LS-CH Series 4-Wire Control Signal Lightning Arrester is designed for communication equipment such as dedicated communication lines, telemetry signals, measurement and control signals, PLC analog control systems, and 4-20mA current loops. Suitable for installation in LPZ 2-3 and subsequent lightning protection zones, it provides comprehensive protection for four communication signal lines simultaneously.

Featuring a hot-swappable module design, the product allows for module replacement without interrupting signal transmission, reducing maintenance downtime. The multi-level protection circuit ensures high flow rate and low residual voltage, effectively shielding signal lines from lightning-induced surges and electrostatic discharge. With a line-to-line bandwidth of 3MHz, it supports high-speed signal transmission without distortion.

Product Specification

Notices

1.Select the model based on the signal line's nominal operating voltage (5Vdc/12Vdc/24Vdc/48Vdc).

2.Use wiring with cross-sectional area 0.5mm²-2.5mm² and tighten screws to 1N·m torque.

3.The hot-swappable function allows module replacement during operation, but ensure proper alignment to avoid signal interruption.

4.Ensure reliable grounding with ground resistance ≤4Ω to guarantee surge diversion.

5.Avoid installing in environments with strong electromagnetic interference to prevent signal distortion.

6.Regularly inspect the module for loose connections or physical damage; replace if faulty.
