KNX line coupler 2142 REG
ETS-product family: System component
Product type: Line coupler
Series embodiment (SE)-device (2 units)
Function: The coupler connects two KNX lines together and guarantees electrical isolation between these lines.
The exact function of the device is defined by the address and the selected application.
Line coupler: Connection of a line and a main line with or without a filter function.
The coupler is physically assigned to the secondary line (here: line).
Backbone coupler: Connection of a main line and a backbone line with or without a filter function.
The coupler is physically assigned to the secondary line (here: main line).
Amplifier: Preparation and repetition of telegrams on a line, no filter function. Subdivision of a line into max. 4 independent line segments
= max. 3 line repeaters per line connected in parallel. A separate power supply including a choke is required for each line segment.

Technical data:
Power supply: 21 – 32 V DC via the primary line
Power consumption
Primary line: approx. 6 mA
Secondary line: approx. 8 mA
Connection: KNX connecting terminal for primary and secondary line
Ambient temperature: –5°C ... +45°C
Storage temperature: –25°C ... +70°C
Protection: IP 20 in accordance with EN 60529
Protection class: III in accordance with EN 61140
Note:
• The filter tables are stored in a non-volatile memory (flash). This means that the stored addresses are not lost after a bus voltage failure
and that no internal backup battery is required.
