Module to control a relay contact over the DALI bus (DT7) for luminary installation and flush-mounted box. 59x33x15mm. Protection class IP20. DALI current consumption 2.7mA. Compact relay module for direct control of 230V loads over DALI. Loads without DALI input are easily integrated in a DALI circuit. Loads can be switched on/off by DALI commands. The device function complies with the standard for DALI Device Type 7 – switching function (as of Firmware 2.0). Adjustable characteristic for power-up and bus power failure. The DALI RM8 is powered over the DALI bus. No additional power supply is required. Zero passage switch-on. The module represents a bus user and is therefore addressable. Configuration via DALI Cockpit PC software. DALI functions and command set: The DALI RM8 can integrate loads on the DALI bus and can then switch them on/off. The DALI RM8 is a control device for non-dimmable loads based on the DALI specifications in IEC 62386-208 (Device Type 7). Accordingly, the switch characteristic is determined by comparing the virtual dim level (VDAP) with 4 switching thresholds. The virtual dim level (VDAP) corresponds to the dim level of a DALI electronic ballast with its corresponding characteristics (limited by MINLEVEL and MAXLEVEL, dimming speed limited by fade time and fade rate). There are 2 switching thresholds in each dimming direction and they are used for comparison with the virtual dim level. Only the applicable switching threshold for the current virtual dimming direction is evaluated. A threshold with the value MASK is inactive and is not used in the comparison. Switch-on/off delays can be implemented with fading. The DALI RM8 is powered from the DALI bus. The relay response to a bus power failure can be configured by the SystemFailureLevel (no change, ON or OFF, factory setting: ON). The power-on response after applying bus power can be set with PowerOnLevel.
