In sequencing, what device provides a time-based delay before a signal is sent forward?

In sequencing, you need a component that holds things up for a precise moment before the next action starts. A time-delay relay provides that time-based pause: when the input signal energizes, its output turns on (or off) after a set delay, giving you a controlled interval between steps. This helps ensure previous actions have completed and the system is ready for the next stage. Other devices here don’t add timing by themselves. A safety interlock gates operation for safety and isn’t about delaying signals. A limit switch detects position and sends a discrete signal when a travel limit is reached, with no built-in delay. A pushbutton is just a manual input without a built-in timing function. So the device that introduces the delay before forwarding the signal is the time-delay relay.
