The Velleman VM141 Start/Stop Delay Timer Module can be used in a wide range of applications where a device needs to be activated for a user adjustable time period of between 1 Sec and 60 hours.
Four time delay periods are set using 2 jumper switches and a potentiometer is used to adjust the time within these 4 ranges:
Features onboard START and STOP (reset) buttons plus inputs for your own external buttons. A 3-LED rotating display indicates timer is active and counting down.
The timer is activated using the onboard START Button or the START Input (push-button contact closure). The timing sequence is non-retriggerable and will be completed regardless of further trigger signals or if the button contacts remain closed after activation. Once finished (or the board is reset using STOP), a fresh trigger signal is needed to start a new timing period.
The countdown can be cancelled and the board reset at any time using the onboard STOP Button or the STOP Input (push-button contact closure) or by removing the power supply.
Optional "Powert-On" mode possible by closing Start input so delay countdown commences immediately power is applied to the board. The relay will stay on until the user-set time period has elapsed. The power must be removed and reapplied for a fresh countdown to commence.Features
