ABB 3BDZ000398R1 RLM01 PROFIBUS Redundancy Link Module

General Information

Product ID: 3BDZ000398R1
ABB Type Designation: RLM01
Catalog Description: RLM01, PROFIBUS Redundancy Link Module for PROFIBUS line redundancy

Technical

Product Type: Interface
Protocol Type: Profibus-DP
Number of Channels: 1
Communication Speed: N/A kbit/s

Technical Information

The Redundancy Link Module (RLM01) converts a non-redundant PROFIBUS line to two redundant lines or vice versa. Field devices equipped with only a single PROFIBUS DP interface can be integrated into the redundant PROFIBUS network using the RLM01. Acting like an active switch, it converts two redundant lines to one PROFIBUS DP line or vice versa. The RLM01 amplifies signal form and amplitude of the incoming data and monitors activities and error statuses of all three lines.
