sa\u00edda do rel\u00e9 de seguran\u00e7a. Dependendo de onde ser\u00e3o instalados estes contatores e a corrente necess\u00e1ria para seu acionamento, este controle pode ser realizado atrav\u00e9s de um ou mais canais de sa\u00edda.<\/p>\n

Normalmente os rel\u00e9s de seguran\u00e7a possuem 2 ou mais canais de sa\u00edda<\/strong> e por isso o mais usual sempre foi conectar um dispositivo por canal de sa\u00edda. Por\u00e9m se os contatores estiverem instalados no mesmo painel que o rel\u00e9 e o mesmo suportar a corrente necess\u00e1ria para atracar os dois contatores simultaneamente, estes podem ser controlados por apenas um \u00fanico canal.<\/p>\n
