Description: EVERY ORDER now gets a $5.00 coupon code toward a future order!Mountain Subdivision HobbiesmodelrrsupplyCircuitron #5102 FL-2 Alternating Flasher Circuit for Grade Crossing SignalsThe CIRCUITRON FL-2 is a complete solid state flasher that will alternately flash two 250 ma. loads. The FL-2 contains on-board regulation to allow the unit to be powered by 10 - 18 volts AC or DC, and has a control terminal for use with CIRCUITRON detection circuits. Mounting pads are provided on all four corners.The CIRCUITRON FL-2 utilizes a low-power CMOS integrated circuit connected as a free-running astable multivibrator. A diode in conjunction with a zener and a filter capacitor provide a source of filtered DC for the IC. The complementary outputs from the integrated circuit drive two transistors (Q1 & Q2). A ground connection on the control terminal (C) enables output from the IC to the transistors. Returns from the loads are alternately grounded by Q1 and Q2 connected common emitter.INSTRUCTIONS: The FL-2 can be connected with .110" x .032” solderless connectors (available from CIRCUITRON) or by soldering leads directly to the terminals on the printed circuit board. If soldering, use a small pencil-type iron and electronics-grade rosin core 60/40 solder (available from Radio Shack). Use only as much heat as necessary to obtain a good joint and do not wiggle the terminal until the solder has cooled completely. A section of CIRCUITRON’S PCMT can be used for simple, snap-in mounting of the circuit board or you may drill holes in the mounting pads in the corners of the board and mount the FL-2 / FL-2HD with screws and standoffs.1) Connect a wire from the terminal labeled [OUT] to one side of all the lamps or LEDs to be flashed. Note: If LEDs are to be used, a proper value limiting resistor must be included in this connection. In addition, the proper polarity of the LEDs must be observed. (See Table 1 and the instructions packed with the LEDs or signals.)2) Connect the remaining leads of the left lamps together and run a wire to the terminal labeled [L].3) Connect the remaining leads of the right lamps together and run a wire to the terminal labeled [R]. NOTE: If you are using LEDs, the return leads [R & L] must be connected to the terminal on the4)Connect a wire to the control terminal [C] and run it to the output of a detection circuit such as the CIRCUITRON DT Series that provides a grounded output when a train is detected. For instructions on connecting the CIRCUITRON FL-2 / FL-2HD to detection circuits that provide a logic high (positive voltage) output, consult the factory. For manual operation, connect a switch between the [C] terminal and the [-] terminal. For continuous flashing, connect a jumper between the [C] terminal and the [-] terminal. 5)Connect a 10 - 18 volt source, either AC or DC to the terminals labeled [-] and [+]. If DC is used, observe proper polarity.LEDs denoted by a flat spot or notch in the plastic. This is the cathode ( - ) terminal.Connect a wire to the control terminal [C] and run it to the output of a detection circuit such as the CIRCUITRON DT Series that provides a grounded output when a train is detected.

If DC is used, observe proper polarity.CAUTION:Make certain that the total load applied to the left or right return terminals [L] and [R] does not exceed 250 ma. each (500 ma. for the FL-2HD). Exceeding the rated specifications of the FL-2 will result in overheating of the output transistors and probable failure of the device(s). This constitutes abuse and is not covered by warranty.__________________________________________________________________Questions, Special orders, Inventory requests:Please contact us using eBay's message system.
