This board is an automatic polarity reverser for a single frog.  Setup is simple, connect two wires to the DCC bus and one wire to a frog.  The frog should be fully isolated.  When a train crosses the turnout and the frog is the wrong polarity, the frog juicer will reverse the polarity so quickly that the train and the rest of the DCC system will never notice.  Should not be used with boosters over 5 Amps.

This board can be configured to use as an automatic polarity reverser for two frogs, a reversing loop, a turntable, a wye, or a crossing. It uses the same basic design as the hex frog juicer but has 33 Amp transistors so it can be used with multi-unit lashups and 10 Amp boosters. Setup is simple, connect the input to the DCC track bus, and connect the output wires either to two frogs or two rails. A jumper controls whether the two outputs act as a pair (i.e. an auto-reverser) or independently (i.e. a pair of frog juicers). Another pair of jumpers controls the current set point for switching, either 2 Amps or 4 Amps. When used for frogs or crossings generally 2 Amps work best and for an auto-reversing application, 4 Amps generally works best.\u003c\/p\u003e","brand":"Tam Valley Depot","offers":[{"title":"Default Title","offer_id":51813959074078,"sku":"TVD DFJ003","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/8069\/9166\/files\/600_dual_juicer_P7118109__21340.1698513907__01622.1729384587.1280.1280.jpg?v=1777919614"},{"product_id":"tam-valley-depot-dcc-hex-frog-juicer-and-auto-reverser-v3-1","title":"DCC Hex Frog Juicer and Auto-Reverser v3.1","description":"\u003cp\u003e\u003cstrong\u003eDCC Hex Frog Juicer\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eFor DCC systems 2 Amps to 8 Amps including NCE PowerCab.
