In an OFF-Delay Relay operation, what happens after S1 is pushed and released?

In an OFF-Delay Relay operation, when S1 is pushed and released, the relay is activated, which allows the output to energize for a specified delay period before eventually turning off. During this delay, the output device (M) remains operational. However, once the delay period is completed, the output will stop.

If S1 is pushed and released, the relay waits for the delay time before M is essentially allowed to stop. Therefore, the choice indicating that M remains stopped is not accurate in describing the immediate effects of an OFF-Delay Relay; rather, the output device will momentarily remain powered during the delay period initiated by the pressing of S1. Consequently, the correct understanding is that M will not be immediately stopped but will remain powered until the delay period concludes.

In the context of OFF-Delay Relay functionality, it is crucial to distinguish that the relay’s action allows for operations to continue for a brief period before ceasing, rather than stopping immediately upon the release of the switch. Therefore, interpreting the operation of an OFF-Delay Relay correctly emphasizes the continuation of output operation until the set delay time has elapsed.
