ABB 1MRS120511.010 RJ-45 Connection Data Cable

ABB 1MRS120511.010 REA 101 Connection Data Cable is a 10-meter RJ-45 data link designed to interconnect ABB REA 101 devices with compatible REA modules such as REA 103/5/7. The part number 1MRS120511.010 identifies the 10 m length, with RJ-45 connectors on both ends, a member of ABB’s family of 1MRS120511 cables that includes a 1 m variant (1MRS120511.001) used in the same REA interface ecosystem. This cable is referenced in ABB documentation and partner listings as the REA 101 connection cable, confirming its role in data communication within ABB automation configurations. It supports direct, point-to-point data exchange between REA devices when assembling or expanding ABB REA-based control architectures, particularly in setups where REA 101 must communicate with REA 103/5/7 units over a long distance. As a dedicated ABB accessory, it carries the REA 101 designation and aligns with the REA interface family, providing a targeted solution for engineers integrating REA components in factory automation or process control systems.
