Control desk
This application example shows the possible utilisation of all channel pairs on an input module.
For a typical control desk the following sensors can be evaluated in a safety-related manner:
–
two-hand control device for starting a function
–
emergency stop switch for incidents
–
mode selector switch with 4 positions.
