If you are driving a discrete input from a discrete output of another module,
keep in mind that you must measure the output voltage at the discrete output
itself and not at the discrete output power supply. There is a 1.6 VDC drop
between the power supply and the discrete output at maximum current. To yield
the minimum 10 VDC at the discrete output, the discrete output supply must be
greater than 11.6 VDC.
