ROCO 10837 Digital Z21 Signal Decoder

Multi Scale

The Z21 signal DECODER is a universally usable DCC decoder for 2 to 4 complex light signals with a common plus. It is easy to use and future-proof thanks to its updatability.
Therefore it is ideal for complex LED signals.

Outputs for 2 to 4 signals

Depending on the complexity of the various signals, different numbers can be connected.

• 2 signals: 8 outputs can be used per signal.
• 3 signals: A signal with 8 outputs can be used. Two further signals with 4 outputs can be used for this.
• 4 signals: 4 outputs can be used per signal.

Many predefined signal types

Many predefined signal types with up to 24 signal aspects are available for easy configuration. This completely eliminates the need for a very time-consuming "function mapping", you only need to select the signal type. This can be done comfortably via the Z21 pro LINK or by writing a CV. The signal type can of course be set independently for each signal.

Over 30 types of signals are included, such as:

• Germany: H / V signals, Ks signals, Hl signals, blocking signals, ...
• Austria: main signals, type 1980 and 1954, advance signals, protective signals, shift signals, ...
• Switzerland: System L, System N, signals for the shunting service, ...
• France: Châssis-Écran A to H, Disque and Indicateur Direction
• Of course, additional signal types can be added using the update function via the Z21 pro LINK.

Easy handling

With the Z21 app, operation is particularly easy because the signal types are also stored in the app and can be read out automatically from the decoder. RailCom® makes programming via the main track (POM) a lot easier, even when it is installed.

In addition, the Z21 signal DECODER can be easily configured and updated using the Z21 pro LINK. 

By confirming the programming button, the address of the next switching command can simply be adopted as the new address for the Z21 signal DECODER. 

Easy connection

A separate DC supply can be connected so as not to unnecessarily load the outputs of the central unit or booster. If the wiring is as simple as possible, the rail signal can simply be used as the supply.

The outputs are also protected against overload and short circuits. The signals are connected with a common plus. Each LED is connected to the Z21 signal DECODER with its own series resistor, because the output voltage corresponds to the supply voltage.
