Device Supply

The device is powered via terminal blocks with CAGE CLAMP
The device supply generates the necessary voltage to power the electronics of
the device and the internal electronics of the connected I/O modules.
The fieldbus interface is galvanically separated to the electrical potential of the
device.

Fieldbus Connection

Connection to the fieldbus is by two RJ-45 connectors. The EtherCAT
supports a transmission speed of 100 Mbit/s and full-duplex operations.
The RJ-45 socket on the fieldbus couplers are wired per the 100BaseTX
standard. The colors of the wires should correspond to the assignment T568B
according to TIA/EIA-568-B.
A fully-shielded twisted pair cable (SF/FTP, S/FTP, S/UTP) is exclusively
recommended as the connecting cable. The maximum length of the transmission
cable is 100 m, if transmission of Class D is achieved in accordance with EN
50173.
The socket is arranged physically lower, allowing the coupler to fit in an 80 mm
high enclosure after plug connection.
