WebREVIEW: Time delay relays are built in these four basic modes of contact operation: 1: Normally-open, timed-closed. Abbreviated “NOTC”, these relays open immediately upon coil de-energization and close only if the coil is continuously energized for the time duration period. Also called normally-open, on-delay relays. 2: Normally-open, timed ... WebA usually closed (NC) or break contact cannot reclose if a normally open (NO) or make contact remains closed. The NO contacts will not shut if a normally closed (NC) contact fails to open when the relay is turned on. For switching, a standard relay uses simply mechanical connections.
