Block Signalling REV1 DCC Autoreverser

The BLOCKsignalling REV1 Autoreverser is used on DCC layouts to automatically switch the polarity of track feeds in layout features such as loops, wyes and to provide feeds for turntables.

Whenever a train crosses a section of track where there is a polarity mismatch and a short would result, the autoreverser automatically switches the polarity to prevent a short circuit and so avoid subsequent shutdown of the layout.

A short is detected in less than five microseconds, and the polarity is corrected within 10- 20 milliseconds.  Detection level is approximately 1.75A.  For DCC layouts only.  Suitable for up to OO/HO scale.

Works with all DCC command stations which can provide 2.5A output or greater.
