TIME-LAG AUXILIARY RELAYS
Delayed auxiliary relays
Delayed auxiliary relays are used in sequential control schemes requiring either a time-delay on pick-up (energisation: the output contacts change position at the end of the preset time initiated by the closure of a control contact external to the relay), or a time-delay on drop-off (de-energisation: the same operations occurs at the end of the preset time initiated by the opening of a control contact external to the relay).
The rating and clearances used for the output contacts allow them to be used directly to control switching equipment.
