Table 8. UIO-256 Relay Outputs Connector (J5)
* Dependent on UIO-256 DIP Switch SW1 Settings for
Input/Output Range as summarized in Table 7.
The relay contacts are rated for 0.5A at 120 VAC;
1A at 24 VDC; 0.3A at 60 VDC.
* Dependent on UIO-256 DIP Switch SW1 Settings for
Input/Output Range as summarized in Table 7.
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 "+" pin, and connect the
external common to the "-" 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 "-" pin for
the desired control input, then use an external switch to
connect from the 18 VDC internal source to the "+" input pin.
