The Z21 switch Decoder is a universally usable DCC switch decoder with 2 ampere output power for up to 8 points or up to 16 consumers like LEDs and incandescent lamps.Simple connectionTo avoid unnecessary load on the outputs of the central unit or booster, a separate DC supply can be connected. If wiring is as simple as possible, the track signal can also be used as a supply. For this purpose, the outputs are also protected against overload and short-circuit.Adjustable outputsEach of the 8 output pairs can be set independantly to different modes. These are already pre-configured and can be easily selected. Each output pair can also be dimmed individually, in order to be able to adjust lighting exactly.Ideal for:Adjustable modesDouble coil drivesSimple light signalsLightingControlling relaysStandard operationwith configurable duty cycle for double coil drivesMomentary operationswitch on the manual controller for points and uncouplers depending on the duration of actuation (like 10
