Widget Posted January 16, 2005 Report Share Posted January 16, 2005 Need i have a relay that needs to be triggerbut the out put need to wait for X nuber of sec. before trigering anther relay to turn on a output. the whole thing will be low voltage to to trigger 110V output Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted January 16, 2005 Report Share Posted January 16, 2005 It sounds like you want a sequential timer.I take it that you want the second relay to turn off after a certain amount of time. This circuit is negative edge trigger, when the trigger is connected to 0V, if you want posative connect the input to 0V with a transistor. OUTPUT 1 will be on for a certain amount of time then turn off and OUTPUT 2 will come on. Connect the outputs directly to the relays (with a diode in reverse parallel)EDIT: Just remembered the schematic.Any questions are welcome.
