The FL-2 may also be easily wired for continuous flashing or for manual 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 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 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.","brand":"Circuitron Electronics","offers":[{"title":"Default Title","offer_id":46404164911335,"sku":"TOR5102IH","price":18.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/7798\/9095\/products\/800-5102-fl-2-alternating-flasher-mpm-hobbies.jpg?v=1750785618"},{"product_id":"800-5122-fl-2hd-heavy-duty-alternating-flasher","title":"800-5122 FL-2HD Heavy Duty Alternating Flasher","description":"The FL-2HD is identical to the standard FL-2 with the exception of the output load capacity.

The three outputs on the SD-1 can each control a maximum of 250 ma. and they will power either LED or incandescent lamp type signals. If your signals use LEDs, make certain that they are connected with a\u003cbr\u003ecommon positive (anode) connection of all LEDs (the signal should have 4 wires, and the “common” connection should go to [+]. Most, but not all, signal manufacturers follow this design.  Detection circuits (such as the CIRCUITRON BD-1, BD-2 or BD-3) that provide a logic low (- or ground) output are needed for a minimum of 2 blocks to display all three aspects.

(Note: The flash rate of prototype Ditch Lights varies widely depending on the railroad.  The flash rate of the DL-1 is easily changed by replacing the one timing resistor on the circuit board. If room permits, a small adjustable trimmer can be wired in place of\u003cbr\u003ethe fixed resistor to allow a wide range of adjustment of the rate. Send an SSAE and\u003cbr\u003erequest Application Note AN1400-01 for more details.) With the addition of an optional DPST or DPDT switch (see ACCESSORIES), the DL-1 can be easily bypassed to turn the ditch lights constantly on. The DL-1 circuit board measures 0.6” x 0.4” x 1.1” and requires a 2.4 - 3.0-volt DC input which can be supplied by batteries or the CIRCUITRON TP-2 or TP-3 Track Power Adapters.","brand":"Circuitron Electronics","offers":[{"title":"Default Title","offer_id":46689166229735,"sku":"TOR1400IH","price":17.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/7798\/9095\/files\/800-1400-dl-1-oscillating-ditch-lights-mpm-hobbies-1.jpg?v=1750785844"},{"product_id":"800-5530-sd-3-signal-driver-3-aspect-bi-color-led","title":"800-5530 SD-3 Signal Driver, 3 Aspect, Bi-Color LED","description":"The CIRCUITRON SD-3 is capable of driving any single searchlight style, 2 lead or 3 lead, Bi-Color or Tricolor, LED type signal to red, green and amber aspects. Compatible signals are manufactured by Oregon Rail Supply, Tomar, Sunrise Enterprises, ISS and others. Two SD-3s are required for double-head signals. NOTE: The SD-3 will not drive 3 lamp signals (see SD-1). Bi-color LEDs contain both a RED and a GREEN chip mounted side by side. Amber is achieved by alternately lighting the red and green LED chips at a high frequency. The eye perceives this mix of red and green as yellow (amber). A hue adjustment is provided on the SD-3 to allow adjusting the amber color. The SD-3 may be controlled by a single-pole, 3 position switch or automatically by detection circuits such as the CIRCUITRON BD-1, BD-2 or BD-3 (minimum of 2 blocks required). Other detection circuits that provide a logic low (ground or -) output may also be used.
