light sensor 4-20 mA or 0-10 Vdc

Hi, can anyone get me a circuit drawing for a light sensor with 4-20 mA or 0-10 V output. Supply voltage should be 24 VDC. I want to connect this to a analogue plc input to control the outdoor lights with it. I looked on the net but seems hard to find and i don't have the knowledge

Thanks

??????? how do we supply schematics when we don't know what sensor your using? Plus if you have a particular sensor you can get the data sheet by entring the part number on the web. Or is your question that you need to find one that suits your needs if so we will need further info such as sensing distance, type of sensor (thru beam, retroreflective, diffuse, light mode or dark mode, npn or pnp sink or source ie do you want a 0 volt active or a 10 volt active. 4-20 MA sensor sounds like a distancing sensor is this what your looking for??

If, instead of sensing an object, you mean to sense the light level try here: http://www.controldepot.net/browseproducts/Outdoor-CelestialLight-Sensor0-10-VDC.HTML

If all you really need to do is sense when it is dark to turn lights on, check out this link...
