12Vdc DOUBLE Delay Timer Relay Module, 0.1 Sec to 4 Min

New improved DIN-Rail size version with wider time range and easier setting.

0.1 seconds to 4 minutes 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. In this mode, the the relay turns on and the delay countdown commences immediately power is applied to the board. The relay turns off when the user-set time period has elapsed. Power must be removed and reapplied for a fresh countdown to commence. Instant-On mode is set using a header jumper not included (Order Code JUMPER-RED).

Both delay periods are independently adjustable from 0.1 seconds to 4 minutes using two scale switches and 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.

A 2 to 45 minute version of this board is available (Order Code CI034)
