New reverse loop module for the new digital LGB system world. You can switch the reverse loop on your digital layout automatically and free of short circuits. You will protect your digital layout and the rolling stock in the process. One more advantage of the reverse loop module: Several reverse loops can be used simultaneously on the layout. Reverse loop modules in use up to now cause a short circuit when the train enters the reverse loop and force the polarity of the track to switch by causing a break in the voltage, example: 55080. This new MTS reverse loop module by comparison switches free of short circuits; and interruption of the voltage in the track is avoided. The overloading of the MTS central unit by the intentionally caused short circuit is thereby a thing of the past. This protects above all track components such as locomotive decoders, turnout decoders, and the electronics customarily installed in locomotives and cars. This module is compatible with the previous components. Notes: Due to technical changes, the previous MTS reverse unit model (LGB 55081) is being discontinued and replaced by the new 55085 version. This new module is suitable to a limited extent for analog operation. This product is not weatherproof and must be protected from moisture. 80 x 70 x 20 mm / 3-1/8" x 2-3/4" x 3/4".
