WFS-87 Eight Way Wi-Fi Universal Switch Machine Controller
WFS-87 8-Way Universal Wi-Fi Switch Machine Controller
Available Now!
This Wi-Fi Switch Machine Controller provides Wi-Fi or DCC Control of eight switch machines of any type. This product is useful when you have a group of up to eight switches fairly close together. If you have more than eight switches in close proximity you can use a second 8-way or 4-way switch machine controller.
Control your switch machines (point motors) either with the in-built web pages, using your DCC Command Station or, with the WFD-60, or from a WiThrottle Protocol app on your phone such as Android Engine Driver, Apple WiThrottle or the TCS-UWT-100. You can also use our free Tower Operator App to control four of your model railroad switches by tapping a switch symbol on the custom layout map you build on your Windows 10 or Android computer or tablet.
This Wi-Fi Switch Machine Controller provides Wi-Fi or DCC Control of eight switch machines. The switch machines can be twin-coil, bipolar, stall motor, or end-switched motor. This product is useful when you have a group of up to eight switches fairly close together.

WFS-87 8-Way Wi-Fi/DCC Universal Switch Machine Controller
This module is an upgrade from our WFS-86 to include DCC operation and various other improvements such as LEDs to show status and operation from any browser using internally generated web pages.. You can install this module on your model railroad of any scale to operate four switch machines using control from the in-built web pages, your own DCC command station or our free Tower Operator App that runs on Windows 10 and Android. You can also use this module withthe WFD-60 WiThrottle Protocol Gateway to control switches with Apple WiThrottle or Android Engine Driver on your phone; or the TCS UWT-100.
This switch machine can operate various types of switch machines. These include:
- 3-Wire Dual-coil switch machines such as those manufactured by Peco and Atlas,
- 2-Wire Bipolar switch machines such as those manufactured by LGB or Kato,
- Stall-motor machines such as Tortoise by Circuitron,
- Other motor driven switch machines with an end switch - up to half an amp.
In-built charge pump, capacitor discharge unit doubles track voltage for dual coil switch machines
Fully compatible with DCC systems. Can use power from DCC Booster or fixed DC on track, or separate DC supply.
Input connections allow manual operation from buttons or track occupancy detector.
