If sufficient number of analog voltage inputs are available in the IED, alternative two
with separate inputs for STTIPHIZ and ROTIPHIZ are recommended.
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.
The default parameter settings are used for the pre-processor block.
It is possible to connect two REG670 IEDs in parallel to the REX060 injection unit in
order to obtain redundant measurement in the two IEDs. However, at commissioning,
both IEDs must be connected during the calibration procedure.
It is important that REX060, REX061 and REX062 chassis are solidly
earthed. Protective earth is a separate 4 mm screw terminal that is a
part of the metallic chassis.

Making the optical connections
6.3.1
Connecting station and process bus communication
interfaces
The IED can be equipped with an optical ethernet module (OEM), see Figure
needed for IEC 61850 communication and a serial communication module (SLM),
see Figure
for LON, SPA, IEC 60870–5–103 or DNP3 communication. For the
locations of rear-side connectors, see section
.
•
Optical ports X311: A, B (Tx, Rx) and X311: C, D (Tx, Rx) on OEM are used for
IEC 61850-8-1 communication. Both ports AB and CD shall be connected when
redundant IEC 61850-8-1 communication is used. Port C, D is used for IEC
61850-9-2LE communication. Connectors are of ST type. When OEM is used,
the protection plate for the galvanic connection must not be removed.
•
Optical port X301: A, B (Tx, Rx) on SLM module is used for SPA, IEC
60870-5-103 or DNP3 communication. Connectors are of ST type (glass) or
HFBR Snap in (plastic).
•
Optical port X301: C, D (Tx, Rx) on SLM module is used for LON
communication. Connectors are of ST type (glass) or HFBR Snap in (plastic).
The optical fibers have Transmission (Tx) and Reception (Rx) connectors, and they
should be attached to the Tx and Rx connectors of OEM and SLM module (Tx cable
to Rx connector, Rx cable to Tx connector).
