DCC Auto Reverse Unit (MRCAD520)

The DCC Auto Reversing Unit is a compact module for model railroads that automatically reverses the polarity of a reverse loop or reversing section to prevent short circuits as a train crosses between power districts.

Designed for DCC layouts with decoder-equipped locomotives, it wires in with a straightforward four-wire hookup and can handle up to 5 amps of current, making it a practical addition for a wide range of layouts. It is not suitable for non-DCC layouts or for locomotives without decoders.
