Inst
allation
A serial resistance is needed to limit the current (usually 10mA) that goes through the LED by using
ULN2803 output to drive LED, which is shown in Fig.2-32
z
To drive filament indicator
An external preheat resistance is needed to decrease the current impact at power on by
using ULN2803 output to drive filament indicator, and this resistance value should be within a
range that the indicator cannot light up. It is shown in Fig.2-33:
z
To drive inductive load (relay etc.)
To use ULN2803 output to drive an inductive load, it requires to connect a freewheeling diode near the
coil to protect output circuit and deduce interference. It is shown in Fig.2-34:
