In an ON-delay relay, what is the state of the NO contacts immediately after the coil is energized?

In an ON-delay relay, when the coil is energized, the normally open (NO) contacts will not immediately close. Instead, there is a built-in delay period during which the contacts remain open. The purpose of the ON-delay feature is to allow for a specific period of time to pass before the NO contacts close, thus enabling the relay's output to activate only after the prescribed delay has elapsed.

Once this delay period is over, the NO contacts then close, allowing current to flow through the circuit that is being controlled. This characteristic is essential for applications where it's crucial to prevent immediate activation or to allow time for certain conditions to stabilize before enabling connected devices. Therefore, the correct description of the behavior of NO contacts in an ON-delay relay is that they close after a delay.
