The Weinzierl dimmer family has been expanded eightfold: the new KNX Blue IO 55X product range offers four PWM outputs for dimming LEDs with functions for RGB/RGBW and TW (Tunable White). Control is wired via KNX TP or KNX IP or wireless via KNX RF. Each model is available in variants for constant current or constant voltage. A particularly practical feature is the design that provides power supply for both the dimmer and the lamps themselves via PoE++.

All variants offer powerful sensor functions, including scenes, staircase automation, snooze function and sequencer.

Two push-buttons and three LEDs enable local operation and visualisation of the respective device status.
