ABB REM620E_1G Control Relay

Product Overview

The ABB REM620E_1G is a high-performance motor protection and control relay. It is designed for medium and large asynchronous and synchronous motors. The relay provides comprehensive protection during start-up, normal operation, and fault clearance. It features advanced supervision via RTD and mA measurements. 

Technical Specifications

• Model: REM620E_1G (Relion® 620 Series).

• Motor Support: Asynchronous and Synchronous types.

• Protection Functions: Start-up monitoring, thermal overload, and fault clearance.

• Supervision: RTD (Temperature) and mA (Process) inputs.

• Communication: Native IEC 61850 (Editions 1 & 2).

• Redundancy: Supports HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol).

• Digital Integration: GOOSE messaging and IEC 61850-9-2 LE (Sampled Values).

• Display: Large graphical HMI with customizable SLD.

• Interface: Local HMI and web-browser-based access.

Key Features and Engineering Advantages

• Advanced Digital Communication: Native support for GOOSE messaging allows for high-speed peer-to-peer communication between relays, reducing hardwired logic.

• Network Redundancy: Equipped with HSR and PRP protocols. This ensures zero-packet-loss communication even if a network path fails.

• Reduced Wiring Costs: Support for IEC 61850-9-2 LE allows the relay to receive digitized sensor values from merging units, significantly decreasing copper wiring requirements.

• Cyber-Secure Access: The web-browser-based HMI provides secure, remote access for diagnostics and event log analysis without specialized software.

• Withdrawable Design: The "plug-in" architecture permits the internal relay components to be removed for maintenance while the outer case stays wired in the panel.
