QuadLN_S Signal Board

$19.95 SALE $13.97 30% OFF

The QuadLN_S Signal Board add-on provides 24 LED outputs and realistic effects for Searchlights, CPL signals and crossings. Includes mounting screws and standoffs.

QuadLN_S Signal Board Features

  • Plugs in the QuadLN_S Exp IO Port.
  • Provides 24 LED outputs.
  • Any mix of common cathode, common anode and 2-lead bicolor LEDs.
  • Standard 3 pin headers with Output, 5V and Ground for easy wiring with servo extension cables.
  • Searchlight transition effects.
  • CPL semaphore effect.
  • Realistic fade.
  • Flashing aspects are handled locally by the QuadLN_S with proper flash rates, eliminating Loconet traffic jams when trying to have JMRI constantly flash signals.
  • Proper Grade crossing flash rate along with cross fade that makes your crossing look like the prototype back when bulbs were used.
  • Software brightness adjustment for each LED output.
  • Built-in 330 ohm resistor in each LED output eliminates the need for external resistors in many cases.
  • On-board mounting points to add your own resistors when a lower resistance value is required.
  • Up to 48 signal aspects can be defined to provide prototypical signaling.
  • Each aspect can control up to 4 LEDs.
  • Aspect control is very flexible and each aspect can be configured for control by Signal Mast messages, Turnout messages or Sensor messages.
  • Signal wiring breakout board available with screw terminals or solder pads.
  • The QuadLN_S Signals Manual has all the details! (download below)

Signal Board In Action

The QuadLN_S Signal Board animating a Searchlight signal on Duncan McRee’s Tam Valley layout. Notice the trademark “Red Flash” and “wobble” searchlight mechanism effects. Looks even better in person, but if you love searchlight signals like I do you get the idea. Video courtesy of Duncan McRee.
Searchlight Signal effects on my D&RGW N scale layout. The benchwork- mounted circuit board signals are stand-ins until I get real n-scale signals installed on the layout (someday). Details on the signals are available over on the projects page on my layout site: n-scale-searchlight-signals
Signal Board directly driving an Atlas 094 Modern Signal HO mast. No external resistors are required. The brightness of each LED can be individually adjusted using sliders on the QuadLN_S decoder LED tab or with the Remote Align Board.
