Logic 12A: The logic for apparatus with a two-hand control device
Overview (Logic 12A)
This logic is for using two hand input devices for safety protective measures of production machinery.
Safety outputs perform as dual channel outputs.
This logic enables the connection of 2 dual channel direct opening inputs, 1 input device for
two-hand control (2 dual channel NO/NC inputs), and 2 dual channel safety inputs.
