Description
DC 0
～
30V
I/O output swing range, 30V is limit voltage which should not be
exceeded, otherwise it will cause damage to the device
DC+3.3V
～
+24V
Any voltage within this range can be used to indicates logical 1, it is
defined by user
DC
＜
3.3V
I/O output may go wrong if logical 1 has been set within this range,
it is advised to use 0V to indicates logical 0
The max sink current of isolated I/O output is 50mA.
