  • DCC decoder DCX77z

A micro dcc decoder suitable for N and Z gauge.


Current Rating - Avg 0.8 Amps , Peak 1.2 Amps

Connector - Wires

The locomotive decoder DCX77z suitable for all DC and AC motors in Z gauge up N locomotives. The maximum total load must not exceed 0, 8A.  The DCX77z offers high-frequency 16 kHz or 32 kHz motor control for Faulhaber motors. Alternatively, there are also infinitely variable 30-150 Hz for traditional engines available.

The DCX77z offers either with 14, 28 or 128 speed steps, load compensation scheme, full address space from 1 to 10240 and the possibility of the main track on-the-fly' program.

  • Full NMRA compatible (DCC data format)
  • DCC data format
  • Full 'function mapping" according to NMRA arrangement
  • Function outputs separately dimmable
  • Dimming frequency 1.2 kHz
  • Automatic disconnection, time control for digital clutch,
  • American light effects, such as flashing, fading, blinking in the push-pull, single pulse strobe, double strobe, flashing headlight, ditch light left ditch light right Rotary beacon, Gyralite, Mars light, soft-start (slow ignition up of functions)
  • Full address space 1-10240
  • Shunting function, display cases mode a button switching function, reduced backwards speed...
  • Evaluation of chain pulses via F1 or F4
  • Free speed curve CV67 to CV94
  • Optimizable load balancing (P and I control)
  • High-frequency motor control 16 kHz or 32 kHz
  • Low-frequency motor control by 30 bis150 Hz selectable
  • Optional 14, 28 or 128 speed steps
  • 0.8 Amp motor current
  • Digital or analogue operation
  • 'on the fly' program
  • Hard reset to reset the CV values to factory setting
  • User CV's to the stored personal data
  • Separately adjustable braking time with HLU (also, intermediate)
  • Signal-based train control (HLU Zimo, off)
  • Train number recognition (Zimo, off)
  • Brake with an asymmetrical signal (diode ratio 1:4)
  • Fully programmable with train mouse controls (also values and CVs to 255)
  • Reliable overload protection motor, auxiliary outputs are not protected against overcurrent
  • 2 CVs group freely selectable (for own or third-party applications)


The DCX77z is full NMRA compatible and thus all systems that use the NMRA DCC data format can be used (E.g., Digitrax, Lenz, LGB, Uhlenbrock, Zimo, Roco ' digital is cool', etc.)
