Module for controlling a relay contact via the DALI bus (DT7) for luminaire installation and flush-mounted socket. 59x33x15mm. Protection class IP20. DALI current consumption 2.7mA. Compact relay module for direct control of 230V AC loads via DALI. Easy integration of loads without a DALI input into a DALI circuit, the loads can be switched on and off using DALI commands. The device functions in accordance with the standard for DALI Device Type 7 - switching function (from firmware 2.0). Adjustable behavior for power-up and for loss of bus supply. The DALI-RM8 is supplied via the DALI bus, no additional supply is required. Switching on at zero crossing. The interface represents a participant on the bus and can be addressed accordingly. Configuration via DALI Cockpit PC software. DALI functions and command set: The DALI-RM8 offers the option of connecting loads to the DALI bus and then switching them on and off. The DALI-RM8 is a control device for non-dimmable loads based on the DALI specification IEC 62386-208 (Device Type 7). Accordingly, the switching characteristics are determined by comparing the virtual lamp power level (VDAP) with 4 switching thresholds. The virtual lamp power level (VDAP) corresponds to the dimming value of a DALI ECG and is subject to the corresponding properties (limitation by MINLEVEL and MAXLEVEL, dimming speed by fade time and fade rate). There are 2 switching thresholds for each dimming direction, which are used for the comparison with the virtual lamp power level. Only the switching threshold valid for the current virtual dimming direction is evaluated. A threshold with the value MASK is inactive and is not used for comparison. Fading can be used to implement switch-on and switch-off delays. The DALI-RM8 is powered by the DALI bus. The behavior of the relay in the event of a bus power failure can be configured using the SystemFailureLevel (no change, on or off, factory setting: on). The switch-on behavior after the bus power is applied can be set using the PowerOnLevel.
