KNX TP Blue IO 550 CV secure - 4-fold Dimmable LED Actuator for Constant Voltage

KNX TP Blue IO 550 CV secure is a compact RGB / RGBW / Tunable White dimming actuator with 4 PWM outputs. The dimming actuator can be used, for example, for LED panels or strips with RGB / RGBW / Tunable White configuration or as 4 independent dimmer channels. Each configuration allows channel control via switching, relative dimming, and dimming value. Various comfort functions are also integrated, including scenes, sleep fade, stair lighting, and sequencer. Two buttons and five LEDs enable local operation and display of the device status. In addition to the output channels, the device includes 16 independent functions for logical or timed control. The device supports KNX data security.
