The ______ timer operates opposite to the on-delay timer.

Understanding how timers respond to input helps explain why this timer is opposite to the on-delay. A timer on-delay starts counting when the input goes active and only after the preset time does the output energize. If the input drops before that delay finishes, the timer resets and the output stays off. An off-delay timer, by contrast, energizes the output right away when the input is active, and then, once the input goes inactive, it waits the preset time before turning the output off. So it delays turning off instead of turning on, which is the opposite behavior to an on-delay timer. Other timer types—like interval timers that repeatedly cycle on and off at fixed intervals, or pulse timers that produce a single fixed-width pulse—don’t match this off-delay behavior.
