DCC Specialties Frog-AR Quad Output Frog Auto-Reverser.

The Frog-AR is a quad frog auto reverser designed and built by DCC Specialties. It is easy to install and will automatically adjust the connected frog [up to four] to the correct polarity. Each frog can be independently set to operate at 1, 2, 3, or 4 amperes. Unlike other frog controllers, the set current not only determines when to switch the frog polarity, but it also is the maximum current that the Frog-AR will allow to flow to the frog. Limiting the trigger current significantly reduces wear and tear on engine wheels and pickups. The Frog-AR can also be configured to control one or two reverse loops.

Eliminates the need for aux contacts and mechanical linkages

Compatible with low power boosters

Limits current during the reverse cycle - no interaction with circuit breakers

1, 2, 3, or 4-ampere current settings

Can control 4 frogs, or 2 frogs and a reverse loop, or 2 reverse loops
