Pin assignment of the T-adapter cable 7XV5104-3AA00
The T-adapter cable 7XV5104-3AA00 distributes both electrical output signals at the 9-
pin sub-D socket X1 to two separate electrical buses. The connection to each 6
SIPROTEC 4 devices is realized with further Y-bus cables. Through switching both
electrical output signals to one common input maximal 12 SIPROTEC 4 devices can be
time synchronized by one input signal.

High precision second pulse for 7SD52
At X1 of the Sync.-Transceiver two semiconductor outputs are available. PIN 1/3 is
used for the time synchronization telegram and PIN 4/8 is used as second-pulse output
for the GPS-application of differential relay 7SD52.
To connect X1 with Port A (IRIG-B input) of the 7SD52 7XV5105 cable should be used.
Both signals are transmitted to the relay by this 4 wire cable.
Binary input BI2 (X5)
Via the binary input BI2 with a delay time of approx. 5 ms an electrical pulse can be
distributed via the electrical outputs of X1 or via the relay output K2 (X6). This input may
not used for very fast signals and the length of the input pulse must be greater than 5
ms to guarantee a safe recognition of the input signal. Via a jumper X100 the pickup
voltage can be increased from 17 V to approx. 70 V.
Electronic relay output K2 (at X6)
Relay output K2 is a fast electronic load relay, which allows switching a battery voltage
from 24 V – 250 V DC to the binary inputs of the SIPROTEC devices. The maximum
load current is 100 mA.
