The switching actuator receives telegrams from sensors or other controllers via the KNX and switches an electrical consumer. Functional features include opener or closer operation, extensive time functions, logic operations, scenes, monitoring functions, operating hours counter, blocking function and forced control. In addition, the switching status of a relay output can be reported back. Central switching of the switching outputs via up to 6 central functions is also possible in switching mode.

Aside from the relay 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 relay output or separately on the KNX bus. Input 3 always acts on the KNX if required. When acting internally, inputs 1 and 2 directly operate the switching output in an adjustable 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 switching 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 via the Siemens firmware download tool.
