About ABB REC650 BAY CONTROL RELAY

ABB REC650 BAY CONTROL RELAY

REC650 is used for the control, protection and monitoring of different types of bays in power networks. The IED is especially suitable for applications in control systems with distributed control IEDs in all bays with high demands on reliability.

Flexible Communication and Integration

The ABB REC650 relay supports modern substation automation and interoperability through IEC 61850, IEC 60870-5-103, and Modbus protocols. This flexibility makes it easy to integrate into new or existing systems, ensuring efficient and reliable control over multiple bays within a substation environment. Its clock synchronization capabilities with SNTP and IRIG-B channels further enhance system coordination.


Comprehensive Protection and Control

Offering a wide range of protection features, including overcurrent, breaker failure, earth fault, and circuit supervision, the REC650 provides robust bay supervision. The relay records up to 500 events and includes a disturbance recorder for accurate fault analysis, improving response times and operational safety. Optional analog inputs allow for expanded monitoring capability.


Versatile Installation and Operation

Designed for flush, panel, or 19-inch rack mounting, the REC650 is adaptable to various substation requirements. The device accommodates universal power supplies and features screw-type terminals in a rear terminal block for secure connections. The graphical LCD with LED indicators streamlines local monitoring and configuration, while firmware upgrades are possible via front or rear ports.
