NOTC contacts are associated with which type of timing relay?

NOTC (Normally Open, Timing Control) contacts are typically associated with on-delay timing relays. With an on-delay relay, the output remains off when the input is activated, and only after a predetermined time delay does the contact close, allowing current to flow through. This is useful in applications where equipment needs to be delayed before starting up or for systems requiring a warm-up period.

In contrast, other types of timing relays function differently. Off-delay relays turn off after a set period when the triggering input is removed, interval relays cycle the output on and off during the timing period, and recycle relays turn their outputs on and off at specified intervals. This differentiation clarifies why NOTC contacts align specifically with on-delay timing relays, where they remain open until the delay period has elapsed, ensuring that the circuit is activated in a controlled manner.
