Data communication
For data communication with a central control system
the
XRW1-4
relay is provided with a serial interface
RS485. Simplified and fast reading and changing of
parameters and measuring values can be achieved by
HTL/PL-Soft4.
The
XRW1-4
can be connected to other units of the
P
ROFESSIONAL

via interface. If
there are more than one relay in the system, the last re-
lay of the chain has to be provided with a line termina-
tion resistor.
