The REC670 (1MRK004814-AC) is a bay-level control and monitoring unit from ABB’s Relion® product family, engineered for high-voltage transmission and distribution substations. It consolidates control, supervision, and communication functions into a single IED (Intelligent Electronic Device), reducing panel complexity while supporting full digital substation architectures.
Designed and manufactured in Switzerland, the REC670 complies with IEC 61850 Edition 2, enabling GOOSE messaging, sampled values (SV), and MMS services over Ethernet. It interfaces directly with circuit breakers, disconnectors, and auxiliary systems, providing interlocking, sequence-of-events recording, and remote SCADA integration.

FAQ
Q: Is the REC670 a protection relay?
A: No—it focuses on control and monitoring. For protection functions, ABB offers the REL670. The REC670 often works alongside it in the same bay.
Q: Can it replace older RTUs?
A: Yes—its IEC 61850 support and flexible I/O make it suitable for modernizing legacy substations without rewiring entire panels.
Q: Does it support cybersecurity features?
A: Yes—supports IEEE 802.1X, VLAN tagging, and role-based access control when configured with ABB’s PCM600 engineering tool.
