ABB RLM01 Redundancy Link Module

Sku: E13385-2

ABB No. RLM01 

Field devices equipped with only one PROFIBUS DP interface can be integrated into a redundant PROFIBUS network by using the redundant link module RLM01. It is like an active switch, converting two redundant lines into a PROFIBUS DP line and vice versa. RLM01 amplifies the signal form and amplitude of the input data, and monitors the activity and error status of all three lines.

• 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.
