Product Overview
RLM01 with order number 3BDZ000398R1 is an ABB PROFIBUS redundancy link module for Advant OCS / 800xA control systems. It is used to maintain communications availability in PROFIBUS RS-485 networks by supervising multiple bus paths and switching the active channel when a fault condition is detected. The module also performs signal regeneration, helping preserve waveform integrity and communication margin on extended or electrically noisy segments.
Designed for continuous service in industrial cabinets, this redundancy link module supports diagnostic visibility via front indicators and alarm signaling, enabling faster troubleshooting in critical control networks.
