WebIn particular, the relays are On-Delay relays normally open, with timed closed contact. A similar hard-wiring could also be used for sequential power-off, but the sequential power on is preferred because it will allow a check of the correct mounting and functioning of the sensors each time the machine is started. WebTime 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-open.
