Communication via KNX with digital electronic control gear (ECG) featuring a DALI interface. Two DALI outputs with DALI-2 certification according to IEC 62386-101 and 103, each capable of connecting up to 64 DALI ECGs via a DALI bus line. Integrated power supply for an input voltage of AC 110 to 240 V, 50/60 Hz or DC 120 to 240 V to power the gateway electronics and DALI outputs. Support for ECGs types 0, 1, 2, 3, 4, 5, 6, 7, and 8 according to EN 62386 Edition 1 and Edition 2 (DALI-2). DALI output voltage approximately 19 V, potential-free and short-circuit proof. Foreign voltage detection at startup to check for incorrect mains voltage at a DALI output. LED display to show operating states and error messages. Button to switch between bus and direct operation. A pair of buttons per DALI output for the simultaneous switching on or off of all connected lights in direct operation. An LED per DALI output to indicate the switching state of all connected lights in direct operation. Configurable behavior in case of bus voltage failure (standalone operation). Control (switching, dimming, and setting dimming values) of all connected lights together in broadcast operation. Reporting and display of lamp and ECG faults per lighting group and per DALI participant. Single-stage or two-stage timer operation. Integrated scene control for up to 32 scenes. Assignment of DALI ECGs to individual groups with testing capability for ECGs, groups, and scenes using the ETS during the commissioning of the gateway. Ability to replace defective DALI ECGs without software (ETS). Integrated KNX bus coupler with a maximum of only half the standard bus load (5 mA). KNX bus connection via bus terminal. Rail-mounted device for installation on TH35 DIN EN 60715 mounting rails.
