ABB sa-m-0.4.1 Switch Actuator Module 4-G 16A

ABB SA-M-0.4.1 Switch Actuator I/O, 4-fold, 16 A, part number 2CDG510006R0011, is a Free@home switch actuator that provides four independent relay outputs for controlling lighting and other AC loads from a single module within the ABB Free@Home ecosystem. It is powered from the Free@Home bus (24 V DC) and draws about 12 mA as a bus participant, simplifying wiring alongside the control backbone. Each channel is rated for up to 16 A and intended for 127–230 V AC loads at 50/60 Hz, making it suitable for a wide range of lighting scenarios. The device accounts for switching transients with a turn-on peak of up to 200 A (600 μs), which helps protect connected fixtures and avoid nuisance tripping on inductive loads. The MDRC variant is designed for 4-gang installation, enabling four separate loads to be controlled either individually or in coordinated scenes via Free@Home automation software. Typical use cases include multi-circuit lighting control in single-family homes or small offices, where centralized automation, ambient lighting scenes, and manual override capabilities are desired through ABB’s Free@Home controllers and interfaces. The SA-M-0.4.1 is part of ABB’s Free@Home switch actuator family and is commonly referenced in retailer catalogs under 2CDG510006R0011, validating its 4-channel, 16 A per-channel capability within a 4-gang module.
