🔍 Key Concepts

• PLC ladder logic representation of field devices (how inputs and internal relays are shown) • Typical three‑wire motor control circuit: start (momentary), stop (normally closed), and holding/seal‑in contact • Difference between momentary pushbutton and maintained selector switch in a motor starter circuit

💭 Think About

• Look at how Internal relay 1 and Output 1 interact with Input 1 and Input 2. Which device must be pressed only to start, and which one must remain closed for the motor to keep running? • In a simple motor controller, what is the usual function of the lower series contact that all current must pass through before energizing the control relay? • Compare the symbols around Input 2 with the symbols for normally open and normally closed contacts in ladder diagrams. How would a stop function normally be drawn?

✅ Before You Answer

• Identify which contact in the diagram provides the seal‑in/holding circuit for the motor once it is running. • Decide which device in a standard motor circuit is momentary (used only to initiate) and which is maintained (must stay in the same position). • Verify whether a stop function in motor control is usually drawn as normally open or normally closed when the system is at rest.
