Uhlenbrock Intellibox 3: Features & Buying Guide
The Intellibox 3 controls DCC, mfx, Motorola and Selectrix vehicles on two-rail and three-rail layouts. Two throttles, a touchscreen, a 4 A booster, LocoNet, Wi-Fi and extensive automation functions provide a versatile system foundation for small and large model railway layouts.
One command station for new and older digital components
What Is the Uhlenbrock Intellibox 3?
The Intellibox 3 combines a command station, booster, throttle, programmer, control panel, feedback monitor and computer interface in one device. Its two throttles provide direct access to two locomotives. The colour touchscreen displays locomotive names, function symbols, turnouts, signals and other operating information.
Locomotive and function decoders can use DCC, mfx, Motorola and Selectrix. Turnout and switching decoders are addressed using DCC or Motorola. The command station is therefore particularly interesting when older Märklin vehicles, modern DCC locomotives and accessory decoders from different manufacturers are operated on the same layout.
The integrated booster provides an adjustable output current of up to 4 amps. This allows the cut-off threshold to be adapted to small gauges or higher power requirements. Large layouts should still be divided into several booster districts so that a short circuit does not stop the entire railway.
The Intellibox processes up to 9,999 decoder addresses and up to 128 speed steps. A RailCom receiver, routes, a model clock, LISSY and MARCo functions and DirectDrive support sophisticated operating sequences and automated layouts.
USB and Wi-Fi allow the command station to communicate with computers, smartphones, tablets and compatible control software. Backups and updates can be managed through the intended storage and network interfaces.
A proven system environment with modern controls
When Does the Intellibox Demonstrate Its Strengths?
Direct Operation
Keep Two Trains Under Control Simultaneously
The two throttles make train crossings, shunting and the parallel operation of several locomotives easier.
LocoNet Expansion
Connect Controllers and Modules Around the Layout
Handheld controllers, boosters, feedback modules and switching modules are connected along the layout through one shared network.
Existing Layouts
Continue Using Existing Uhlenbrock Equipment
Many LocoNet components from earlier Intellibox generations can continue to be used after their compatibility has been checked.
Automation
Combine Feedback and Routes
Occupied tracks, train numbers and switching commands can be used for staging yards, block operation and operating sequences.
Several Operators
Add IB-Control and DAISY II
Additional fixed or mobile operating positions provide more freedom of movement and distribute tasks during layout operation.

Pay Particular Attention To
Adapt the track voltage and booster output to the vehicle and decoder.
H0, H0e and H0m
The range of supported protocols is particularly useful in H0. DCC, Motorola and mfx vehicles can operate together, while LocoNet handles expansion with control panels and feedback.
Suitable Components
Intellibox 3, IB-Control 3, DAISY II and LocoNet modules.
Pay Particular Attention To
Where possible, power accessories separately from the track supply.
Gauge 0, Gauge 1 and Gauge G
Large motors, sound, smoke and lighting require greater power reserves. The layout should be divided into several output and short-circuit districts.
Suitable Components
Intellibox 3, Power 70 or Power 40 LN and LocoNet distributors.
Pay Particular Attention To
Plan cable cross-sections, track feeds and isolation points carefully.

Avoid potential faults at an early stage
Common Planning Mistakes with the Intellibox and LocoNet
Using Four Amps as One Large Circuit
Several booster districts improve operating reliability and troubleshooting.
Planning the IB-Control as a Command Station
The additional device always requires a LocoNet-compatible digital command station.
Confusing LocoNet T and LocoNet B
Handheld controllers, boosters and power supplies must be connected to the intended bus.
Programming Modules Without an Address Plan
Duplicate addresses make feedback, routes and later maintenance more difficult.
Failing to Test Wi-Fi Coverage
Metal frames, walls and long distances can interfere with wireless connections.
Reusing Older Components Without Checking Them
Firmware, connector assignments and supported functions must be compatible.
