The CIRCUITRON FL-2 is designed to be controlled by the output from one of our Grade Crossing Detection circuits. The FL-2 may also be easily wired for continuous flashing or for m anual control with a panel switch, if desired. Only one FL-2 is needed per road crossing regardless of the number of tracks (each with their own Detection circuit) at the crossing. The FL-2 will power incandescent lamps or Light Emitting Diodes (with proper current limiting resistors). The maximum load that may be applied to each output is 250ma. This is sufficient to flash 3 or 4 standard grain of wheat lamps or 10 - 15 LEDs per side. The current draw of grain of wheat lamps varies widely from one manufacturer to the next. Typically, they will be in the 50-75ma per bulb range. If you are not sure, check them with an ammeter. The outputs of the FL-2 are not protected against over-current or short circuit conditions, and connecting too many lamps to the outputs will likely damage the circuit. This is not covered by warranty. The FL-2 is constructed on a 1.5" x 3" printed circuit board. Show more
