No power required delay off function. Upon application of the supply voltage the relay operates.
When the supply voltage is disconnected the time period starts and at the end of the time period
the relay releases, the time is reset and the relay remains released until the supply voltage is reapplied.
For time ranges above 600 sec there is a built-in battery.
This timer is not to be used for short pulses, as battery requires 24H to recharge. Use IAP1 or 2.
