Operation
If the input block terminal is open (impedance > 50 KΩ) in relation to the Digital Ground terminal or
with a voltage between 3 and 24 Vdc, the signal will be considered as high logic level and the value
100% (high logic level) will be available in the block output.
If, on the other hand, the input is short-circuited (impedance < 200Ω) or with a voltage between 0
and 1.7 Vdc, the signal will be considered as low logic level and the value 0% (low logic level) will be
at the block output.
This condition can be inverted by the parameter CNOT.
