Description

LS-CH Series 2-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 full-mode fine protection for two signal lines.

Featuring a plug-in module design, the product allows for easy replacement without interrupting signal transmission. 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 Features
● It can simultaneously protect four communication signal lines.
● Multi level protection, high flow rate, and low residual pressure.
● The module can be hot swapped and replaced without interrupting signal transmission.
● Suitable for installation in LPZ 2-3 and subsequent lightning protection zones, it is a lightning arrester for communicationequipment such as communication dedicated lines, telemetry signals, measurement and control signals, PLC analogcontrol systems, and 4-20mA current loops.

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 plug-in module design allows for easy replacement, but disconnect the signal line if possible during replacement.

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.

FAQ

Q1: What is the difference between full-mode protection and line-line mode protection?

A1: Full-mode protection covers line-line and line-ground paths, while line-line mode only protects line-line paths. This product offers full-mode fine protection.

Q2: Can it be used for both DC and AC signal lines?

A2: It is specifically designed for DC signal lines (5Vdc/12Vdc/24Vdc/48Vdc). For AC signals, choose dedicated AC signal SPD models.

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 service life of the product?

A5: Under normal operating conditions, the service life is 5-8 years. It may vary based on surge frequency and environmental factors.
