output voltage
Discrete IO :
User definable Input/Output selection done by software,
Input High voltage 3.0V
… 35.0V.
Input Low voltage max. 0.8V
Output High voltage:
Internally driven min. 4V default,
Externally supplied: up to 35V max
Output Low voltage 0.4V max
Maximum Sink Current of each open collector 100 mA
Please note: When the default 5V for the discrete outputs are not
used, provide a serial resistor in line with the open collector
transistor. If using a discrete pin as input, make sure that the
output mode is set to default before connecting an external
voltage. Otherwise the transistor can be damaged.
