KNX IO 534 (4D)
(Art. # 5314)
Dimming actuator with 4 PWM dimming outputs
Application with RGB / RGBW / Tunable White support
KNX IO 534 (4D)
Application area
The KNX IO 534 (4D) is a compact RGB / RGBW / Tunable
White dimming actuator with 4 PWM outputs.
The dimming actuator can be used e.g. for LED panels or stripes
with RGB / RGBW / Tunable White configuration or as 4 inde-
pendent PWM dimmer channels. Every configuration allows con-
trolling the channel by switching, rel. dimming and dimming
value.
Several comfort functions are integrated as well, including
scenes, slumber fading, staircase light and sequencer.
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 inde-
pendent functions for logic or timer control.
1. Installation and connection
The KNX IO 534 is designed for installation on a DIN rail (35
mm) with a width of 1 units (18 mm). An installation-friendly de-
sign with pluggable screw terminals helps to reduce the cost of
commissioning. It features the following controls and displays:
This device is powered by the KNX bus. An external power sup-
ply is not necessary.
The device is not working without bus power.

short. The selected channel is indicated by
a continuous light or cyclic flashing of LED Ch/M
❺
in green,
where the number of flash cycles indicates the number (A=1,
B=2, C=3, D=4) of the channel. On continuous light all channels
are controlled simultaneously in manual operation.
Pressing button A
❼
or B
❽
for a long time switches to manual
operation for the selected channel of the dimming actuator. This
