Hi, all.
I need to pulse each sensor in a stack of of roughly 1500 sensors. There has to be about 20 microseconds in between pulses, or else my 100khz counter will lose tract. I tried using a LDR that fired a LED... which in turn fired the next LDR and so on. With a small cap in each...
Since you want to know what I am trying to do, here it is: 2,688 special miniature infrared sensors have been stacked and staggered into a shaft 7 feet long at 1/32 on an inch apart from each other. Even with 32 point PLC input cards, I would need 84 of them to send all those inputs to the...
Thank you so much for your reply. As each of these timers time out and pulse on, they will check a corresponding sensor for an input. Example: If after the system trigger (starts the 1st timer), a sensor input is returned after .93 seconds, then the PLC can determine it was the 93rd sensor...

First, is it possible to...
