WDMI-24 Wi-Fi/DCC Locomotive Interface Module for Large Scale

This module can be installed within many large-scale model locomotives to provide Wi-Fi control of a DCC Decoder installed in the locomotive. It is compatible with NMRA compliant decoders.

You can then drive the locomotive using our Loco Operator app (Version 3+) or you can use one of our DCCIP Send modules with your existing DCC command station.

The unit is intended for installation in battery powered locomotives with 10-18 Volt batteries.

Functions such as lighting and sound are all controllable from Loco Operator via Wi-Fi.

The WDMI-24 provides programming capability via Wi-Fi in service or operational mode. Locomotives installed with this unit do not need to be placed on a programming track.
