Circuitron FL-2 Alternating Flasher

to be controlled by the output

from one of our Grade Crossing

also be easily wired for continuous

flashing or for manual control with

a panel switch, if desired. Only

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 250 ma. 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 50-75 ma. per bulb range. If you are

not sure, check them with an ammeter. The

over-current or short circuit conditions, and

connecting too many lamps to the outputs will

likely damage the circuit. This is not covered
