Logic 11b: The logic for apparatus with NO/NC contact inputs
Overview (Logic 11b)
This logic function is for using dual channel NO/NC contact devices as safety protective measures
for semiconductor manufacturing machines and food packaging machinery. Safety outputs perform
as dual channel outputs.
This logic has 2 dual inputs for direct opening inputs and 4 dual channel inputs for NO/NC contact
devices.
