Accessory Decoders

These stationary decoders allow you to switch points, signals and lights using DCC accessory addresses.

Please note that the Lenz system uses addresses as specified by the NMRA Recommended practices.

On the Lenz system, locomotive addresses, accessory addresses and feedback addresses can all be used together with no conflicts so you can have loco number 1, point number 1 and feedback number 1 on the same layout without there being a problem.

Lenz 11101 LS101 Accessory decoder for 4 turnouts with feedback 
New 2023

Components used to manufacture the LS100 have become difficult to source so the LS101 has been designed to use new technology to provide the same function as the older LS100

Accessory decoders are the link between your NMRA DCC system and your functional devices (that is turnouts, signals, uncouplers, etc.) on your model train layout.
Accessory decoders receive commands sent from the command station via the power station and activate the drives of turnouts or other switching devices. For DIGITAL plus systems these switching commands are activated from input devices, such as, hand held controller LH101, LH100 or LH90 (or in connection with another, compatible digital system).
Dimensions: approximately 3.5 x 3.5” (90 x 90 mm)

Lenz 26160 additional Power Supply for LW150 module.  Now Available

On a large system that uses a number of XpressNet devices you may find that you need additional power.  The LW150 has a socket that allows you to feed additional power into XpressNet using a 26160 transformer.

The LZV100 provides 300mA to XpressNet. Below is a table of XpressNet devices and the power that they use:


Item Connection Power requirement
LH100 Handset XpressNet (LMAB) 28mA
LH90 Handset XpressNet (LMAB) 18mA
LH01 Handset XpressNet (LMAB) 30mA
USB Interface XpressNet (LMAB) 21mA
LW150 without LEDs XpressNet (LMAB) 18mA
LW150 with LEDs XpressNet (LMAB) 39mA
LS100 Feedback connection RS 1.5mA
LR101 Feeback module RS 1.5mA
