Product Description
The ABB SD/S8.16.1 is a high-capacity 8-channel switch-dim actuator engineered for large-scale intelligent load control in commercial, industrial, and premium residential smart automation systems. As a flagship model in the SD/S series, it integrates advanced switching and dimming capabilities, paired with MDRC (Multi-Device Remote Control) technology, to deliver precise, synchronized management of diverse electrical loads—including high-power LED lighting arrays, incandescent/halogen fixtures, ventilation systems, small appliances, and other resistive, inductive, or capacitive devices.
Each of the 8 independent channels supports a robust 16A current capacity, enabling stable control of high-wattage loads while maintaining energy efficiency and flicker-free performance for dimmable lighting. Compatible with KNX TP (Twisted Pair) bus systems, the actuator seamlessly integrates into centralized building management systems (BMS), supporting remote control, custom schedule programming, and real-time synchronization with occupancy sensors, daylight detectors, or other KNX-enabled devices. The MDRC functionality enhances flexibility by allowing simultaneous control of multiple connected devices, facilitating complex scene activation (e.g., "office opening mode," "event venue dimming sequence") and streamlined energy optimization.
Featuring a space-efficient DIN-rail mounting design (16 division units, fitting standard 35mm DIN rails) and IP20 protection class, it is ideal for installation in control cabinets of large buildings, saving valuable space while ensuring durability for 24/7 indoor operation. Manual on-device push-button operation is supported for quick testing, maintenance, or emergency adjustments—even without bus voltage—providing on-site flexibility for installers and facility managers. Equipped with secure screw terminals (accommodating 0.5–2.5mm² copper conductors) and a flame-retardant polycarbonate housing, it meets international safety standards (UL94 V0, IEC compliance) for long-term reliability in high-demand environments.
Whether retrofitting large commercial complexes or building new smart infrastructures, the ABB SD/S8.16.1 combines 8-channel scalability, 16A high-load capacity, MDRC smart control, and broad load compatibility to deliver a cost-effective, high-performance solution for large-scale automation projects requiring synchronized switch-dim functionality.
