Four channel wireless controller for operation of model railroad accessories

Four channel wireless controller for operation of model railroad accessories

This is a handy wireless control module for independent control of up to 4 channels. The self contained module is powered from 12 volts DC. A 4 channel controller FOB permits independent control of up to 4 different circuits. A jumper can be set to permit ON OFF control using 1 button.

This controller is now used to operate LEDs installed on a custom built O scale construction equipment service building. (photo shown)

Circuit 1 controls exterior lighting for service bay 1.

Circuit 2 controls exterior lighting for service bay 2.

Circuit 3 controls all interior lighting.

Circuit 4 controls front and rear exterior lighting.

Pretty cool. I take it the two terminals on the right are power inputs?

Where and how much and what's the P/N?

Tons of these on eBay in all kinds of flavors. Search for 4 channel rf remote relay and you'll get lots of hits. You can get various combinations of channels, individual relay boards for each channel, etc.

Here's one for $11 shipped: 131559897274

The control circuit requires 12 VDC and is applied at the terminals marked + and -. Since my LEDs only require about 5 volts each a separate voltage regulator circuit is used for lighting. The regulator circuit is also powered by the 12 VDC. A circuit diagram is also attached. Note: The LEDs shown have a series limiting resistor included.
