Akubela 8-Channel 10A KNX Switch Actuator

Akubela 8-Channel 10A KNX Switch Actuator (KXAC-B1R8A10)

The Akubela KXAC-B1R8A10 is a DIN rail-mounted KNX switch actuator with eight independently controlled relay outputs, each rated for 10A of switching current. Powered directly from the KNX bus, it links lighting circuits, power points, small motors, and other resistive or capacitive loads into a KNX automation system, giving installers a compact, reliable building block for lighting and load-switching projects in homes, offices, and light-commercial fitouts.

Key Features

• 8 independently switched relay channels, each rated up to 10A
• Bus-powered design (no external power supply required) simplifies wiring
• Compact DIN rail housing suited to standard switchboard and distribution cabinet installation
• Manual override switches and per-channel LED status indicators for on-site diagnostics
• Configurable delayed on/off timing for each output
• Scene recall and central/group control functions for coordinated automation
• Live status feedback objects reported back to the KNX bus for monitoring and logic use
• Built-in overcurrent, short-circuit, and thermal protection for safer long-term operation
• Designed to CE, EMC and Low Voltage compliance requirements for KNX/EIB devices

Typical Applications

This actuator suits KNX integrators who need dependable, space-efficient switching for multiple circuits from a single DIN rail module. Common uses include controlling lighting zones room-by-room, switching general power outlets, driving small fan or pump motors, and forming part of scene-based or scheduled automation routines in residential and small commercial KNX installations. Because each channel can be programmed independently, a single unit can service several unrelated loads across a property.

Frequently Asked Questions

Does this actuator need its own power supply?
No. It draws its operating power directly from the KNX bus, so only the bus connection is required alongside the mains wiring for the switched loads.

Can I mix different load types across the eight channels?
Yes. Each of the eight outputs is switched and configured independently, so lighting, general power, and small motor loads can be assigned to different channels on the same unit.

What software is used to configure the actuator?
Like other KNX devices, it is commissioned and parameterised using standard ETS software, where scenes, delays, and central functions are set up.
