For an OFF DELAY setting, which operational diagram indicates correct operation?

For an OFF DELAY setting, the operational diagram that indicates correct operation is one that clearly illustrates the functionality during the timing interval after an input signal is removed. In this scenario, when the control signal or input is turned off, the delay timer begins its countdown before the output fully disables.

In diagram I, the representation effectively shows this behavior: the output remains engaged for a specified duration after deactivation of the input signal, consistent with the OFF DELAY operation. This allows for processes where equipment needs to coast down or where an orderly shutdown is necessary, providing a buffer period before the output ceases completely.

In contrast, the other diagrams likely depict different types of control operations, such as immediate disconnection upon signal loss or other timing settings that do not align with the OFF DELAY function. Understanding this distinction is critical for ensuring that systems operate as intended, especially in applications where timing sequences are crucial for safety and efficiency.
