(...) The problem with inductive load is that when current is interrupted, they generate large voltage spikes with reverse polarity. The diode absorbs these spikes and avoids destroying the driver... Philo (21 years ago, 29-May-03, to lugnet.robotics.rcx, lugnet.trains)

(...) Resistors work fine due to the relative difference in cost. The accessory outputs of the earlier decoders are 100ma or so @28V or less, so at most you are dealing with 2.8 w loss (or 100 ma current draw). In order to drop from 14V to 9V, you (...) (21 years ago, 29-May-03, to lugnet.trains)
