Why choose it

The ALC100 provides efficient telegram filtering and routing, ensuring that only relevant data crosses between lines or areas. This reduces bus load and improves overall system performance. Its compact DIN rail design allows easy integration into distribution boards.

Ideal use cases

• Large KNX installations requiring segmentation into lines and areas
• Smart home and building automation systems
• Projects where bus load management is critical

Good to know

The coupler is powered directly from the KNX bus, eliminating the need for an additional power supply. Configuration is done via ETS, the standard KNX engineering tool. The two LEDs provide visual status of bus and filter operation.
