LDALI-RM5 / LDALI-RM6 Relay Modules

UL Listed Product

The LDALI‑RM5/RM6 Relay Modules enable the control of consumers without DALI interface. Typical application scenarios are the integration of non-DALI luminaires (with 1 – 10V or no control interface) or other loads like fans in toilets or washrooms and motors for partition walls or screens in DALI lighting applications.

The built-in relay contact can be used for currents of up to 10 A or loads of up to 2 500 VA, respectively. It supports a wide voltage range of 120 – 277 V AC and up to 30 V DC. Zero cross switching technology is used to be able to handle the large in-rush currents typically found in lighting applications. For legacy dimmable ballasts, the LDALI-RM modules are also equipped with a 1 – 10 V interface, which can be used together with the relay contact to control these types of loads via DALI.

Together with the LOYTEC DALI controllers or LROC‑40x room automation controllers, the LDALI‑RM modules act as programmable switching output modules. The integration of the module in the DALI network follows the same simple steps as the integration of a DALI lamp. The device supports the DALI specification IEC 62386‑208 (Device Type 7, “switching function”) for non-dimmable loads and the DALI specifications IEC 62386‑206 (Device Type 5, “converter”) for loads dimmable via the 1 – 10 V interface, respectively (max. 50 mA current sink). The LDALI‑RM modules are directly connected to a DALI channel and also supplied with energy by that channel.

As a unique safety feature, the relay state for fault conditions can be configured: In case of a loss of power on the DALI bus, the relay will switch to the position as defined with the DALI configuration register “System Failure Level”.

The LDALI-RM module comes with two housing options: While the LDALI-RM5 is designed for installation in distribution boxes or behind standard plugs in installation boxes, the LDALI-RM6 allows installation on US-style fixtures or junction box ½’’ knockouts (“spud-mount”).
