ABB RLM01 3BDZ000398R1 PROFIBUS Redundancy Link Module

Field devices equipped with only a single PROFIBUS DP interface, can be integrated in the redundant PROFIBUS network by using the Redundancy Link Module 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.

Benefits:
-Three PROFIBUS ports
-Transparent for PROFIBUS configuration, i.e. no slave address required
-Supports transmission rates of 9.6 Kbps to 12 Mbps
-Serve up to 31 Profibus clients. While using repeaters (optical - electrical), this number can extend
-Errors are signalized via an LED on the frontplate and a signaling contact
-Specific messages that can be read at the 8-pin terminal strip serve diagnostic purposes
-CE, UL and CSA certified
-Type Approval Certificate "Germanischer Lloyd" for use in marine area.
