TAMS Elektronik 44-01606-01 S88-6 Signal decoders Module

In feedback sections, the locomotive is supplied via the center conductor and the continuous external conductor. An interruption of the ground connection on the continuous rail (e.g. due to contamination) has a direct effect on the driving behavior. In the worst case, the locomotive stops or does not start again after a stop in the feedback section. The problem can be solved by connecting the two outer conductors together using a diode. This so-called "diode trick" uses the fact that only a half-wave of the digital voltage can be used for the feedback in the s88 bus. By installing a diode, the other half-shaft is "diverted" from the insulated to the continuous rail and thus an additional ground connection is established. With the s88-6, the diodes are integrated in the circuit, so that the complex retrofitting of diodes is not necessary.
