6. Control
REM615 integrates functionality for the control of a 
circuit breaker via the front panel HMI or by means 
of remote controls. In addition to the circuit breaker 
control the relay features two control blocks which 
are intended for motor-operated control of discon-
nectors or circuit breaker truck and for their posi-
tion indications. Further, the relay offers one con-
trol block which is intended for motor-operated 
control of one earthing switch control and its posi-
tion indication.
Two physical binary inputs and two physical binary 
outputs are needed in the relay for each controlla-
ble primary device taken into use. Depending on the 
chosen standard configuration of the relay the 
number of unused binary inputs and binary outputs 
varies. Further, some standard configurations also 
offer optional hardware modules that increase the 
number of available binary inputs and outputs.
If the amount of available binary inputs or outputs 
of the chosen standard configuration is not suffi-
cient, the standard configuration can be modified 
to release some binary inputs or outputs which 
have originally been configured for other purposes, 
when applicable, or an external input or output 
module, for example, RIO600 can be integrated to 
the relay. The binary inputs and outputs of the ex-
-
ical binary signals of the application. The integra-
tion enables releasing of some initially reserved 
binary inputs and outputs of the relay in the stan-
dard configuration.
The suitability of the binary outputs of the relay 
which have been
selected for controlling of primary devices should 
be carefully verified, for example the make and 
carry as well as the breaking capacity. In case the 
requirements for the control-circuit of the primary 
device are not met, the use of external auxiliary re-
lays should to be considered.
The large graphical LCD of the relay's HMI includes a 
single-line diagram (SLD) with position indication 
for the relevant primary devices. Interlocking 
schemes required by the application are configured 
using the signal matrix or the application configu-
ration functionality of PCM600. 
The relay is provided with a load profile recorder. 
The load profile feature stores the historical load 
data captured at a periodical time interval (demand 
interval). The records are in COMTRADE format.
