Description
Line/area coupler
The ekinex® EK-BA1-TP line/area coupler allows the coupling
of a KNX bus main line with a KNX bus secondary
line. The device provides the galvanic isolation between
the two connected lines. Thanks to its flexibility, the coupler
can be used as a line coupler to connect a secondary
line with a main line or as an area coupler to connect a
main line with a backbone line. The main task of the device
is filtering the traffic according to the installation place
in the hierarchy or according to the built-in filter tables
for group oriented communication. The device provides
support for long messages (up to 250 bytes) and a configurable
pushbutton for the activation of special functions
which are helpful during installation, run time operation
and troubleshooting. 6 LEDs accurately display the bus
status on each line. This helps identifying common communication
problems due to bus load or retransmissions
on both lines. The device is powered by the KNX bus line
with SELV voltage 30 Vdc and does not require any auxiliary
power supply.
