The schematic is for the Pull Down variant.
This version of the basic LED5 can be used as a sensor input to a PLC, Programmable Logic Controller. The output is an Open Collector NPN transistor and assumes the PLC has the associated Pull Up resistors.
The actual voltage range is from 4V to 28V. (I can make higher voltage variants also.)
I can also make 24V LED5 trackers with totem pole outputs which have both pullup and pulldown transistors. Essentially the same as the standard trackers but with limited drive capabilities.
This circuit does not have a parking function. Parking and Reverse Inhibit functions are best performed in the software of the PLC using timing functions.
Note! If you don't want the 4.7KΩ or 5.1KΩ 1/6thW passive load resisters they can be removed by clipping one of the resister leads. (View)
