Dry Contact Inputs

The 8 dry contact inputs can be programmed for normally open
(NO) or normally closed (NC) operation. In addition, you can have
the Skymetry WTU-14 count the number of times the input changes
state (pulse count) and maintain the amount of time that the input is
in the opposite state (Run Time). Click on the Dry Contact Tab to
display the main status screen.
