Due to the wide variety of modeling scales, LEDs for use with these products are sold separately and can be found by clicking on the Lighting Products link at the left side of this page. NEW LOW-VOLTAGE SIMULATORS SEE DETAILS BELOW
Miniature Simulator Modules
Smaller than a decoder at just .31" x .31" and utilizing
the industry’s smallest microcontroller and associated
circuitry, these modules consume less than 500 µa (<1/2 ma).
Typical peak operating current with LED(s) attached and running through full brightness curves range
from 18-38 ma. This makes them ideally suited for operation when powered
directly by a function output of any of today's HO, N or Z-scale DCC
decoders. Input voltage range 6-18 volts DC, so they'll work with nearly
every layout environment. On-board current limiting resistor and input wires included.
Early-era Flasher Simulator
This simulator replicates the older-style signal and hazard warning flashers that used incandescent (filament) lamps to generate light. Typical flash rate of 3/4 second with a increasing and decreasing brightness curve to duplicate that of filament type lamps. Three outputs will each drive up to one pair (wired in series) of red and/or yellow LEDs Outputs flash sequentially so the module could also drive a very short series of "chase" lights.
Two new LOW-VOLTAGE
Simulator families
have been introduced: The NLA803X series for analog (DC) operation,
and the NLD803X
for DCC Sound decoders with 3.3-volt accessory
functions and RC applications that use 3.7-3.8 volt batteries. These
low-voltage versions have a wide effective input voltage range of
3.2 to 16 (maximum) volts DC.
This simulator provides a single
repeating burst, increasing and decreasing in intensity to accurately
represent roof beacons like those made by Prime and Federal used by most
railroads. The N8032 supports either yellow or red 20ma LEDs. The N8032A
is for white or blue LEDs,
and the N8032B has 2 selectable speeds.
Cascadable Chase Light Simulator This simulator will sequence 6 white or yellow-white LEDs in succession (1 through 6) then repeat over and over when input control is grounded (-DC). Unlike the chase light Simulator above, this version can be cascaded together for a virtually unlimited chase sequence. Click on Connecting in More Info (to the right) for details of wiring and operation. The N8049D version is for red, orange, and/or yellow LEDs.
Arc & Gas Welding Simulators Finally, welding simulation that looks just like the real thing! A bit of shameless back-patting, but we believe it is warranted. These simulators are configured for connection of two LEDs to accurately reproduce the varying intensity, intermittence and slight color changes just like real welders. Our Nano LEDs are perfect for reproducing these effects. N8064 is the arc welder and N8064B is the gas welder. See Connecting under More Info to the right, for product details.
Tower Beacon/Strobe Simulator The N8071 is configured to generate either a beacon effect (ramping up & down of brightness - the default setting), or a strobe effect for the primary (top of tower) red LED. Additionally, up to 4 more red or yellow LEDs can be connected which will run in a continuously-on state. This configuration allows this module to simulate the lighting of many different radio, cell and TV towers. The N8071B is configured for a primary (top of tower) white LED. This is typical for towers with a strobe light at top position.
6-LED Police Strobe-bar Simulator
How often have we seen a roof-mounted strobe-bar on a police vehicle from a mile or more away? Very eye-catching to say the least This circuit will sequence 6 LEDs in rapid strobe-like fashion, simulating the effects of typical police vehicle roof-mounted strobe bars. The configuration is quite dazzling in appearance and is intended for two white, two blue and two red (or yellow) LEDs. The N8072A is for two blue, two yellow & two red LEDs.
Rotating Beacon Simulators
These modules reproduce a highly realistic simulation of rotating beacons by sequencing LEDs (sold separately) that are positioned to produce the effect. See the More Info table to the right for complete information. The N8042 is for a red or yellow 3-LED assembly. The timing of the rotational effect closely replicates that of rotating beacons seen on various aircraft including helicopters. The N8042A is the white-LED version. The N8042C is for a red or yellow 4-LED assembly that simulates the "gumball" type of rotating beacon.
Universal Strobe Simulator
This simulator will support strobe effects for a wide range of aircraft. The strobe pulse is a short 70ms burst occurring either once per second on all three outputs simultaneously, or when the simulator input is grounded, on two outputs together and one output separately, alternating at one-half second intervals . See Examples of use in the More Info table to the right for complete information.
Machine Gun Simulator (modern)
This simulator generates a rapid stream of pulses alternating between 2 connected LEDs whenever the input pin is grounded. The timing and duration of these pulses mimics the appearance of automatic weapons fire like that seen in WW2 and modern era wing and belly guns on planes and attack helicopters. The N8060A version of this module is configured for 4 LEDs alternating between pairs to simulate 4 guns firing.
6-LED Chase Light Simulator This simulator will sequence 6 white LEDs in two different ways. With the input control pin left unconnected, LEDs will light in succession (1 through 6) then repeat over and over. This will simulate airport runway chase lights used for traffic landing assistance. With input control grounded (-DC), LEDs will sequence in an up and down fashion (1,2,3,4,5,6,5,4,3,2,1) and repeat over and over. The N8049A version is for red or yellow LEDs.
Furnace / Forge / Sawdust Burner Simulator This module generates a slow, random undulating brightness output for either a single LED, or 2 series-wired LEDs. It closely replicates the exhaust glow of a jet engine being throttled up and down. The use of 2 LEDs gives double the light output. When strategically placed, it can create a reflective effect that can add significant realism to various aircraft. If used with our Nano LEDs, even the smallest scale model can benefit form the effect.

Navigation Light Simulators
These modules generate various different effects to simulate aircraft navigation and running lights including strobes and beacons. Details of each Simulator's effects and instructions for connection are covered in the More info table to the right. Just click on each item Details for information.
