1 to 180 second DOUBLE delay timer module with a mains rated relay output. When activated, the 1st user-set delay time will commence but the relay remains off. On completion, the relay turns on for the duration of the 2nd user-set delay time and then turns off.
Timer is activated via the Start Input (using for example a push button or relay contact closure). The timing sequence is non-retriggerable and will be completed regardless of further trigger signals or if the contacts remain closed after activation. Once finished, a fresh trigger signal is needed to start a new timing period.
An optional "Instant-On" mode disables the trigger input and commences the delay countdowns immediately power is applied. Power must be removed and reapplied for a fresh countdown to commence.
Both delay periods are independently adjustable from 1 to 180 seconds using the onboard potentiometers (header pins allow the use of user-supplied external potentiometers if required).
An LED indicates that the timer is in operation.
