ABB RLM02 Redundancy Link Module for Profibus DP/FMS

Redundancy Link Module RLM02 – Enhancing PROFIBUS Network Reliability

The Redundancy Link Module RLM02 is a critical component designed to increase network reliability and flexibility in PROFIBUS DP systems. By seamlessly converting a non-redundant PROFIBUS line into two redundant RS485 lines (or vice versa), the RLM02 ensures continuous operation, even in the event of a communication failure, making it ideal for mission-critical industrial applications.

This module can be strategically positioned at various points within the network, such as directly after a master, before a bus segment with multiple slaves, or in front of an individual slave. With its easy integration and advanced redundant configuration, the RLM02 helps maintain uninterrupted data flow in automation systems, making it a valuable asset for industries relying on high-availability systems.
