Specifically deigned for use at grade crossings, using Opto-Sensors to detect the train. Output controls flasher, gates, bells, etc. Detects train when an Opto-Sensor is covered. Senses track polarity and activates only the Opto-Sensors for the direction of travel. Always turns off after the last piece of rolling stock clears the crossing. Includes four Opto-Sensors. Requires an Alternating Flasher Unit to operate flashing lamps. Note; DT-1 cannot detect a short train or

Specifically deigned for use at grade crossings, using Opto-Sensors to detect the train. Output controls flasher, gates, bells, etc. Full logic system duplicates prototype grade crossing action. Does nt require sensor stay covered to activate. Integrated memory keeps output ''on'' until last car clears the crossing. Activates whenever a train approaches from either direction, If trains stop short then backs away, until will detect that and turn output ''off.'' Independent

A self-contained AC to DC converter with an adjustable voltage can be adjusted anywhere between 1.25 and 12.00 volts DC. Maximum continuous current output of the PS-2A is in excess of one amp. Ideal for powering any low current DC accessories including 1.5V micro-lamps. The AC or unfiltered DC input should be about 5-6V higher than the desired regulated aouput. The input voltage to allow maximum current output. The input voltage may be as high as 22V, but this may result in

Tiny Opto-Sensors detect train movement. Sensors mount between the rails and activate circuitry when shaded from a passing train. Independent of track power, rolling stock requires no modifications. Sensors fit between ties and may be ballasted over in most cases. Circuitry is extremely sensitive and will operate properly under very low levels of room light. Positive indication whenever a section of a layout is occupied by rolling stock. Contains all circuitry to power
