Miniature Simulator Modules
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
Two new LOW-VOLTAGE
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.
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.
This simulator provides a single repeating burst, increasing and decreasing in intensity for a single yellow 20ma LED. While designed to mimic a typical roof warning beacon, it also simulates the effect of most early-era bulb-type roadside warning flashers (detour, road work, pedestrian crossing, hospital zone, etc.).
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 & Modern-era Alternating Flasher Simulators
The 8038 series modules reproduce alternating flashes (with increasing and decreasing brightness curves) as seen in the older incandescent lamp driven type crossbucks used at grade crossings. The 8041 series simulate modern-era LED driven devices. All will drive up to two pairs of series-wired red LEDs without additional external circuitry. The N8041A will drive up to three pairs of series wired LEDs which alternate sequentially.
Rotating Beacon Simulators
This module is designed to reproduce a highly realistic simulation of a rotating beacon by sequencing 3 yellow LEDs (sold separately) that are positioned to produce the effect. See LED Construction in the More Info table to the right for complete information. The timing of the rotational effect replicates that of rotating beacons used occasionally on street or highway signs to draw attention.
Custom Lighting Effect Simulators
Do you need a special lighting effect that that no one produces or have a unique prototype requirement? We may be able to help. The N8050 will support 1 LED output, the N8051, 2 LED outputs, and the N8052 will support 3 LED outputs. For an additional programming charge (quoted separately), we will program the appropriate simulator to create your effect. Just email or call us with your requirements. We will review them, determine if they are within the capabilities of our simulator, and if so, respond with our quotation. Delivery can be within 2 weeks and our quote will be reasonable.
After approval and response to our quotation, add appropriate item(s) to the shopping cart, then enter the agreed-upon programming charge and add it to the shopping cart. Once we receive your order, we will begin processing.
Catenary Spark Simulator
We have all watched electric locomotives, traction vehicles or trolleys as they move along the rails and have seen the sparks created by the pickup as it travels along the overhead (catenary) wires. This visual effect also very closely resembles the sparking seen with shorting power cables such as wires between power poles. The tiny size of our Nano white LEDs are perfect for this application, and if strategically placed will greatly enhance a scene of a roadside repair crew.
Arc & Gas Welder 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.
AUTOMATIC CURRENT PROTECTION!
At just 3/4" square, this product series includes a state-of-the-art current source which provides a constant 20 ma for LEDs connected to the module. This means any color 20 ma LED can be connected without the need for external current limiting resistors, multiple LEDs can be connected in series (requires a power source of sufficient voltage) and different colors of LEDs can be combined in the same series. All will operate at 20 ma.
For certain applications it may be desirable to have the LED (or series string) connected to operate at less than full brightness. For this purpose, solder pads are included on the back of the module for placement of resistors to adjust of current source output.
Input voltage range 6-16 VDC. Extra power wires included.
This module is designed to produce a short "burst" flash of approximately 1/15 of a second (65-70 ms) at a rate of two times per second (2 Hz). This simulates strobe flashers such as those used on modern-era road work signs.
Campfire / Fireplace Simulator
This simulator produces a random varying change in output intensity for either a single LED, or 2 series-wired LEDs. Two LEDs will provide double the light output. The effect realistically mimics the crackling fire of a campfire. Perfect to add a road or trailside scene of a campfire or picnic BBQ. If used with our Nano LEDs even the smallest scale scene can enjoy the realism this effect produces.
Produces a flash of 3/4 of a second (700-750 ms) with a 50% duty cycle (equal on and off periods). This simulates the style of flasher used for various modern-era traffic signals, certain highway/roadway conditions, air traffic clearance for buildings/radio towers, etc.
Defective Sign/Light Simulators
The N8069 is a 3-output simulator that reproduces the effect of a flickering or defective light on its first output channel, with the remaining 2 channels being on continuously. This allows connected LEDs to be strategically placed in model signs to display this effect dramatically. It can also be used in building, streetlights, or railroad passenger cars for the same effect. How about creative placement in a back-lit building sign for a humorous effect.
Fusee (trackside flare) Simulator
The N8070 is designed to simulate the shimmering light of a trackside flare (fusee) for either 2 series-wired LEDs or a single LED. Additionally, at power-on several short bursts of light occur followed by a brief pause to give the appearance of igniting the flares. This ignition sequence only occurs at startup and can be disabled entirely by connecting the input control to –DC.
Produces a flash with a 50% duty cycle (equal on and off times). Rate of flash is adjustable from 30 flashes per second (33 ms) to one flash every 3 seconds. This adjustment is made by rotating the slotted center of a variable resistor (bottom right corner of flasher). This flexibility allows for adaptation to a wide variety of warning and attention lighting.
Simulator Booster Boards
4-way Intersection Traffic Signal Simulator
The N8108-01 is designed to provide centralized connection for LEDs and series wired LED pairs connected to pad pairs which simulate a 4-way traffic intersection with timed lighting effects for green, yellow and red LEDs. This module has its own switching buck regulator circuit that can handle DC input voltages of 7.5 to 20VDC. All connected LEDs are supported by on-board resistors for current protection (and brightness balancing & control), so wiring is very simple.
Utility Vehicle Flasher Simulator
The N8075 is designed to generate lighting effects for either 2 pairs of series-wired LEDs or two individual LEDs. It will simulate the alternating strobe lights seen on many city vehicles. If a single LED is used, it will simulate the strobe beacons seen on many smaller utility vehicles such as a forklift.
The tiny size of our Miniature Simulator modules above make them extremely versatile for all modeling scales. However, this size also limits output driving capability to 25mA at 5-volts DC per output channel. This is sufficient to support a very wide range of lighting effects.
Supports up to 200mA and 18VDC per output channel
However, there are many modeling situations where a particular lighting effect may be desirable if it can be reproduced on many LEDs (series or parallel groups) or LEDs that exceed the 25mA or 5-volts DC. This is where our Booster Boards shine (forgive the pun). At just 0.8" x 1.50", these small boards increase a simulator's output up to times a Simulator's output and a DC voltage range of 9-18 VDC. This greatly expands the versatility of many of our Simulator products, especially where LEDs can be wired in series groups!
The Boosters come in 3 flavors: N8103-1 to support a single output Simulator (i.e., N8032 Beacon), N8103-2 for 2 output Simulators (i.e., N8038 Early-era Alternating Flasher), and N8103-3 for 3-output Simulators (i.e., N8043 Universal Strobe). A Simulator is easily be piggybacked on a Booster Board (connecting wire included) and share a common power input for both..
This module creates an alternating flash between a pair (or pairs) of LEDs of approximately 3/4 of a second and 50% duty cycle. This is a typical sequence for many modern-day traffic warnings such as school zones, traffic revisions, low bridges, etc. This product supports "common anode" devices, see More Info for details.
Variable-rate Alternating FlasherThis module creates an alternating flash between a pair (or pairs) of LEDs with a 50% duty cycle (equal on and off times). Rate of flash is adjustable from 30 flashes per second (33 ms) to one flash every 3 seconds. This adjustment is made by rotating the slotted center of a variable resistor (bottom right corner of flasher). This product supports "common anode" devices, see More Info for details.
