DCC AUTO REVERSE MODULE
 
The reverse module watches the current while the locomotive entering the isolated loop section from either direction and reverses the rail polarity avoiding short.
 
There are no settings, the Module is ready to use.
LED shows a short condition.
 
Just connect the „DCC” terminal to the rails before the loop section and the „OUT” terminal to the loop.
 
Trip current is 3 amper - so it is suitable for bigger gauges (H0, OO)
 
The module can be used for turntables as well.
 
I do not recommend using it with Roco z21.
