In TOF, after the input goes false, the output Q will:

• A. De-energize immediately.
• B. De-energize after the preset delay.
• C. Remain energized for the off-delay period.
• D. Remain energized indefinitely.

Answer: (C)

TOF is an off-delay timer. When the input is true, the output is energized and no timing occurs. When the input goes false, the timer starts counting down the preset off-delay, and the output remains energized during that period. Only after the off-delay expires does the output turn off. This keeps the load running briefly after the stop signal, rather than turning off immediately or staying on indefinitely.
