Roco 10836 Z21 Switch decoder

The Z21 switch decoder is a universally applicable DCC switch decoder with an output of 2 A, designed for up to 8 switches or up to 16 elements, such as LEDs and bulbs.
Simple connection:
A separate DC power supply can be connected so that the control center or the booster outputs are not overloaded unnecessarily
If the wiring needs to be as simple as possible, the track signal can also be used as a power supply.
In addition, the outputs are protected against overload and short circuit.
Adjustable outputs:
Each of the 8 output pairs can be set to different states independently of the other. These are already pre-configured and can be simply selected. Each output pair can also be dimmed individually, so that the lighting can be adjusted exactly to your needs
It can be combined with:
Twin coil motors
Simple light signals
All kinds of lighting
Control of relays
Highlights:
8 output pairs can be set independently
Optional power supply via additional power supply
Programmable with RailCom on the main track
