For digital control of:

• Illuminations and motors.
• For consumers up to 2 Ampere each output.
• High-current turnout drives with end-switch: e.g. Märklin gauge 1 turnout and signal drives (without stressing the digital circuit).

The voltage will be supplied to the decoder by a separate input from an alternating voltage output of a model railway transformer (12 to 18Volt ~) or from an insulated power supply unit within a range of 15 to 24 Volt =.
Simple and secure connection of the voltage supply and the consumers by screw clips.

• The decoder address can be set by pushing the SA-DEC-4 programming key and the key of the turnout control board or by a switch command of your PC with connected INTERFACE.
• The decoder address will be permanently stored but can always be changed by pressing the programming key again. It’s as simple as that !
