ou can thus parameterize the output with a DC 5...7.5 V input suitable for
controlling a magnetic valve, for example.
The greater of the signals is valid (maximum selection) when the modulating output
of 3 controllers is controlled.

Inversion No, Yes No
Meaning:
No: 0...100% load = 0...100% output.
Yes: 0...100% load = 100...0 % output.
