Product information

Description

Surge Protector RoGer AX-12 for RS485 Bus is a compact protective module designed to be installed on RS485 communication lines. It safeguards differential data pairs against transient overvoltages caused by lightning strikes, switching events or ground potential differences. The device is intended to improve the longevity and reliability of serial RS485 networks used in industrial control, building automation and other systems that rely on robust differential communication.

Advantages

The unit provides dedicated protection for RS485 differential pairs without affecting signal integrity, enabling continued data transmission during minor disturbances. Its design supports straightforward installation on communication lines and reduces the risk of equipment damage and downtime caused by transient overvoltages. The protector is compact and suitable for inline or terminal placement on existing wiring systems.

Suitable for

Industrial control systems using RS485 networks
Building automation and HVAC communication buses
Access control and security system serial links
Remote telemetry and monitoring installations over RS485
Long-distance RS485 runs exposed to electrical disturbances

Key specifications

Protection type: transient overvoltage suppression for differential RS485 pairs
Application: inline protection for serial communication buses
Form factor: compact module suitable for wiring terminations
Connection: compatible with two-wire differential RS485 data pair
Operational environment: designed for installation in industrial and building automation cabinets or on distribution lines

How to use

Install the surge protector in series with the RS485 data pair at the entry point of the protected segment or adjacent to equipment to be protected. Ensure correct wiring of the differential pair through the protector and verify secure mechanical and electrical connections. After installation, power and signal continuity checks should be performed to confirm normal RS485 communication. Replace the device if visible damage occurs after a surge event or if communication anomalies persist following an overvoltage incident.

Usage recommendations

Place protectors at both ends of long RS485 runs and near critical devices to minimize exposure to transient overvoltages. Maintain good grounding and equipotential bonding practices in the installation environment to enhance overall surge protection effectiveness.
