For LVS Digital feeder applications FC610 is typi-
cally used to indicate the status and the com-
mon fault of the main switching device in addi-
tion to the measurement values.
To ensure a correct indication of the status in
the single line representations of e.g. CMES con-
dition monitoring system it is mandatory to
connect these signals to the FC610 DI0/DI1 as
described before!
When the digital inputs are powered by external supply, OUT/M terminal must be connected
as follows.

1) The common terminal of digital inputs is internally connected with the negative terminal
of the power output.
2) Each digital input consumes approximately 15 mA.
FC610 supports Modbus RTU directly via a RS485 interface. The connection is as follows,
