Description
🔹 Product Description
The ABB REG670 is an electronic protection module associated with ABB Relion 670 series generator protection systems. REG670 is designed for generator protection, control, measurement, and monitoring applications in power-generation installations. Its protection functions can include generator differential protection, backup overcurrent protection, voltage-related protection, abnormal operating-condition protection, and stator/rotor earth-fault protection depending on the configured version. ABB documentation also identifies REG670 as part of the Relion protection and control family and supports integration with IEC 61850-based protection and automation architectures.
This module is suitable for maintenance, replacement, refurbishment, and system-integration work involving existing ABB REG670 installations. Because REG670 systems were supplied in different hardware and functional configurations, the complete ordering code, hardware revision, configuration, connectors, and firmware should be checked before replacement.

🔹 Application
REG670 is intended for generator protection applications where electrical measurements and protection functions are processed by an intelligent electronic device. ABB documentation describes applications including generator differential protection, backup protection, generator abnormal operating-condition protection, and stator earth-fault protection.
The exact capabilities depend on the REG670 configuration. Some configurations provide 12 analog inputs, while other hardware configurations and options can provide additional I/O and protection functions.
🔹 Replacement Notes
Before installing this module as a replacement, compare the REG670 model/configuration, hardware revision, terminal arrangement, firmware version, communication interfaces, and protection configuration with the existing unit. REG670 variants are not necessarily interchangeable simply because they share the REG670 designation.
