KNX TP Blue IO 551 CC secure - Dimmable 4-fold constant current LED actuator

KNX TP Blue IO 551 CC secure is a compact RGB / RGBW / Tunable White dimming actuator with 4 constant current dimming outputs. The dimming actuator can be used, for example, for LED panels or strips with RGB / RGBW / Tunable White configuration or as 4 independent dimming channels. Each configuration allows the channel to be controlled via switching, relative dimming, and dimming value. Various comfort functions are also integrated, including scenes, sleep fade, staircase light, 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 logic or timed control. The device supports KNX data security.
