FAQ
Common questions about LY26-XF waterproof and explosion-proof signal-line surge protection.
Para que é utilizado o LY26-XF?
O LY26-XF é projetado para proteger linhas de comunicação de dados RS485 e linhas de sinal de controle de campo contra sobretensões induzidas por relâmpagos e transientes de comutação.
O LY26-XF é adequado para instalação externa?
Sim. Ele utiliza uma caixa selada à prova d'água e é destinado a aplicações de linha de sinal ao ar livre, onde a umidade e a exposição ambiental devem ser consideradas.
Qual versão de voltagem deve ser selecionada?
Selecione a versão de 5V, 12V, 24V, 48V, 110V ou 220V de acordo com a tensão de operação normal do circuito de sinal protegido e a correspondente tensão máxima contínua.
Does LY26-XF support single-channel and dual-channel protection?
Yes. The product is available with single-channel protection for terminals 1 and 2, or dual-channel protection for terminals 1, 2, 3, and 4.
Will the protector significantly affect the signal?
The listed insertion loss is no more than 0.3dB. Final compatibility should still be checked against the actual protocol, line impedance, transmission distance, and signal frequency.
O que deve ser confirmado antes de fazer o pedido?
Confirm the signal voltage, maximum continuous voltage, number of protected channels, wiring arrangement, communication protocol, installation environment, grounding method, enclosure requirements, and required certification.
