11.3 External IO interface
The external IO interface has 4 digital inputs or outputs, the GPIOs 0 to 3.
Each
can be configured as input or output.
Device Destruction!
Ø
At the I/O signal pins of the External IO interface use exclusively 3.3 V
or 24 V signaling voltage. Higher signaling voltages lead to severe
damage to the NANL-B500G-RE device!
Ø
To operate the NANL-B500G-RE device, at the I/O signal pins of the
external I/O interface, take a maximum of 1 mA (at 3.3V) or 600 mA (at
24V) current. Otherwise the netX chip and other components may be
damaged.
