DCC Dual Frog Juicer and Auto-Reverser

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.

They will not work with DC or 3-rail. They will work with most all DCC systems, Lenz, Roco, NCE (including the PowerCab), Digitrax, Zymo, MRC, CVP. If you don't see your DCC system here, don't worry, there are just too many to list them all!

Alas, they will not work with the Bachmann EZ-DCC system or the SPROG II as they do not have enough power to reach the 1.7 Amp switching threshold. However, if you use one or our boosters then you can use frog juicers and other auto-reversers with these systems.
All Frog Juicers work with Peco electrofrog turnouts without any modification to the Peco turnout. The same applies to other power-routing turnouts (e.g. older Shinoharas). You still need to insulate the Peco electrofrog turnouts as in the instructions that come with the turnout. For a normal turnout, that mans using insulated rail joiners on the 2 rails leaving the frog.

Peco Insulfrogs do not need a frog juicer as the frog is plastic and cannot be powered.
Trouble with your PSX ciruit breakers shorting faster than the frog juicers?

Older versions of the PSX were slower and the frog juicer would trip before the PSX ciruit breaker. Newer ones are set faster than the frog juicers. You can slow the PSX down by programming it. Thanks to Larry Puckett and his website DCC Guy for this tip:

"The solution is to slow down the PSX and give the Frog Juicer enough time to do its job. On the PSX set CV55=1 and CV65=128, and the PSX delay should work with the Frog Juicers."
