Akubela KXAC-B1R28A10 28-Channel 10A KNX Switch Actuator

Akubela KXAC-B1R28A10 28-Channel 10A KNX Switch Actuator

The Akubela KXAC-B1R28A10 is a high-density KNX switch module built for large-scale automation projects that need to control dozens of circuits from a single DIN rail device. With 28 independent relay outputs rated at 10A each, it consolidates lighting, power point, and small appliance switching for entire floors or wings of a building into one compact enclosure, reducing cabinet space and wiring complexity compared to multiple smaller actuators.

Key Features

• 28 independently switched relay channels, each rated for 10A resistive/inductive loads
• Standard KNX/EIB TP1 bus connection, fully parameterised through ETS software
• Manual override switching in addition to bus-commanded control
• Timed and scheduled operation with configurable on/off delay per channel
• Built-in logic gate functions (AND, OR, XOR) for advanced automation sequences
• Scene storage and recall across grouped channels
• Real-time status feedback reported back to the KNX bus for every output
• DIN rail mounting for tidy installation inside distribution boards
• Compliant with EN60947-4-1, EN60669 and EN50090-2-2 electrical safety standards

Where It Fits

This actuator suits commercial fit-outs, hotels, apartment towers and large luxury homes where a single KNX line needs to manage a very high channel count without stacking numerous 8- or 12-way modules. Typical uses include general lighting circuits, feature and accent lighting groups, exhaust fans, non-dimmable loads, and switched power outlets across offices, function rooms, corridors and multi-zone residences. Because each channel reports status and supports scene and schedule logic, it also works well as the switching layer behind a central automation panel or building management system, letting integrators combine lighting scenes, time schedules and simple logic conditions without needing extra controllers.

What's in the Box

• 1 x Akubela KXAC-B1R28A10 28-channel switch actuator
• DIN rail mounting clips (pre-fitted)
• KNX bus connection terminal
• Quick installation reference

Frequently Asked Questions

Does this actuator need a separate power supply?
The device is powered from the KNX bus for its logic and communication, while the switched outputs use the mains supply connected to each load circuit, so a standard KNX bus power supply on the line is required.

Can channels be grouped for scenes?
Yes, channels can be grouped so a single scene or schedule command switches multiple outputs together, which is useful for zoned lighting or multi-circuit power control.

Is ETS required to commission the device?
Yes, the actuator is configured using standard ETS software, allowing installers to set channel behaviour, delays, logic functions and status objects to suit the project.
