What is difference between ON delay and OFF Delay Timer?
Answer Posted / 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.

Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
