Overview
The ABB RER 103 is a robust bus communication module designed for medium-voltage protection and control systems. It enables data exchange between Intelligent Electronic Devices (IEDs) and higher-level automation systems through fiber-optic communication, ensuring high immunity to electromagnetic interference and excellent electrical isolation.
Designed for seamless integration with ABB’s REF, REM, and RET protection relay families, the RER 103 supports both star and ring topologies, providing flexibility for various substation network architectures. Its compact footprint and convenient DIN-rail mounting simplify installation within switchgear panels. In addition, hot-swapping and automatic node addressing reduce commissioning time and support easy maintenance.
For instance, in a substation equipped with REF 543 feeder terminals, the RER 103 ensures fast and secure communication between relays and the station automation system for real-time fault coordination.
