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.
