KNX IO 532.1 secure KNX dimming act. 1-fold PWM with relay

The KNX IO 532.1 secure is a compact combined dimming/switching actuator with 1 PWM dimming output for LEDs and 1 bistable relay output.

The dimming actuator can be used e.g. for LED panels or stripes. Besides controlling the dimmer by switching, rel. dimming and dimming value, several optional functions are integrated, including scenes, automatic, slumber function or staircase light.

The switching actuator provides the function for universal outputs including scene control, timer, staircase lighting and heating valves (PWM for thermoelectric valve drives).

Two push buttons and three LEDs allow a local operation and a visualization of the device state.

In addition to the output channels the device includes 16 independent functions for logic or timer control.

The device supports KNX Data Security.
