Assignment of the T Adaptor Cable 7XV5104-3AA00
The T adaptor cable 7XV5104-3AA00 provides the 2 electrical channels of the socket X1, at the pins 1/3 and
4/8, for 2 separate buses for time synchronization.
You cannot connect any protection devices directly to either of the output sockets of the T adaptor cable. The
output sockets of the T adaptor cable serve as an interface for one line each of the Y bus cables of the type
7XV5104-0AAxx. With the downstream cascading of these Y bus cables, you can synchronize up to 6 protec-
tion devices per line using the time telegrams. This means that one Sync-Transceiver can handle a maximum
of 12 protection devices. When you switch on the DIP switch S1/3, you couple both switching outputs of the
socket X1 of the Sync-Transceiver. In this configuration, you can synchronize up to 12 protection devices from
one common time-telegram source.
