ABB SD/S8.16.1 Switch/Dim Actuator, 8-fold, 16A, KNX Modular Device

The ABB SD/S8.16.1 Switch/Dim Actuator is a professional-grade modular device engineered for the KNX building automation standard. This 8-fold actuator provides robust switching and dimming capabilities for lighting circuits, supporting a load of up to 16A per channel. Designed for seamless integration into smart building control networks, it offers precise control and reliable performance for complex electrical installations in both residential and commercial properties.

Advantages

This actuator stands out due to its high-performance design that combines switching and dimming functions in a single modular unit. By supporting 16A per channel, it provides the flexibility needed for various lighting loads, ensuring stability and longevity in demanding environments. Its compatibility with the KNX system allows for advanced automation scenarios, energy management, and centralized control, making it an essential component for modern, intelligent building infrastructures.

Suitable for

• Smart home lighting control systems
• Commercial office building automation
• Public building lighting management
• Integration into KNX-based building control networks

When it may not be suitable

This device is specifically designed for KNX systems and will not function as a standalone unit without a compatible KNX bus infrastructure. It is not intended for non-KNX electrical installations or for controlling loads that exceed the specified 16A current rating per channel.

Key specifications

• 8-fold switching and dimming channels
• Maximum load capacity of 16A per channel
• Modular DIN-rail mounting design
• KNX bus communication interface
• Compatible with standard lighting control protocols

How to use

The ABB SD/S8.16.1 must be installed on a standard DIN rail within a distribution board by a qualified electrician. Once physically mounted, the device is connected to the KNX bus line and the respective lighting circuits. Configuration is performed via the ETS software, where individual channels can be assigned specific addresses and functional parameters to match the requirements of the building automation project.

What to consider before purchase

• Ensure your existing infrastructure is based on the KNX standard
• Verify that the total load of your lighting circuits does not exceed 16A per channel
• Confirm sufficient space on the DIN rail within your distribution board
• Ensure professional installation by a certified technician

Usage recommendations

Regularly check the status of the device via the KNX software to ensure optimal performance. Avoid exceeding the maximum load per channel to prevent thermal stress on the internal components.
