Surge Protector AXON-RS485 Symmetric Line

The Surge Protector AXON-RS485 is a high-performance data line surge protective device designed to safeguard RS-485 communication systems from transient overvoltages. It provides symmetric line protection (differential and common mode) for one differential pair plus ground, ensuring reliable operation in industrial environments.

Advantages

Protects sensitive RS-485 equipment from lightning-induced surges and switching transients. Features ultra-fast response time (<1 ns) and low voltage protection levels. Compact DIN rail mount design simplifies installation in control cabinets.
