Description

For all DCC systems including NCE PowerCab.  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.

    Tam Valley Depot AUTOMATIC POLARITY REVERSER "DUAL FROG JUICER", 2 FROGS

    Posted by Jay Lennox on 2023 Jan 15th

    I purchased two of these and both worked as expected. The model railroad club I belong to has 5 of these installed automatically controlling the polarity of 2 crossovers (diamonds), 2 reversing loops and 1 turntable. They are very reliable.
