Caution:

If you use light-emitting diodes (LEDs) you must always operate them

via a series resistor.

LEDs are available in many different models. There are LEDs with 2-5

mA, but also LEDs with 15-30 mA power consumption. The series

resistor limits the current flow of the LED and will need to be calculated

for each model. Ask for the max current rating when buying your LEDs.

You can connect several LEDs in parallel to each output. In this case

every LED must have a series resistor of its own. If you connect several

LEDs to one output in series, only one series resistor is needed. The

number of LEDs connected in series to one output depends on the

digital voltage.

You can determine the number of the LEDs that can be connected in

series to one output from the following formula:

(number of LEDs + 2) x 1,5 < digital voltage

Fixing the locomotive decoder

After completing all connections fix the locomotive decoder with double-

sided adhesive tape, for example.
