Unrestricted
SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
1.3.1
Default Configurations
1.3.1.1 Redundant AUs, Voting by SCA-RS, Distance up to 15 m
•
Redundancy synchronization of function
diagram and of the periphery is executed by a
high speed link
•
A high speed link is essential with singular
periphery
•
The electrical connection between Ethernet
and SICAM RTUs component can be up to
100 m
•
Depending on the slots of the basic system
elements the socket connector for the H.S.L.
connection has to be selected (e.g. slot C0
socket connector HSL-C0)
The following socket connectors are
available: HSL-C0 and C1, in the small rack
CM-2832 and additional C4, C7, C10, C13 in
the large rack CM-2836
•
SCA-RS is connected to SICAM AK via the
socket connector SYS-IO on the SICAM AK
