MRC AD520 AUTO REVERSE

The MRC DCC Auto Reverse Module will automate the operation of
your DCC reverse section with simple 4-wire hookup.

Operation – When a DCC decoder equipped locomotive passes through
the insulated gaps leading into or out from a reverse loop section, the
MRC DCC Auto Reverse Module will automatically match the track’s
polarity and maintain the same travel direction for the locomotive.
Note: This unit was not primarily designed for use with standard
locomotives and will cause a non-decoder equipped locomotive to travel
in reverse after passing an insulated gap. When this happens, simply
change the direction of the locomotive by using the DCC command
station.
