REC650 - Bay control
For optimized control and reliable operation of your switchyard, the REC650 is your best choice for sub-transmission applications.
REC650 offers an optimum ‘off-the-shelf’ solution for apparatus control of a single breaker in single and double busbar arrangements. The type-tested variants are equipped and configured with extensive monitoring functionality, and with default parameters for easy handling of products – from ordering, engineering, and commissioning to reliable operation.
The 650 series IEDs (Intelligent Electronic Device) have a number of useful features, such as a significantly reduced number of parameter settings and extended IED HMI functionality, including 15 dynamic three-color indication LEDs per page, on up to three pages, and configurable push-button shortcuts for different actions.
In the 650 series IEDs, the most basic parameters are set before delivery from the factory. You only need to set the parameters specific to your application. This allows you to quickly take your IEDs into operation. The application manual includes setting examples to support your protection engineers.

- Control capabilities
- Advanced interlocking
Up to ten primary apparatus can be controlled and visualized locally with REC650. The control is based on the select before operate principle, which ensures secure operation and helps avoid human error.
By selecting the control screen as a default screen in REC650, you can quickly execute control commands, and see the most important measurement values and position indications.
There are three pages of alarm indications and each page consists of 15 dynamic three-color indication LEDs. These three-color LEDs can present the status of any binary input signal on the HMI of REC650 IEDs.
The advanced interlocking functionality of REC650 allows you to avoid dangerous or damaging switchgear operations and to assure personnel safety. The IED can perform secure bay- and station wide interlocking using easy-to-use reservation functionality. Reservation prevents simultaneous operation of apparatus in the substation and ensures that the interlocking information is correct at the time of operation.
Ready-made and tested interlocking modules are available for almost any type of switchgear arrangement. The REC650 IED utilizes GOOSE messaging based on the IEC 61850 standard to perform horizontal communication and interlocking. This provides a cost-efficient solution for the interlocking.
