The easiest way to add automatic reversing to a section of your layout. 8 amp Auto-reversing control for a single reversing district.Use a double pole, double throw switch to manually allow for reversing.Use one Digitrax booster set for automatic reversing and another set for normal operation.Use a PM42 Quad Power Manager to handle 4 power sub-districts. You can set these up to be automatic reversing or power managers to prevent short circuits from shutting down your layout. Simple to wire.

  • Tunable trip current lets you use it on any layout from Z to G.

  • AR1 operates with or without LocoNet so, it can be used on non-Digitrax DCC systems, too.

- Cost effective automatic reversing for one reversing section or subdistrict
- User selectable trip current lets you adjust the AR1 to work with any scale or equipment on your layout
- Auto-Reversing manages polarity mismatches on the reversing track section without manually throwing electrical toggle switches or adding another booster

- Simple to wire 4 wire hookup, no locomotive wiring required

    Digitrax AR1 Auto Reversing module

    Posted by Thomas on Feb 1st 2019

    This little Digitrax AR1 circuit board module is working great for reversing a locomotive on my single reversing section of track. It didn't start out that way though. The locomotive would short out and stop either at the beginning or the end of the isolated section. I use a Digitrax Zephyr xtra controller and thought this should certainly work with a reversing unit from the same company. So, I went to Digitrax.com, clicked on "support", "tech support depot", and opened "auto reversing" section.
    It was recommended to change a setting in the controller which allows the reverser to have slightly more time to detect a short and switch the direction before the controller stops the train. Very simple procedure, took about 30 seconds to make this setting. Sadly, the older reversing module I had from another company would have probably worked if I had looked up this information before buying a new one. I just thought it was broke! Anyway, this AR1 is working without even the slightest flinch by the locomotive. Very smooth.

    The AR1 worked perfectly right out of the package with no configuration needed. It's very easy to connect and instantly resolved my reverse-loop situation. I'm very happy with MB Klein's quick shipping and service.

    I purchased the Digitrax AR1 reverser and then realized it would not work with my Bachmann Dynamis controller. Model train Stuff staff was very understanding and issued me a RMA number to return the item with very little effort. I will certainly shop with MTS again as their prices are the best......
