Ok so the operatives at work are wining about how hard their jobs is, the usual.
The scenario is at the moment they have a set of vibrators on dust silos that feed onto a conveyor belt, the current set up is an on/off switch on the control desk that switches the vibrators on via a contactor. The problem being they forget they have switched them on and if the belts running slowly it just compacts the material in the silo and causes a blockage. They've been told that they are only to be used to clear a blockage not all the time, but you know what there like.
What I'm after is a relay that once energised will close for a set time and then open for a set time and repeat whilst it has power to it. (hope this makes sence). This way when the belts running slowly it'll still have chance to run out of the silo before settling.
I have worked a control circuit out using a couple of omron timer relays I'll upload a drawing when I get to a computer, there is 12 silos I'll have to convert to running like this, so I was wondering if there's a one off unit that will do the job just to work out and see what the costs will be for each option. If there is such a thing i'd only need 12 of them rather than 24 timer relays.
Cheers
