The WFD-27 along with a phone or tablet is a complete 5A Wi-Fi DCC solution!
You can install this Wi-Fi/DCC Command Station/Booster on your layout to provide bipolar DCC encoded power to your track or layout accessories. You can control trains from your tablet or smart phone running one of the WiThrottle Apps such as Engine Driver for Android, WiThrottle for Apple or the TCS UWT-100. Commands will be passed on to a set of locomotives or accessories equipped with DCC decoders. Each locomotive will be addressed separately and be under independent control. The WFD-27 module may receive commands from more than one tablet, addressing the same or different locomotives. A roster of up to 16 locomotives with Function Labeling, or 32 accessories can be stored in the WFD-27 so that you can select the locomotive you want to drive from the WiThrottle app.

The WFD-27 also supports a programming track so that you can read and write DCC configuration variables in DCC Service Mode. You can program operational mode configuration variables on the main track.

WFD-27 5A Wi-Fi/DCC Trackside Command Station/Booster

This module is a complete Wi-Fi/DCC Command Station/Booster and can be easily installed on any scale model railroad to provide Wi-Fi control of DCC Locomotives and Accessories. It is compatible with NMRA compliant decoders.

For example you might have a collection of locomotives HO or N scale that you have bought with DCC decoders already installed or you might have installed some yourself. You can mount this module on your layout and connect its Track output to your track and/or accessory DCC controllers. You can then enter all your locomotives (up to 16) into the roster contained within the module. The WFD-27 module will behave as a DCC command/station booster compatible with any NMRA decoder.

You can drive your trains from your tablet or smart phone running one of the WiThrottle Apps such as Engine Driver for Android, WiThrottle for Apple or the TCS UWT-100.

You can enter up to 16 locomotives in the roster with function labeling, then select a loco from the roster to drive. Alternatively you can just enter a DCC address of an unrostered loco.

Up to 32 named accessories may be entered and selected via the phone app or you can simply enter the accessory address.

The WFD-27 operates either in direct mode or home-net mode. Up to four throttles may be connected in direct mode and up to six in home-net mode. In home-net mode you can leave your phone connected to your home Wi-Fi network while you operate trains.

Main Track and Program Track outputs are provided. Connect the Track outputs to your main track and the Program output to your DCC programming track. On the programming track you can program and read DCC Configuration variables including the DCC Address in DCC service Mode. On the Main Track you can program DCC Configuration variables in operational mode but not read them.

Two screw terminal connections for DC power input, (acts as power output when barrel connector used).
Barrel connector for alternative 15V DC Mains Adapter (Sold Separately).

LED Indicators

Red LED indicates that power is present at the unit.
Green LED flashes when a hand-held device communicates via Wi-Fi. Blue LED indicates DCC supplied on main track. Blue LED flashes when overload shutdown occurs.

Mains Adapter Details

The power adapter must supply between 12 and 18 Volts DC (15V recommended) with a Barrel Plug (2.5mm I.D. x 5.5mm O.D. x 9.5mm). The center pin must be positive.
