Logic 12b: The logic constructing an OR circuit for various apparatus
Overview (Logic 12b)
This logic is for constructing an OR circuit of a safety input device for safety protective measures of
production machinery, robots.. Safety outputs perform as dual channel outputs.
This logic enables the connection of 4 dual channel direct opening inputs, and 2 dual channel
dependent inputs.
