delay before the output is turned off.

Answer / andy

On-delay:
Output contacts change state after input signal is present for selected time. Output contact can be normally open or normally closed. Contacts return to shelf state after input signal is lost.
Off-delay:
Output contacts change state when input signal is applied. Contacts return to shelf state after input signal is lost after a selected time.
Note:
Outputs can energize or de-energize devices after timing sequence since contacts can be normally open or closed.

Answer / andy

On-delay:
Output contacts change state after input signal is present for selected time.  Output contact can be normally open or normally closed.  Contacts return to shelf state after input signal is lost.
Off-delay:
Output contacts remain in shelf state when input signal is applied.  Contacts change state after input signal is lost for a selected time.
Note:
Outputs can energize or de-energize devices after timing sequence since contacts can be normally open or closed.
