2. It is possible to use a mixed connection that requires only two IED voltage channels for
both ROTIPHIZ and STTIPHIZ. REX060 outputs are connected in series. This connection is
not recommended and can be used only in applications where it is prove the possibility to
use it. the use of this connection leads to reduced performances of both ROTIPHIZ and
STTIPHIZ.

Figure 43: Connection to IED with two analogue voltage inputs
Some settings are required for the analog voltage inputs. Set the voltage ratio for the inputs
to 1/1, for example, VTSecx = 100 V VTPrimx = 0.1 kV
The analog inputs are linked to a pre-processor block in the Signal Matrix Tool. This pre-
processor block must have the same cycle time, 8 ms, as the function blocks for STTIPHIZ and
ROTIPHIZ.
