Contact inputs are isolated in groups of four to allow connection of wet contacts from different voltage sources for each
group. The
CONTACT INPUT THRESHOLDS
value is selected according to the following criteria: 17 for 24 V sources, 33 for 48 V sources, 84 for 110 to 125 V sources
and 166 for 250 V sources.
For example, to use contact input H5a as a status input from the breaker 52b contact to seal-in the trip relay and record it
in the Event Records menu, make the following settings changes:
: "Breaker Closed (52b)"
CONTACT INPUT H5a ID
CONTACT INPUT H5a EVENTS
Note that the 52b contact is closed when the breaker is open and open when the breaker is closed.

The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic equations used to customize the
device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
