Connect a PLC with electrical components.

Connection may include the use of components such as

  • normally open (NO) momentary (start)
  • normally closed (NC) momentary (stop)
  • sensors
  • contactor and solid state relay
  • status lamps
  • drives (e.g., variable frequency drive [VFD], microstepper, servo).

Process/Skill Questions:

  • What enables an emergency stop button to shut down a system immediately?
  • What is the purpose of a status lamp?
  • What happens if NO and NC switches are accidentally swapped in a hydraulic lift?
