Connecting the Dual Roto-Ray Simulator for red LEDs

The N8089 simulates the effect of two rotating Roto-Ray warning lights by sequencing 6 LEDs connected to its output (pins 3 - 6) when power is applied to the inputs (pins 1 &2). This module is not designed for use with incandescent (filament) type lamps or bulbs.

Installing the N8089module is very straightforward. Because the module has circuitry on both sides, care must be taken to be sure that the components or wires soldered will not make contact with any metal object which could cause a short circuit.

Any well regulated DC power source can be used to power this module providing the voltage is at least 6VDC and doesn't exceed 18VDC. Our N3512B and N3518 Power supplies are ideal for this use. Also, due to the very low power consumption, this device can also be powered by a battery, such as a standard 9-volt.

Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires, decoder or module and void the warranty.

Also, all connecting wires should be pre-tinned before soldering them to the module. This will make connection quick and easy and ensure excessive heat is not applied to the solder points.

Connecting LEDs

Included with the module are two 6” lengths of #32 insulated wire. If necessary, these can be used for power input wires. The red wire should be soldered to solder point ! (+DC input) and the black wire to solder point 2 (–DC input).

When connecting the LEDs, proper polarity must be observed. LEDs are “polarity sensitive” and will not function is connected backwards. The N8089 is configured to connect 3 series-wired pairs of 20 ma LEDs with device voltages of 2.0 VDC. This covers all of Ngineering’s Micro and Nano red LEDs, as well as many other red LEDs available.

Figure 2 below shows a schematic layout of wiring connections

Once again, be sure to use a low-wattage soldering iron when connecting wires to the module.

LEDs are noted with "A" = Anode and "C" = Cathode

This completes connection of the N8089module. It is recommended that a thorough re-inspection of all connections and module placement be performed prior to applying power. We hope you enjoy the added realism our module provides.
