confi gurations
e REM615 relay main application is protection,
control, metering and monitoring of asynchronous
motors and o ers two standard con gurations whose
relay functions and features are based on the analog
inputs ordered for each con guration. See Tables 1
and 2 for details.

Description Std. con g. - functional application
Current-based metering and protection
A
Current-based and voltage-based metering and protection
C
One con guration comprises only current analog inputs
useful in cost-e ective motor protection, control and
monitoring industrial and utility applications. e second
con guration includes the addition of voltage analog inputs
for more comprehensive motor protection and control
applications. Both con gurations include standard features
of metering, monitoring and control plus sequence of event,
fault and digital waveform recording. Advanced Ethernet
communications is included standard with parallel support of
DNP3.0 Level 2+*, Modbus and IEC61850 and SNTP over
TCP/IP. Optional RS-232 and RS-485 serial communication
ports are available that support user programmable DNP3.0
Level 2+* or Modbus protocols. Included with the optional
serial communication ports is IRIG-B time synchronization.
* The DNP3.0 Level 2+ implementation includes some Level 3 functionality.
