DALI relay output device for switching lamps for mains voltages up to 230/240 V. The device has a controllable relay contact on the output side. The maximum total current via this contact is designed for 4 A (at cosphi=1). The power is only supplied via the DALI control line (no mains connection) with a current consumption of 20 mA (10 DALI loads). If the power supply fails, the relay drops out. Consumers and the DALI control line on the input side are connected via external cables. The DALI input is voltage-proof against 230/240V external voltage. White plastic housing made of flame-retardant polycarbonate, halogen-free. The device is installed near the load to be switched or in lights, ceilings or cable ducts at a permissible ambient temperature of 0..50° C. Protection class IP20, dimensions: 41 x 30 x 11 mm, weight: 0.1 kg
