Product Overview

The ABB REM611 is a specialized numerical protection relay designed to safeguard asynchronous motors in manufacturing and process industries. As part of the ABB Relion® 611 series, this device delivers comprehensive protection, control, and measurement capabilities for medium and small-sized motors driving equipment such as pumps, conveyors, crushers, and fans.

Engineered for reliability, the REM611 features a pre-configured standard setup that significantly reduces engineering and commissioning time. Its compact, pluggable design allows for rapid installation and testing, making it an ideal solution for both new installations and retrofit projects where space and downtime are critical factors.

Key Features & Benefits

  • Pre-configured Protection: The relay ships with factory-tested, application-specific settings, minimizing setup errors and accelerating deployment.

  • Self-Healing Communication: Supports High Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) via an optional second Ethernet bus, ensuring uninterrupted communication in critical networks.

  • Advanced Connectivity: Fully supports IEC 61850 (Edition 1 and 2), including GOOSE messaging, allowing seamless integration into substation automation systems.

  • User-Friendly Interface: Equipped with a web browser-based Human Machine Interface (HMI) featuring an I/O matrix and visual selection for intuitive operation and monitoring.

  • Pluggable Design: The withdrawable plug-in unit design facilitates easy replacement and maintenance without disturbing wiring, maximizing system availability.
