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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrigger:\u003c\/strong\u003e Opto-Sensor (covered) or external pushbutton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelay rating:\u003c\/strong\u003e 5 A capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 12 V DC input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm factor:\u003c\/strong\u003e 2 × 3 inch PCB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor:\u003c\/strong\u003e DC test track, window display, point-to-point automation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuitron SKU:\u003c\/strong\u003e 5400 (Walthers 800-5400)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTip:\u003c\/strong\u003e For DCC reverse loops, you want a true DCC autoreverser (e.g. Digitrax AR1 \/ NCE Auto-SW).

Famous for the industry-standard \u003cstrong\u003eTortoise\u003c\/strong\u003e slow-motion under-table switch machine and its surface-mount cousin the \u003cstrong\u003eSMAIL\u003c\/strong\u003e. 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 \u003cstrong\u003eZipZ\u003c\/strong\u003e connection system. Most circuits work with AC, DC, or DCC track power unless specifically noted otherwise.\u003c\/p\u003e\u003cp\u003eIn stock at Oakville Model Trains Depot.\u003c\/p\u003e","brand":"Circuitron","offers":[{"title":"Default Title","offer_id":45098466934966,"sku":"800-5400","price":63.82,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/5131\/1286\/files\/57_159d463a-b749-4e23-a739-fe818dc1c155.jpg?v=1779570185","url":"https:\/\/oakvillemodeltrains.com\/products\/circuitron-5400-ar-1-automatic-reverse-circuit","provider":"Oakville Model Trains Depot","version":"1.0","type":"link"}
