Mains powered 2 to 45 minute DOUBLE delay timer modules with a mains rated relay output. When activated, the 1st delay time starts but the relay remains off. On completion, the relay turns on for the 2nd delay time and then turns off. Both delay timers are adjustable.
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 Start-on-PowerUp mode is available. In this mode, the timing sequence described above commences immediately power is applied to the board. The Start Input is disabled when this mode is selected. Start-on-PowerUp mode is set using a header jumper not included (Order Code JUMPER-RED).
Both delay periods are independently adjustable from 2 to 45 minutes 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. The boards have reverse polarity protection.
