●
When the input electrical level type is low electrical level, the voltage range is from 0 V to 3 V.
Note
●
Wiring may differ when connecting the GPIO interface of IO extended module to different types
of external devices.
●
You can design circuit diagram for other external devices according to the diagrams below.
PNP Device
When connecting the GPIO interface of IO extended module to PNP device, it is recommended to
use 4.7 kΩ pull-down resistor.
Figure 4-17 Connect to PNP Device
NPN Device
When connecting the GPIO interface of IO extended module to NPN device, it is recommended to
use 4.7 kΩ pull-up resistor.
