LDALI-RM8 8-output 16A DALI BUS Relay Module

The LDALI-RM8 relay module enables the control of standard loads via DALI. Typical application scenarios include the integration of non-DALI luminaires or other loads such as fans in restrooms or bathrooms, motors for partition walls or screens, and fire dampers in DALI lighting applications. The device provides 8 integrated relay contacts, which can be controlled individually via separate DALI addresses, provided the corresponding digital input is open. Closing this input will always switch the relay on (override). Each relay provides a switch that indicates the status and can be used to switch the relay manually (installation and maintenance). The built-in relay contacts can be used for currents up to 16 A. They support a wide voltage range of 120 - 277 V AC and up to 30 V DC. The relays are suitable for loads with high inrush currents.

Together with LOYTEC L-DALI controllers or LROC-40x room automation controllers, LDALI-RM8 devices act as programmable switching output modules. Integrating the module into the DALI network follows the same simple steps as integrating DALI luminaires. The device supports the DALI specification IEC 62386-208 (Device Type 7, "switching function") for non-dimmable loads. LDALI-RM8 is externally powered with 24 V DC or 85 - 240 V AC.

As a unique safety feature, the relay status for fault conditions can be partially configured. In case of power loss on the DALI bus, the relays will switch to the position defined in the DALI configuration register "System Failure Level". In case of power loss on the 24 V DC / 85 - 240 V AC, the relays maintain their state until a "Power On" occurs, at which point they will switch to the state defined in the configuration register "Power On Level".

LDALI-RM8 is intended for use in an electrical cabinet.

LDALI-RM8 is DALI-2 certified.
