Product Description
LS-W2L Series Ultra-Thin 2-Wire Control Signal Lightning Arrester (Line-Line Mode) 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 line-line mode fine protection for two signal lines.
Featuring an ultra-thin design (7mm thickness), the product saves space in control cabinets, making it ideal for space-constrained environments. The module comes with guide rail ground contact, enhancing grounding reliability. The multi-level protection circuit ensures high flow rate and low residual voltage, specifically optimizing line-line surge protection.

Notices
1.The ultra-thin design (7mm) saves space, but avoid installing in areas with strong mechanical impact.
2.Select the model based on the signal line's nominal operating voltage (5Vdc/12Vdc/24Vdc/48Vdc).
3.The module comes with guide rail ground contact; ensure the DIN Rail is properly grounded.
4.Use wiring with cross-sectional area 0.5mm²-2.5mm² and tighten screws to 1N·m torque.
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.
FAQ
Q1: What is the thickness of the product?
A1: The product thickness is only 7mm, featuring an ultra-thin design to save space in control cabinets.
Q2: What is the function of the guide rail ground contact?
A2: It enhances grounding reliability by utilizing the DIN Rail as a ground path, simplifying installation.
Q3: What is the difference between line-line mode and line-ground mode?
A3: Line-line mode protects against surges between two signal lines, while line-ground mode protects against surges between signal lines and ground. This product optimizes line-line protection.
Q4: Does the product require external power supply?
A4: No, it is passive and does not require external power supply, drawing minimal power from the signal line.
Q5: Can it be used for differential signal lines?
A5: Yes, line-line mode protection is ideal for differential signal lines, providing targeted surge shielding.
