GIRA Dimmer/actuator 202500 1 pc(s)

Dimmer actuator 4-way comfort for KNX 4 x 225 W/VA Features: - Dim actuator with integrated bus connection. - Switching and dimming incandescent lamps, HV halogen lamps, dimmable HV LED lamps, dimmable compact fluorescent lamps, dimmable inductive transformers with low-voltage halogen or low-voltage LED lamps, dimmable electronic transformers with low-voltage halogen or low-voltage LED lamps. - Automatic or manual selection of the dimming principle appropriate to the load. - Safe from idling, short-circuit and over temperature. - Manual operation of the outputs independent of the bus. - Temporary status display can be activated, linking via communication object via several actuators possible. - Parallel connection of several outputs for dimming larger lamp loads or power extension via power accessories. - In order to simplify the configuration, all available dimming channels can be assigned to the same parameters in the ETS and therefore be parameterized identically. - Up to 6 central functions for the common control of all dimming channels with switching, dimming and value objects. - Up to 8 independent logic functions for the implementation of simple or complex logical operations. - Active return or status messages can be delayed globally after a voltage recovery or after an ETS programming process. Dimmer outputs - Independent switching and dimming of the dimming outputs. - Specification of the load start and definition of the dimming principle possible: Universal (with automatic calibration procedure), electronic transformer (capacitive / phase section), conventional transformer (inductive / phase section), LED (phase section) or LED (phase section). - Dimm characteristic for each channel for adaptation to the respective connected load in the time range and value range configurable. - Adjustment of the dimmable range is possible (switch-on brightness, basic brightness; alternatively: Lower dimming limit and upper dimming limit). - Adjustable response when receiving an absolute brightness value (dimming, starting, fading). - Response can be set for relative upward dimming in the switched-off state (switch on channel, no reaction). - Central control function via up to 6 switching objects, 6 dimming objects and 6 value objects and group feedback. - Feedback Switching: Active (when changed or sent cyclically to the bus) or passive (object readable) feedback function. - Feedback Brightness value: Active (when changed or sent cyclically to the bus) or passive (object readable) feedback function. - The type of update can be set for active feedback objects (when the input object is changed or the feedback value is changed). This means that they can be adapted to individual visualizations. - Feedback signals for short circuit, overload/mains power failure and load start (KNX compliant and extended). - Response in case of bus voltage failure/return and after an ETS programming process can be set for each output. - Logical linking function for each output. - Lock function can be parameterized for each channel. Alternative forced position function separately for each output. - Time functions (on, off delay). - Staircase light function with pre-warning function by time-controlled reduction of the lighting or activation of a permanent lighting. - Staircase function with time extension or variable terpenthouse time assignment via communication object. - Soft-ON function and soft-OFF function can be set. - Automatic switch-off can be set if the brightness value is less than X % (with individual delay time). - Integration in light scenes possible: Up to 64 internal scenes can be parameterized for each output. - Delay time for scene retrieval configurable. - Dimming behavior can be adjusted when calling a new scene (start, dim, fade). - Visual feedback when saving a scene. - Extended scene recall. - Operating hours counter can be activated individually for each output. - Operating hours counter as forward counter (with optional limit) or reverse counter (with optional start value). Logic functions - The device has eight internal logic functions. - Logic gate (AND, OR, exclusive AND, exclusive OR, each with up to 4 inputs). - 1-bit to 1-byte converter with input filter, blocking object and specification of the output values. - Lock element with filter and time functions and lock object. - Comparators for values with nine different input data formats and many comparison operations. - Limit switches with hysteresis with upper and lower thresholds for nine different input data formats, including specification of the 1-bit output values. - The logic functions have their own KNX communication objects and can process telegrams of the actuator or other bus devices. Notice: - VDE-approval according to EN 60669-1, EN 60669-2-1. - The maximum connected load depends on the selected operating mode (phase or phase section). More detailed information can be found in the user manual. - Performance enhancement with GIRA power add-ons. - Only use up to 95% of parallel connected outputs. Do not connect compact fluorescent lamps to parallel switched dimming outputs. Do not extend the parallel dimming outputs with additional power. - Mounting on DIN rail. - KNX Data Secure compatible. - Quick download of the application (long frame support). - Firmware updates are possible with the GIRA ETS Service APP (additional software). Scope of supply: - Connection and branch terminal for KNX included.
