lenz DCC

Lenz is arguably the best known name in the world for Digital Command Control having had the original format devised by Bernard Lenz adopted by the NMRA which has evolved into the DCC standard now universally accepted.  Lenz now produce two DCC system variations which differ only in the style of cab they use.  The Compact, which was their entry level starter system, is no longer manufactured.


Both the Lenz Start Sets are based on the LZV100 Command/Power Station and differ only in their handheld.  The LH100 Cab for the Set 100 and the LH90 cab for the new set 01.

LZV100 Specification:

  • Command Station using the Lenz XPressNET protocol.LZV100
  • Power Station capable of 5 Amps continuous
  • Connections for:

        Main Track.
        Programme Track.
        XpressNET Din Socket.
        XpressNet Terminals for additional sockets.
        RX Feedback Bus.
        Command Station Bus for additional boosters.

LH100The LH100 cab and LH010 have identical capabilities but different input method.  Speed is the most obvious with a large Knob for the LH010 and buttons for the LH100 and on the on screen displays show different levels of information.

Short addresses up to 99; long addresses to 9999.

Can run one analogue loco on address 0.

1024 accessory addresses.

LH9029 Function; F0 to F28

    Simple and Advanced consisting.

    All programming modes including POM.

    RS Feedback bus for 2 way communication.

    Up to 31 input devices (cabs).

    Both these cabs give access to the full spectrum of DCC functionality.

Both of the controllers are available separately for use as additional cabs.


Each LV102 gives a further 5 Amps of power which can be applied to separate power districts within your layout or it can be used in Tandem with the LZV100 to provide a 10 Amp system,

Combining 2 LV102s in Tandem produces a 10 Amp booster.  Each LV102 requires its own 5 Amp transformer

LA152LA152 XpressNet adaptors allow the use of additional cabs at different parts of a layout.  Multiples LA152s can be daisy chained around the layout.

Cabs cab be unplugged and moved between adaptors without interrupting layout activity.


Mobile Decoders.    Lenz offer 3 loco decoder variations:

- The Lenz basic loco drive decoder for OO/HO without any of the additional Lenz  functionality.   

  • BEMF
  • Silent Drive.
  • 1 Amp continuous, 1.8 Amp max.
  • 3 function outputs at a maximum of 300mA each or in total, sort circuit protected.
  • 14, 27, 28 or 128 speed steps.
  • Long and short addresses
  • Low speed setting for shunting.
  • Advanced consisting.

- All the attributes of the Standard decoder plus support for asymmetrical DCC including directional stopping.

Gold - All the attributes of the Silver decoder plus:    

  • NMRA bidirectional data communication (BiDi) support.
  • Contacts for USP modules.  Uninterruptable Signal Processing to overcome connectivity problems.
  • SUSI sound interface.

accessory decoders

Lenz offer 2 accessory decoders:

LS100The Lenz LS100 is a 4 output accessory decoder for twin solenoid point motors
User changeable pulse duration or continuous on.

Position reporting to the LZV100 via XpressNet.

Can be used for slow motion (stall) motors by the addition of LA010 output modules.

The Lenz LS150 is a more cost effective accessory decoder designed for twin coil turnout motors but can be adapted with LA010 modules to run stall motor types such as the Tortoise.

It ha a maximum rating of 3 Amps and requires an external power supply which must not exceed 3 Amps.

Asymmetric DCC Braking Control

Lenz offer a series of modules which use the application of an asymmetric track current to isolated track sections (blocks) to initiate braking and stopping actions automatically.  They can be used with any locomotive decoder that supports Lenz ABC and do not require the use of a Lenz DCC system.

BM1 - The simplest stop module for a red signal or to protect a point.

BM2 - More sophisticated braking control for a single block.

BM3 - Used to control a series of blocks by braking if the block in front is occupied. 

Other Accessory Modules

The LR101 is a 4 input feedback module that uses XpressNet to communicate with the LZV100.  It can accept input from several different devices including the LB050 Voltage Detector for a single block and the LB100 dual occupancy detector.

The LG100 is an Automatic Stop Generator that can be used with any system or decoder.

The LK200 is an  Auto Reversing Module.

The LT100 is an Analogue Protection Module where DC and DCC layouts meet.

The LRC120 Local Railcom Detector allows you to read out locomotive addresses and CVs anywhere on the layout, moving or stationary, providing it is the only loco in the block that the LRC100 is connected to.  It requires the loco either to have a Railcom enabled decoder on board, e.g.Lenz Gold, or to be fitted with a separate LRC100 module programmed to the decoder address.  The Lenz Railcom protocol is currently being adopted as the NMRA DCC standard for bi-directional communication but, as yet , few other manufacturers support it.
