I have a section of rollers which have a sensor at the end. When product is moved onto the sensor then the rollers stop.
If this sensor happened to fail the product would fall and potentially cause damage.
Can anyone think of a way to monitor this sensor to check whether it is working or not.
The sensor is a simple 3 wire PNP sensor.
I could have another sensor afterwards but if the 24V was missing from both then the fault would still happen.
