I'm looking at a FIFE SE-46A line guide which, according to FIFE, will give a 0-10ma signal output depending on where the line is currently located in the entire bandwith of the sensor. I would like to interface this sensor with a micrologix plc which will be used to control two outputs moving a hydraulic cyclinder left or right, based on the sensor's feedback. I'm trying to figure out how will I know if the line is to the left or to the right of the sensor??? What signal will I get? Does a line on dead center mean 5ma?
