I have a set of CUB5 counters set up on a machine. They are triggered with photo sensors. I am using 24vdc to power everything. I use the current sinking input on the counters.
The problem I am trying to solve is that some of the items we are counting have areas where the photo sensor can shine through and trigger the counter more that one time for that particular item. There is no practical way to avoid this.
I would like to try to find a way to only count the item if it blocks the sensor for over a certain time period, probably somewhere in the almost 0 to 1 second range. Probably would initially need to be adjustable, although this could be done with different resistors rather than a potentiometer. I know this is a very small time, but these counters seem to be rather sensitive. (I'd bet they would count a fly if it flew by the sensor.)
I do have some limited (read very limited) electronic knowledge. If I have a schematic and the part numbers of components, I should have no trouble building it.
Thanks.
