Connecting light bulbs
As a rule you can connect one or two bulbs to one output. Bulbs are
not polarized. Connect one side to the output, the other to the return
conductor.
Caution: The maximum current of 100 mA per output should not
be exceeded. In this case the output would be damaged. For that
reason strictly uphold the specification of the current consumption
(given in mA) on the bulb´s socket or it´s packaging.
Connecting LEDs
You can connect several LEDs in parallel or serial (in series) to one
output (see following sections). Which version fits better depends
amongst others from the mounting situation.
LEDs are polarized. Connect the cathode (-) to the output and the
anode (+) to the return conductor. With wired versions the anode (+)
has the longer "leg", with SMD versions the cathode (-) is marked (e.g.
by a reamed corner or a paint mark).
Caution: LEDs always have to be connected via a series resistor,
otherwise they will be damaged when put into operation. Advice
concerning choosing a series resistor "Parallel / Serial connection of→
LEDs".
