Dependent on UIO-256 DIP Switch SW1 Settings for Input/Output Range as summarized in Table 8.
**
Inputs will sink 100 mA max at a maximum input voltage of +18 VDC. For operation from an external DC voltage source,
connect the external control voltage to the "plus" pin, and connect the external common to the "minus" pin. The UIO-256
also has an internal 18 VDC source, which is available at pins 18 to 22. Ground is available at pins 24 and 25. To use the
internal 18 VDC source, ground the “minus” pin for the desired control input, then use an external switch to connect from
the 18 VDC internal source to the "plus" input pin.
