Regardless of digital system, voltage or system! Works with any voltage and any digital or analog system. NOTE: The internal current measurement reliably and quickly detects an entrance. This may need to be be adjusted to the track width. Default 3.5A set (for large railways). For small tracks (H0 etc.) the current limit should be approx. 1A can be set (CV114 = 10). This reversing loop module, which can work ANALOGUE and DIGITAL and has up to 15A continuous output, has an integrated decoder in which the current strength can be adjusted if necessary. can be adjusted (but does not have to be). It works completely without short circuits and without sensor tracks or any other high wiring effort. Simply connect it to the track and the section will work without any short circuits! The module su.
