ABB da-m-0.4.1 Dim Actuator 4-Gang Modular System

ABB free@home DA-M-0.4.1 Dimming Actuator is a four-gang modular DIN-rail device that enables four independent dimming channels for ABB-free@home lighting installations, letting you control multiple dimmable loads from the same module. Built as an MDRC construction type module, it mounts on a standard DIN rail and runs on 230 V AC mains, with each channel designed to dim connected loads through the free@home controller. Local operation is provided on the device via LED indicators and push-buttons: a brief press toggles On/Off, while a longer press performs dimming adjustments, and during commissioning the unit can be identified within the system. The DA-M-0.4.1 is documented in ABB's free@home materials as the four-gang dimming actuator, underscoring its role in building scalable, multi-channel lighting control within a single compact DIN-rail module that integrates with the ABB-free@home software to support scenes and automation routines.
