Signal surge protector
Heavy-Duty RS485 / RS422 & Automation Signal Surge Arrester
Product Features
● Fast response;
● Low insertion loss, no leakage current, and stable transmission performance;
● High current flux with strong capability of discharging huge surge;
● Variety of installations to satisfy different customers' demands.
Scope of Application
Protect your critical communication lines and automated systems from unpredictable lightning strikes and industrial switching transients. Our premium RS485/RS422 Surge Protector is the ultimate safety net for serial networks, fire protection systems, and automated control loops.
Key Features & Benefits:
Comprehensive Compatibility: Tailor-made for 2-wire or 4-wire RS485/RS422 communication, fire alarm circuits, and low-voltage automation lines.
Easy, Rock-Solid Wiring: Equipped with universal screw crimping terminals, ensuring a reliable, low-resistance connection that stands up to industrial vibrations.
Advanced Equipotential Linking: Features a high-capacity surge discharge path. When dangerous voltage spikes occur, it shunts the surge directly to the earth ground within nanoseconds, limiting the output voltage to a perfectly safe level.
Don't wait for a costly system failure to upgrade your defenses. This compact surge protection device (SPD) minimizes data loss, prevents hardware damage, and ensures long-term system stability. Invest in professional-grade serial port protection today!

Quality Inspection(Test reference)
1 Inspection Reference
IEC61643.11 Surge Protective Devices (SPD) for Low-Voltage Distribution Systems
Part 1: Performance Requirements and Test Methods
GB/T 2828.1-2012 Sampling Inspection Procedures
Part 1: Sampling Plans for Inspection by Acceptance Quality Limit (AQL)
2 Incoming Inspection
Incoming material inspection is conducted based on the "Metal Parts Inspection Standard," "Plastic Parts Inspection Standard," "Electronic Parts Inspection Standard," "Auxiliary Materials Inspection Standard," and the GB/T 2828.1-2012 Sampling Inspection Procedure.
3 Finished Products Inspection
1) Routine test
Routine inspection is a 100% inspection conducted at the final stage of production on products from the production line. After inspection, no further processing is done, except for packaging and labeling.
2) Sampling test
Sampling inspection is performed according to the GB/T 2828.1 sampling standard.
3) Acceptance test
Verification inspection is a sampling inspection conducted to ensure that the product continues to meet the standard requirements. Verification inspection should be carried out according to the procedures and frequency specified by the standard.
