I need to track the motion of a 24-slot chopper wheel running at up to 100 rpm (~40 Hz maximum). I've got a Fairchild H22A1 slotted optical switch and a 5 VDC supply. What is the simplest circuit that I can build which will link to a Keyence Visual KV16 PLC?
The only circuit I've come across so far is a honeybee counter by David Johnson (attached). How much can this be simplified for my needs?
