Peakanalyzer Installation Manual Version 2.6
2.3.19.3 Connection of EtherCAT junction of type EK1521 for fibre optic cable
The EtherCAT junction as shown in Picture 17 of type EK1521 or EK1521-0010 or preferably
installed in the central Peakanalyzer base module. The EtherCAT junction with fibre optic of
type EK1521 allows a distributed mounting of Peakanalyzer terminals in the field with
multimode fibre optic cables 50/125 µm up to a distance of 2 km. The EtherCAT junction with
fibre optic of type EK1521-0010 allows distances up to 20 km with singlemode fibre optic cable
9/125 µm.

The connection of the EtherCAT branch is done via a SC-Duplex connector at socket X1. The
run LED shows the state of the EtherCAT branch. A further LED shows the Link and Activity
state. One Peakanalyzer base module can have multiple EtherCAT junction terminals of type
EK1521 equipped. At the port X1 one branched EtherCAT-Coupler of type EK1501 can be
connected as shown in Picture 18. The junction and the coupler must be connected with a fibre
optic cable.
The EtherCAT junctions, coupler and cables must be labeled for unique identification as
described in chapter 2.3.19.
