Description
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 RLM01amplifies signal form and amplitude of the incoming data and monitors activities and error statuses of all three lines.

RLM01 at a glance:
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. Conversion of one simple, non redundant PROFIBUS line into two reciprocally redundant lines A/B and vice versa.
