FAQ
Common questions about LY10 DIN-rail pluggable data signal surge protector selection and installation.
What is the LY10 signal surge protector used for?
LY10 is installed in series with low-voltage data or control lines to help suppress induced transient overvoltage before it reaches sensitive communication and automation equipment.
Is LY10 suitable for RS485 communication lines?
Oui. Il est conçu pour RS485 et des lignes de données industrielles similaires utilisées par les PLC, les compteurs, les capteurs, les contrôleurs d'automatisation et les équipements de surveillance à distance.
Which operating voltage should be selected?
Select the 12V, 24V, or 48V version according to the normal operating voltage of the protected signal circuit. The selected maximum continuous voltage must remain above the circuit’s normal operating voltage.
Will the LY10 affect data transmission?
The listed transmission rate is up to 10Mbps and the listed insertion loss is no more than 0.2dB. Compatibility should still be confirmed against the actual communication protocol, impedance, and cable length.
How is the LY10 installed?
It is mounted on a DIN rail and connected in series ahead of the protected equipment. The protected and unprotected sides must follow the wiring diagram, and the grounding conductor should be kept as short as practical.
Que doit-on confirmer avant de commander ?
Confirm the signal voltage, maximum continuous voltage, line current, communication protocol, transmission rate, number of conductors, terminal arrangement, grounding method, and required surge withstand level.
