Circuitron DF-1 Grade Crossing Detector & Flasher ~ 5250

The CIRCUITRON DF-1 is an advanced, integrated circuit detection unit
with an alternating flasher contained on the same circuit board. The detection part of the circuit utilizes
CIRCUITRON’s proven Opto-Electronic system and provides true-prototype grade crossing for all single
direction applications. If your application requires Bi-directional detection, use a CIRCUITRON DT-1 or DT2 instead. The DF-1 is entirely independent of the track power and may be used for all scales and
methods of power including AC track power and carrrier control systems. The flasher section of the DF-1
will power two 250 ma. loads and may be used with either LEDs or incandescent lamps. Additional
CIRCUITRON detection units may be easily connected to the DF-1 to control the flasher section in order
to provide detection on parallel tracks. An output terminal on the DF-1 may be connected to additional
accessories such as the CIRCUITRON ER-1 or ER-2 External Relays or the BR-1 and BR-2 Bell Ringer
Circuits. The DF-1 may be powered by any 10-18 volt AC or DC source.
