The Z21 Switch Decoder is a universally usable DCC switch decoder with a 2 Amp output power for up to 8 switches or up to 16 consumers such as LEDs and light bulbs. Easy connection: To avoid unnecessarily overloading the outputs of the central unit or booster, a separate DC power supply can be connected. If a simple wiring solution is desired, the track signal can also be used as a power supply. The outputs are also protected against overload and short circuits.

Adjustable outputs: Each of the 8 output pairs can be set independently to different modes. These are preconfigured and can be easily selected. Each output pair can also be dimmed individually to precisely adjust lighting.

Ideal for:

• Adjustable modes
• Double-coil drives
• Simple light signals
• Lighting
• Controlling relays

Standard operation – With configurable activation duration for double-coil drives.
Momentary operation – Switches for turnouts and uncouplers depending on the activation duration at the handheld controller.
Bistable continuous operation – Switching on or toggling for lighting and signals.
Bistable continuous operation – Switching on or toggling with bulb simulation.
Flashing light – Flashing light with bulb simulation.
Switch numbers 1–2040.
