KNX, DIN rail


KNX line or area coupler for connecting a bus line with a secondary one. Mounting in distribution board on EN 60715 rail (2 modular units, each 18 mm). Powered by the bus line. To be used in KNX installations for home and building automation. Suppress device configuration on the sub line Enable or disable filtering of group messages Suppress device oriented messages Trace the traffic on the sub line Reduced number of retransmissions 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. • Housing in plastic material • Mounting on 35 mm rail (according to EN 60715) • Protection degree IP20 (according to EN 60529) • Safety class II • Weight 100 g • 2 modular units (1 unit = 18 mm)
