ABB RLM01 3BDZ000398R1 PROFIBUS Redundancy Link Module
Description
ABB RLM01 3BDZ000398R1 PROFIBUS Redundancy Link Module is a high-performance industrial communication module designed for ABB distributed control systems (DCS) and PROFIBUS DP/FMS networks. It acts as an intelligent switch to convert a single PROFIBUS DP line to two redundant lines (or vice versa), ensuring uninterrupted data transmission by automatically switching to a backup line if the primary link fails.
