Data & Signal Surge Protectors
Data and signal surge protectors are critical for protecting low-voltage communication and control lines from damaging voltage transients. These surges can be caused by lightning strikes, power fluctuations, switching events, or electromagnetic interference and can disrupt or permanently damage sensitive electronic equipment. Surge protection devices are designed to absorb excess energy and divert it safely to ground, preserving the integrity of connected systems.
These protectors are commonly used to safeguard Ethernet networks, RS-232 and RS-485 communication lines, 4–20 mA current loops, and other control and instrumentation circuits. Equipment such as routers, switches, programmable logic controllers (PLCs), remote sensors, and automation devices rely on signal surge protection to maintain reliable operation in industrial, commercial, and IT environments where uninterrupted communication is essential.
Many data and signal surge protectors feature pluggable designs for ease of installation and maintenance. These devices can be DIN rail mounted or integrated into control panels and structured wiring enclosures. Internally, they use technologies such as gas discharge tubes and transient voltage suppression (TVS) diodes to allow normal signal transmission while rapidly diverting harmful overvoltage events away from sensitive circuitry.
