🔍 Key Concepts

• Study how each output coil (A, B, C) is wired in relation to the input contacts above it in the ladder diagram. • Compare the timing of inputs vs outputs in the input/output diagram: does any output stay on after its input turns off, or does it follow it exactly? • Look for whether the logic makes outputs happen in a step-by-step chain (one enabling the next).

💭 Think About

• When Input A first turns on, which outputs are able to energize, just from the wiring? Trace the power path from the left rail through the contacts to each output coil. • As Inputs B and then C turn on and off, do the outputs show any sign of being held (latched) or inverted compared to their inputs? • Does each additional output depend on the presence of the previous input conditions, suggesting a particular pattern of control?

✅ Before You Answer

• Verify whether any output remains energized after its own input has gone low; if so, that would indicate some form of latching. • Check if any output is ON exactly when its input is OFF, which would indicate inverting behavior. • Confirm whether the diagram shows a cascading enable path (e.g., Input A must be true before Output B or C can ever turn on).
