REM615 ANSI 5.0 FP1
Motor protection & control
1. Description
REM615 is a dedicated motor protection and con-
trol relay designed for the protection, control, mea-
surement and supervision of asynchronous motors
in manufacturing and process industry. REM615 is a
member of ABB’s Relion® product family and part
of its 615 protection and control product series.
The 615 series relays are characterized by their
compactness and withdrawable-unit design.
Re-engineered from the ground up, the 615 series
has been designed to unleash the full potential of
the IEC 61850 standard for communication and in-
teroperability between substation automation de-
vices. Once the standard configuration relay has
been given the application-specific settings, it can
directly be put into service.
The 615 series relays support a range of communi-
cation protocols including IEC 61850 with Edition 2
support, process bus according to IEC 61850-9-2
LE, Modbus® and DNP3.
2. Standard configuration
REM615 is available in four alternative standard
configurations. The standard signal configuration
can be altered by means of the graphical signal ma-
trix or the graphical application functionality of the
Protection and Control IED Manager PCM600. Fur-
ther, the application configuration functionality of
the relay supports the creation of multi-layer logic
functions using various logical elements including
timers and flip-flops. By combining protection
functions with logic function blocks, the relay con-
figuration can be adapted to user-specific applica-
tion requirements.
The relay is delivered from the factory with default
connections described in the functional diagrams
for binary inputs, binary outputs, function-to-func-
tion connections and alarm LEDs. Some of the sup-
ported functions in REM615 must be added with
the Application Configuration tool to be available in
the Signal Matrix tool and in the relay. The positive
measuring direction of directional protection func-
tions is towards the outgoing feeder.
