KNX IO 530

The KNX IO 530 (1D2I) is a compact 230 V dimmer with 1 dimming output and 2 binary inputs. The dimming actuator can be used for dimmable electric lights supplied with 230 V mains. To cover a wide range of usable electric lights the KNX IO 530 can operate with trailing or leading edge dimming.

Besides controlling the light by switching, rel. dimming and dimming value, several optional functions are integrated, including scenes, automatic, slumber function, staircase light and sequencer. The inputs can be connected to conventional switches with an external voltage of 230 V. Two push buttons and three LEDs allow a local operation and a visualization of the device state. In addition to the output and input channels the device includes 16 independent functions for logic or timer control.
