Bay control REC670/650
Relion® 670 and 650 series

For optimized control and reliable
operation of your switchyard
The REC670 and REC650 Bay control IEDs (Intelligent
Electronic Device) are designed for the control, monitoring
and protection of circuit breakers, disconnectors, and
earthing switches in different switchgear configurations.
Providingextensive application opportunities, both these
IEDs are designed for IEC 61850. They implement the
core values of this standard, which ensures open, futureproof and flexible system architectures, with state-of
the-art performance. The IEDs are therefore ideal for
refurbishment and extension of existing installations as
well as for new installations.

REC670 – maximum flexibility and performanceThe REC670 IEDs provide customized or pre-configured
control solutions for any type of switchgear and for different
switchgear configurations. The customized REC670 gives you
the freedom to select the functionality entirely according to
your needs. The REC670 variants simplify handling since the
basic functionality is included and pre-configured. If needed,
you can add optional functionsto easily increase the functionality of the REC670 IEDs to meet the specific requirements of
your switchyard.
REC670 enables the manual control of a tap-changer from a
Substation Automation system. It can also integrate advanced
voltage control for transformers in a substation in a single IED.
This eliminates the need for dedicated voltage control devices
in cases where the transformerprotection is not equipped
with voltage control.

REC650 – ease of use from ready-to-use solutions
R EC650 offers optimum ‘off-the-shelf’ solutions for control
applications in single breaker applications in single and
double busbar arrangements. For double busbar arrangements, control of a bus coupler bay is also available.
The type-tested variants are equipped and configured with
completefunctionality, and with default parameters for
easy handling of products – from ordering, engineering
and commissioning to reliable operation.
The 650 series IEDs introduce a number of innovations, such as
significantly reduced parameter settings and extended IED HMI
functionality including 15 dynamic three-color-indication LEDs
per page, on up to three pages, and configurable push-buttonshortcuts for different actions. In the 650 series IEDs, all basic
parameters are set before delivery from the factory. You only
need to set the parameters specific to your application, such as
line data. This allows the IEDs to be quickly taken into operation.
Outstanding control capabilities
The bay control IEDs feature a large HMI for local control and
instant access to important data,such as settings, events
and disturbance information. It also provides a quick overview
of the status of the bay with position indications and service
values. You can freely select which of the measurements
available in the IEDs should be shown on the HMI of the IEDs.
You can control and visualize locally up to thirty primary
apparatus in up to six bays with REC670, and up to eight
primaryapparatus in one bay 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 values. REC650 features three pages of alarm indications
and each page consists of 15 dynamic three-colorindication
LEDs. These three-color LEDs can present the status of any
binary input signal on the HMI of REC650 IEDs.
The Protection and control IED manager PCM600 tool offers a
symbol library according to IEC and ANSI standards. You can
use this tool to easily configure the graphical display of the

IEDs to correspond with your needs and to your substation.
