RAK8-MB Motherboard

The RAK8 motherboard with 8 slots is the basis for the RAK8 dimmer array.
The motherboard slots can be populated with a range of modules for trailing edge, leading edge, Dali and 0-10v dimming. There are also modules available for switching and blind control.
This unit can be used with the Rx-link wireless receiver with up to 16 channels per stack as each Rx-link will support 2 RAK8 motherboards. When used with a wired system utilising the RAK-link then up to 32 channels can be used. This means each RAK-link will support up to 4 RAK8s and many RAK-links can be used for a large system.
The RAK8 can be used in conjunction with he RAK4 products.
Programming is as standard using the free RASOFT pro software and the control is via RCM or WCM control panels for wireless or wired systems.
After programming the memory for the modules is stored withing the motherboard, no the modules, so modules can be interchanged without reprogramming.
The dimensions are 193x253x110mm and the weight is 3.5kg.

Rako RAK8-MB Motherboard – Flexible Wired Control for Smart Lighting

The RAK8-MB is Rako’s powerful and versatile MB motherboard, designed as the central component of a RAK8 wired lighting control system. Whether you’re specifying lighting for a new build, a high-end renovation, or a complex commercial project, the RAK8-MB is the best choice as it gives you the flexibility and reliability you need to build a fully custom, high-performance lighting solution.

What Is the RAK8-MB?

At its core, the RAK8-MB acts as the base for up to eight plug-in control modules, allowing for individual control and greater flexibility over different lighting channels. Each module slot is fully independent, meaning you can mix and match dimming and switching types to suit the exact requirements of each connected circuit—whether that’s trailing edge, leading edge, 0-10V, DSI, or DALI.

This makes the RAK8-MB incredibly adaptable for multi-zone lighting systems and large-scale installations. It connects via Rako’s reliable wired Rakom CAT5 network, ensuring fast, interference-free communication across the system, as well as a robust power supply.

Key Features:

• Holds up to 8 pluggable control modules – Choose the right module for each circuit
• Central wiring design – Clean and organised installation
• Compatible with Rako’s wired network – Uses CAT5 cabling for robust communication
• Scene-setting and dimming support – Enables advanced lighting control via wall panels or automation
• DIN-rail mountable – For easy installation within electrical enclosures
• Ideal for new-build and major renovation projects – Especially when wiring infrastructure is accessible

Who Is It For?

The RAK8-MB motherboard is perfect for professional electricians, smart home integrators, and designers working on wired Rako systems. It’s ideal in properties where wiring access is straightforward and the client wants the ultimate in performance and system reliability.

When installed as part of a RAK system, the RAK8-MB connects seamlessly with Rako’s wired wall controllers, sensors, and network bridges, creating a fully integrated lighting control solution. The result is smooth scene transitions, custom lighting moods, and the ability to automate or remotely control your lighting environment.

Why Choose the RAK8-MB?
