Hi, I have a circuit I want to build, I currently Have a working model but would like a suggestion of what you experts (im only a beginner in this field) might think would be the most suitable circuit for the following application
I have a PNP analogue sensor that gives a 0-10v output.
Under test it gave 10.9v out when not sensing, when sensing it droped away towards 0v.
I need to provide a digital signal (0-24 v) when the output from the sensor drops to 10.5 volts.ie: My circuit should output 0v when the anlalog input is 10.9v, and switch to 24v once the analog sensor drops past 10.5v.
The circuit needs to be powered from a 24v supply.
The current circuit I have built is simply a comparator circuit with a voltage reference, using LM358 chip. The output of this circuit (0-24v) then drives a transistor.
I would like it to switch cleanly and quickly if possible.
If you require any other information please ask,
Any ideas would be much appreciated .
Attached is the current circuit I have that works but some values may need adjusting or if someone thinks a complate circuit change is more suitable then please suggest a sdiagram with values for me.... thanks again...
