MRC AD520 DCC Auto Reverse Module

When a DCC decoder equipped locomotive passes the insulated gaps leading
into or 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. 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 using the DCC command station.

Simple pictorial instruction sheet clearly shows wiring directions.
Auto Reverse Module has red and yellow wires protruding from its
small, black, box-like structure.
Connect the two yellow wires to the reverse loop section and the two
red wires to the main line section as shown on instruction sheet.
Rating: 2.0 amperes.
Phone number and address for MRC servicing needs are included.
