The universal dimming actuator operates according to the leading or trailing edge dimming principle and enables switching and dimming of incandescent lamps, HV halogen lamps as well as LV halogen lamps with conventional transformers and Tronic transformers as well as dimmable HV LEDs and LV LEDs with electronic or conventional transformers.

Provided it supports the load, the characteristic of the connected load can be automatically measured and a suitable dimming process can be set. Alternatively, a fixed dimming process can be configured by setting ETS parameters. This procedure is required for loads that do not enable automatic measuring. A dimming output is available.

The device enables a switching and brightness state response of the connected load to the KNX. A short circuit and load failure can also be reported to the KNX.

Aside from the dimming output, the device has 3 additional inputs. Potential-free switches, pushbuttons or other contacts (e.g. magnetic contacts) can be connected to these inputs. The signals of the inputs are read in via a common reference potential at the device. Depending on how the ETS is configured in the application for switches, pushbuttons or contacts, inputs 1 and 2 either act internally on the dimming output or separately on the KNX bus. Input 3 always acts on the KNX bus if required. When acting internally, inputs 1 and 2 directly operate the dimming output in a specified configuration. When acting on the KNX, telegrams for switching or dimming, for blind control or value transmitter application (dimming value transmitter, light scene extension unit, color or color temperature value transmitter) can be sent individually from the inputs.

In addition to the dimming mode and the inputs, the device has 8 internal logic functions for realizing simple or complex logic operations.

The electronics of the device are supplied via the bus voltage (no additional supply voltage required).

The screw terminals on the device are designed for connecting untreated solid conductors, flexible conductors without ferrules 0.5 to 4 mm² and flexible conductors with ferrules 0.5 to 2.5 mm². The KNX connection and the 3 binary inputs are connected via a preassembled control line YY6x0.6.

The device is designed for installation in suitable device boxes (recommendation: electronic device box with partition).

The device is KNX Data Secure-enabled. KNX Data Secure protects the building automation systems against manipulation and can be configured in the ETS project. For secure commissioning, it is mandatory that a device certificate be affixed to the device. As part of the installation process, the device certificate must be removed from the device and kept in a safe place.

The device can be updated. Firmware updates can be conveniently installed using the Siemens firmware download tool.
