🔍 Key Concepts

• PLC motor starter circuits typically use the PLC output to drive a motor contactor coil, not the motor itself • A latching (seal‑in) circuit uses a parallel, normally open contact from the same device as the coil to keep the coil energized after the start input is released • In ladder diagrams, a diagonal slash through a contact symbol indicates a normally closed contact; no slash indicates normally open

💭 Think About

• Look at the Output coil in figure A: in a simple motor controller, what physical device would that coil most realistically energize? Could a PLC output safely power a motor directly? • Study the contact labeled "Output" drawn in parallel with Input A. Is it drawn as normally open or normally closed, and how does that relate to the idea of a holding or seal‑in contact? • Check Input B’s symbol: is it normally open or normally closed, and what common motor‑starter function (start or stop) is usually wired as normally closed in basic control circuits?

✅ Before You Answer

• Confirm whether the contact labeled Output is drawn as normally open or normally closed • Decide whether the Output coil in a PLC ladder normally represents a motor contactor coil or the motor itself in standard practice • Relate the function of the parallel Output contact to a typical seal‑in/holding circuit used to keep a motor running after the start pushbutton is released
