Input Circuit of the PB1650DIO2.1
The input current must not exceed 10 mA. The input circuit does not invert.
Input levels <1.5 V are interpreted as a logical 0 (low), and input levels >3.0 V
as a logical 1 (high). The switching state is undefined in the range 1.5 V to
3.0 V.

Outputs
The output drivers consist of a bipolar transistor switch and an optocoupler.
There are eight parallel, dc decoupled output channels and two parallel control
lines, H2E and H4E, which can be configured as outputs.
