8.8.3.2 Connecting and setting voltage inputs
The SIM module of REX060 has two analog output channels that shall be connected
to two voltage input channels of the IED.
If both stator and rotor protection are used, there are two possible methods to perform
the connection.
1. The recommended connection requires four analog channels of the IED: two IED
voltage channels are used for the measured quantities for STTIPHIZ; two more
IED voltage channels are used for the measured quantities for ROTIPHIZ.

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 proved the possibility to use it. The use of this connection leads to
reduced performances of both ROTIPHIZ and STTIPHIZ.
