3.10 X8: External diagnostic LED connections
X8 allows for connection of additional external LEDs in parallel with the internal diagnostic LEDs.
The external LEDs are connected as shown in Figure 16

Figure 16: Connecting external LEDs to X8
Note:
The outputs on X8 are intended for switching an external LED only. Overloading the
outputs with other loads may destroy them.
If only one output is used the maximum current consumption is Imax=15mA. The total
current consumption of all 5 outputs together should not increase 25mA. The off-load
output voltage is 3,3V and is supplied via a 220Ohm series resistor.
