The Circuitron 5400 AR-1 Automatic Reverse Circuit is an automatic train reversing circuit — flips the direction of DC track power whenever the Opto-Sensor is covered (or a pushbut ton is pressed) for point-to-point automation.What it does: Changes track-power direction when the Opto-Sensor (sold separately) is covered by an approaching train. Perfect for test tracks, window displays, point-to-point mine trains, or automatic reverse-loop operation on small DC layouts. Pushbuttons may also be connected for manual reversing. 5 A capacity relay handles big locomotives. Trigger: Opto-Sensor (covered) or external pushbutton Relay rating: 5 A capacity Power: 12 V DC input Form factor: 2 × 3 inch PCB For: DC test track, window display, point-to-point automation Circuitron SKU: 5400 (Walthers 800-5400) Tip: For DCC reverse loops, you want a true DCC autoreverser (e.g. Digitrax AR1 / NCE Auto-SW). The AR-1 is a DC track-power direction reverser, not a phase-flip module.About Circuitron: A USA-made model-railroad electronics specialist (Maryville, Illinois) founded in the 1970s. Famous for the industry-standard Tortoise slow-motion under-table switch machine and its surface-mount cousin the SMAIL. The full range covers detection (block detectors, Opto-Sensor grade-crossing logic), automation (auto-reversers, external relays, twin-coil alternators), signal / lighting electronics (alternating flashers, ditch-light oscillators, strobe drivers), power supplies, and a complete set of Tortoise / SMAIL replacement parts plus the solderless ZipZ connection system. Most circuits work with AC, DC, or DCC track power unless specifically noted otherwise.In stock at Oakville Model Trains Depot. Show more
