The switching/solar protection actuator receives telegrams from sensors or other controllers via the KNX and switches electrical consumers. In the ETS, the electrical relay outputs can be set to shutter or switching operation.
In shutter operation, the actuator can control electrically operated blinds, shutters, awnings, skylights, ventilation flaps or similar hangings suitable for mains voltage with its relay contacts. Alternatively, the actuator switches electrical loads in switching operation, for example, lighting systems or door openers. Each relay output has bistable switching relays that are supplied with bus voltage, allowing defined preferred positions on bus voltage failure/recovery and after an ETS programming operation.
The functional properties that can be set in the ETS include, for example, independently configured move times in shutter operation, extended feedback functions, assignments to up to 5 different safety functions, an extensive solar protection function and integration in scenes, blocking functions and forced controls. In addition, central control of the shutter output is possible via up to 6 central functions. In switching mode, functional features include opener or closer operation, extensive time functions, logic operations, scenes, monitoring functions, operating hours counter, blocking functions or forced controls. 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 outputs, 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 outputs 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 shutter or dimming outputs 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 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.
