Siemens SIPROTEC 5 Series

•
Ethernet Modules
Application: Ethernet-based communication to the substation automation technology via substation-
control protocols (for example, IEC 61850 and DNP3)
– Secure communication to DIGSI 5
– Communication between the devices (IEC 61850-GOOSE)
– Synchrophasor protocol
The modules can be operated with or without an integrated switch.
•
Long-distance modules
Application: Direct protection interface communication over long distances using multimode or single-
mode optical fibers.
The designation of the modules corresponds to the following scheme, which is typically explained with the
module USART-AB-1EL. The module designation consists of 3 blocks.
1st block Type of module
USART = Serial module for short or long distance
ETH = Ethernet module
2nd block Unique code for the module in the product code of the device
The code consists of 2 letters.
3rd block Number and physical design of the connections
1 = 1 connection (1 channel)
2 = 2 connections (2 channels)
EL = Electrical connection
FO = Fiber-optic connection
LDFO = Long-distance transmission via optical fibers
