Roco 10820 Z21 Control Central Digital DCC and other Protocols

Digital driving enjoyment begins with the Z21 digital control centre!

This is where all the elements of your model railway system are brought together, whether it’s a standard handheld controller or modern touch operation via an app. All your inputs are translated as control commands for locos and turnouts, and output to the track.

This turns the control of multiple trains into child’s play!

Simple operation

The most important thing in a digital control system is the operation. It must be simple, intuitive and easy to use. You still want to maintain an overview of the entire system and fleet. This ease-of-use should also include configuring and setting the devices.

All these benefits are provided by our free of charge Z21 app.

Z21 App

Those who like driving their locos with an actual rotary control in their hand, don’t miss out with the Z21 multiMAUS either.The handheld controller that has been tried and tested hundreds of thousands of time can now also be enjoyed in complete freedom wirelessly in the form of the Z21 WLANMAUS. A combination of the Z21 app and Z21 multiMAUS is also a dream.
