ABB RLM01 3BDZ000398R1 PROFIBUS Redundancy Link Module

Description

The ABB RLM01 3BDZ000398R1 PROFIBUS Redundancy Link Module is a member of the ABB RLM series, designed to enable reliable PROFIBUS network redundancy for industrial automation systems. Key features include automatic fault switching, plug-and-play functionality, and multiple safety features, with construction using high-quality materials and advanced manufacturing processes to ensure durability. It supports critical functions such as signal conversion, control implementation, and system safety protection, and can convert between single-bus and redundant dual-bus PROFIBUS DP configurations, making it suitable for deployment after PROFIBUS DP masters or at slave stations.

Technical specifications include a 24V DC input voltage (with a stable operating range of +20 to +33V DC) and a power consumption of approximately 3.6W. The module is equipped with 3 PROFIBUS ports (A, B, C) to support redundant links, with communication speeds ranging from 9.6 Kbps to 12 Mbps, covering 10 common PROFIBUS transmission rates with options for dip-switch setting or auto-rate adaptation. It can support up to 31 PROFIBUS clients, with expandability via optical repeaters, and works with cables of 0.14 to 1.5 square millimeters cross-sectional area. Operating temperature ranges from 0 degrees Celsius to 50 degrees Celsius, with storage/transport temperatures from -30 degrees Celsius to 85 degrees Celsius, and a maximum operating relative humidity of 75% without condensation. Additional industrial-grade features include IP30 protection, a reinforced wave-pattern aluminum housing, 35mm DIN rail mounting, optical coupling isolation to reduce interference, relay alarm output, and dual power redundancy with isolation protection. It is ideal for use in industrial control systems, process control systems, discrete manufacturing systems, building automation, and power transmission and distribution systems.
