Title: Connect a PLC with electrical components.
Course: Mechatronics III (13901-III) > Section: Understanding Programmable Logic Controller Systems

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?
