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 portsTransparent for PROFIBUS configuration, i.e. no slave address requiredSupports transmission rates of 9.6 Kbps to 12 MbpsServe up to 31 Profibus clients. While using repeaters (optical - electrical), this number can extendErrors are signalized via an LED on the frontplate and a signaling contactSpecific messages that can be read at the 8-pin terminal strip serve diagnostic purposesCE, UL and CSA certifiedType Approval Certificate "Germanischer Lloyd" for use in marine area.
