LS-CSE Series 2-Wire Control Signal Lightning Arrester (Line-Ground 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-ground mode fine protection for two signal lines.

Featuring an integrated module structure, the product supports 35mm DIN Rail mounting with through flow. The multi-level protection circuit ensures high flow rate and low residual voltage, specifically optimizing line-ground surge protection. With a line-to-line bandwidth of 3MHz, it supports high-speed signal transmission without distortion.

Notices

1.This product adopts line-ground mode protection, suitable for scenarios where line-ground surges are the main threat.

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

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

4.Ensure reliable grounding with ground resistance ≤4Ω to guarantee surge diversion (critical for line-ground protection).

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 difference between line-line mode and line-ground mode?

A1: 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-ground protection.

Q2: Why is grounding critical for this product?

A2: Line-ground mode protection relies on effective grounding to divert surge energy; poor grounding will significantly reduce protection performance.

Q3: What is the load current capacity of the product?

A3: The maximum load current is 500mA, suitable for most industrial control signal lines.

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: What is the voltage protection level for line-line surges?

A5: The line-line voltage protection level is ≤30V / ≤60V / ≤120V / ≤190V (depending on model), providing basic line-line surge protection while focusing on line-ground protection.
