คำถามที่พบบ่อย
Common questions about LY26-XF waterproof and explosion-proof signal-line surge protection.
What is the LY26-XF used for?
LY26-XF is designed to protect RS485, data communication, and field-control signal lines against lightning-induced and switching transient overvoltage.
Is LY26-XF suitable for outdoor installation?
Yes. It uses a waterproof enclosed housing and is intended for outdoor signal-line applications where moisture and environmental exposure must be considered.
ควรเลือกแรงดันไฟฟ้ารุ่นใด
Select the 5V, 12V, 24V, 48V, 110V, or 220V version according to the normal operating voltage of the protected signal circuit and the corresponding maximum continuous voltage.
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.
ควรยืนยันอะไรบ้างก่อนสั่งซื้อ?
Confirm the signal voltage, maximum continuous voltage, number of protected channels, wiring arrangement, communication protocol, installation environment, grounding method, enclosure requirements, and required certification.
