Os estágios de desacoplamento óptico evitam que loops de terra e ruídos elétricos de alta frequência corrompam as saídas de tensão do sinal de chama. O amplificador de estado sólido condiciona os sinais CA de nível microampere gerados pelos sensores UV C7027\/C7035\/C7044 em um sinal analógico normalizado de 0,0 a 5,0 VCC, legível nos pontos de teste do painel frontal e nos barramentos de diagnóstico do sistema.\u003c\/p\u003e\n\u003ch3\u003ePerguntas frequentes\u003c\/h3\u003e\n\u003cp\u003eP: Qual é o tempo de resposta à falha de chama (FFRT) configurado no amplificador R7849A1023?\u003c\/p\u003e\n\u003cp\u003eR: O R7849A1023 fornece um tempo de resposta à falha de chama padrão de 2,0 a 4,0 segundos após a perda da radiação ultravioleta detectada.\u003c\/p\u003e\n\u003cp\u003eP: Quais sensores de chama Honeywell são compatíveis com este amplificador?\u003c\/p\u003e\n\u003cp\u003eR: O módulo faz interface direta com os detectores de chama ultravioleta miniatura Honeywell C7027, C7035 e C7044.\u003c\/p\u003e\n\u003ch3\u003eDiretrizes de instalação em campo\u003c\/h3\u003e\n\u003col class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eCertifique-se de que a alimentação elétrica principal da base do módulo de relé da Série 7800 esteja desenergizada antes de inserir ou remover o módulo amplificador.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAlinhe os pinos do conector de borda na parte traseira do R7849A1023 com o slot designado para o amplificador no módulo de relé da Série 7800.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePressione firmemente o módulo até que as linguetas laterais de retenção se encaixem na posição.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMeça a tensão CC da chama entre os bornes de teste positivo (+) e negativo (-) do painel frontal usando um voltímetro de alta impedância (é necessário um mínimo de 0,8 VCC para a operação estável do queimador).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":67667048300853,"sku":"R7849A1023","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/R7849A1023.png?v=1791603776","url":"https:\/\/www.5gplc.com\/pt\/products\/honeywell-r7849a1023-burner-control-ultraviolet-flame-amplifier-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
