Description
🔹 Product Overview
The ABB REC670 1MRK004814-AC is a Relion 670 series Bay Control Unit designed for control, monitoring, interlocking, and automation functions in medium- and high-voltage substations. The REC670 integrates bay-level control functions for circuit breakers, disconnectors, and related switchgear while providing communication with station-level automation systems. Available documentation identifies the REC670 as a pre-configured bay-control IED within the Relion 670 family.
The unit supports configurable binary inputs and outputs and can be integrated into substation communication architectures using protocols such as IEC 61850 and IEC 60870-5-103. The exact I/O configuration and communication options depend on the ordered hardware configuration.
